Big 3 East: ALG Defense RMR 6 Second Mount

IMG_6440

At Big 3 East, ALG Defense showed off their new 6 Second Mount. The 6 Second mount was originally made with an Aimpoint T1 in mind. Well now they have offered it so you can use an RMR if you want.

The ALG Defense 6-Second Mount was designed when a counter-terrorism unit approached ALG with a strict set of criteria. When entering a linear environment, such as an airplane or bus, the team’s primary weapon was their pistol and they were looking for a fast sighting method that was rugged and robust. Red dot scopes mounted directly to their pistol slides were showing a high failure rate due to extreme acceleration or deceleration of the slide. The balance of the pistols was thrown off from the rearward scope mounting position, and the slides were weakened from machining a pocket for the scopes into the top of the slide.

The name, 6-Second Mount, comes from a description used by one of the operators:
“The fight lasts 6 seconds… Either they’re dead or you’re dead, and aggression saves the day.”

Mounting an optic to your weapon decreases engagement time, allowing for faster and more accurate hits on target. By separating the sight from the reciprocating slide it allows the pistol to function properly without the added mass of the optic sight, and produces a favorable weight distribution.

The ALG 6-Second Mount in machined from 6061-T6 aluminum and is designed to Gen 3 Glock 17, 22, 24 31, 34 and 35.

I shot this gun and a normal 6 Second Mount with a Hilux Micro Max B-Dot. Both were very easy to pick up the red dot and decreased my target acquisition time. With the frame mounted optic, I found it easier and quicker to pick up the red dot during and after recoil. I prefer the larger sight picture of a micro red dot like the Hilux B-dot or an Aimpoint T1. I would like to see the 6 Second mount modified for the new Trijicon MRO.

Price and release date is TBA. They are hoping to keep the price similar to the existing 6 Second Mount and hoping for a release around or before Shot Show 2016.

    Looks nice, but at $250 I think the rear sight plate mount is a simpler and much cheaper solution.

    • Nick

      Sure, until you have to replace your fancy $500 red dot.

      They said the military unit it was intended for was seeing a high failure rate on slide mounted optics.

      • nobody

        I would take any claim like that from people who are trying to sell me something with a whole shaker of salt. Especially considering their mount doesn’t allow you to use your iron sights in the event that your optic fails, which is a feature that should be expected for anything that was being designed for military/special forces/super operators.

        • dhdoyle

          First, ALG is professional. If they say something, you can rest easy that they aren’t BS-ing anybody.

          Second, I know folks that have RMRs mounted on their Glock slides, and yes, they fail with some frequency. They accept the relatively low MTBF as a trade-off for fast, decisive target acquisition. The idea works when you have a budget and an armorer that can quickly replace the MRDS as needed.

          • Nicks87

            I think they ARE BS’ing everyone. If this was built for some special ops group then why not just say who it is? This kind of stuff isn’t classified or considered sensitive equipment. Plus why would this “unit” use pistols for linear assaults when every manner of sub-gun or SBR would be available to them as well?

          • nobody

            >Plus why would this “unit” use pistols for linear assaults when every
            manner of sub-gun or SBR would be available to them as well?

            To add to this, unless your shooting style of choice is center axis relock and you’re okay with the slide on your pistol potentially connecting with your eye socket in those 6 seconds, any long gun less than 23″ long will stick out less when shouldered and if you’re worried about having to bring it in closer to your body to fit through places there are plenty of sub 14″ long subguns (and if that’s to long, the Brugger & Thomet MP9 is only 12″ long) that you could use with a single point sling like the SAS did during the Iranian embassy siege. You have so many choices subgun wise that there is no excuse for just using a pistol.

          • All the Raindrops

            Pistols still have their place for clearing confined spaces, though adding one of these, a suppressor, a light, etc, pushes the size up a lot. Still, there are people who like them.

          • FarmerB

            Think about an Air Marshall. Maybe they don’t have an SBR available. Or maybe they are using pistols because they are keeping the speed down (and using special ammo) to stop penetration of the fuselage? There could be all sorts of reasons we cannot think of

          • milesfortis

            Fuselage penetration isn’t the “Goldfinger” blowout you might imagine. Even several bullet holes don’t make that much difference.
            Think about the interior of any size passenger airliner; commuter, small large, or even jumbo on the ground.
            What’s inside that’s the same?

          • FarmerB

            I didn’t imagine anything of the sort – there are many reasons why you don’t want to put holes in airliners.

          • milesfortis

            Oh, I agree. Holes in any airplane in flight are never to be a ‘wanted thing’, but, the Air Marshal’s use .357 SIG. For what that round is capable of doing, over penetration doesn’t seem to be high on their list of concerns.

          • FarmerB

            Oh, obviously not.

          • Nicks87

            Air Marshals don’t carry Glocks they use Sigs.

          • FarmerB

            It was a ‘for instance’ – a few poured cold water on the whole idea – whereas my simple example was to show where one might want to use a pistol as a primary offensive weapon and a couple of reasons why. Of course, I never intended to suggest Air Marshall use whatever, it was simply an illustration of a possible scenario – I’m sure there are a whole lot of others.

        • wedelj1231

          If the description of the incidents the 6 second mount was designed for is correct, a user may not have time to notice the loss, switch to irons, and still survive. This is a wild hypothesis I made up to justify a previously existing design, but it may be right.

          • nobody

            >a user may not have time to notice the loss, switch to irons, and still survive

            If they don’t even notice the loss inside 6 seconds then it is unlikely that they are doing anything other than point shooting. Switching to irons wouldn’t take any time at all considering they’re already there and supposedly the red dot generally floats around where the front sight is anyways.

        • CommonSense23

          It was specifically designed at the request of one of the SMUs for a specific task, HR on planes.

        • Nicholas Chen

          Your logic for some reason is not believed by many in the industry.

          Glock and Canik make optics ready pistols. Glock opted to not provide tall suppressor sights like the M&P CORE because the end user might chose a red dot that won’t fit the irons. Much easier to have the end user change them to fit.

          Canik doesnt believe you can co-witness irons so they dont bother.

          • Nicks87

            Target/competition pistols vs combat pistols. Combat pistols need co-witness irons.

        • All the Raindrops

          The T1’S are probably not crapping themselves in the “6 seconds” of engagement that these were designed for.

      • Nicks87

        I don’t know about other calibers but I have almost 10000 rnds of 9mm through my Glock 17 with an RMR attached to the slide and havnt had a malfunction yet (pistol or optic). My RMR is the dual illuminated version (RM08A) and I heard they are a bit more durable than the LED battery operated ones.

    • Nicholas Chen

      Also if you havent shot a frame mounted optic, it is much nicer than slide mounted. I can attest to this. I have shot my M&P9 CORE with slide mounted Jpoint for a year in various action matches and USPSA matches. Now I am running a STI Steelmaster with 90 degree Cmore. It is MUCH faster. Of course there is more going on in my race gun than my M&P9. But shooting the Glock with ALG mount, I notice I am faster.

      • Nicks87

        That is true a fixed mount is going to be faster than a slide mounted optic because you don’t lose the reticle (dot) as much when the slide reciprocates. However they also weigh more, don’t fit in most holsters and add bulk to the pistol profile which kind defeats the purpose of a pistol in the first place. Nothing revolutionary here, people have been using frame mounts on competition guns for more than a few years.

        • Nicholas Chen

          Yes but this was not made for competition. However some people, like me, are going to adapt this for competition use.

          • Nicks87

            Cool, keep us updated on what you think of it. I’m really not trying to trash this mount at all. I just want to know the theory behind it and who, if anybody, is using it in real world scenarios. I know people who test this stuff for viability in the world of Law Enforcement but before I recommend something like this mount I need to have more information than this hush, hush batman bulls**t.

  • PeterK

    Boo! Why not fit the compact glocks? :p

    • G0rdon_Fr33man

      Because then it would not be compact anymore.

  • I like the look of this mount much more than the original, which had a sort of “launch ramp” type metal protrusion in front of the optic. This version is much cleaner.

    • Peeholestinger

      The front ramp on the original is removable. It also functions to prevent hot bits of metal and gas from damaging your optic lens. A fairly important piece if you enjoy clear optics.

      • Interesting, does that apply to non-ported pistols as well?

        • Nicholas Chen

          Yes. You can try it without it but if you see debris and muzzle flash fogging up your optic, then put the plate back on.

    • Nicholas Chen

      What Peeholstinger said. If you look at open division race guns, like STI or SV Infinity, the optic mounts usually have a blast shield.

  • John

    That was a blast shield?

    Isn’t the Glock frame designed to flex. How stiffing up the frame effect the gun, good or bad??

    • milesfortis

      It works just fine.

  • Ron

    wish they would make one for the 20-21 or the 19-23-32 frames

    • Nicholas Chen

      Funny you mention that. I am doing an article on the Six Second Mount. I asked ALG if it will fit on a Glock 21. They said no. I got one anyway so I can use it on my Glock 22 Gen3 frame or my Glock 35 Gen 4 frame. While I was at Big 3 East, I tried it on my Glock 41 (Glock 21 frame) It fit. The fit is a little tighter and it marred my frame just a little but it works. Here is a pic for proof.

  • TheNotoriousIUD

    Delta uses Glocks, right?
    They shoot up a lot of fuselages.

  • DIR911911 .

    am I the only one wondering what the tsupid gold thing is ? and why is it there?

    • Nicholas Chen

      That is my PKDesign Labs pen. I was using it to prop up the pistol.

      • El Duderino

        And here we all thought it was the dumbest AR rifle buffer ever. Nice.

  • Dracon1201

    If they make a G19 one, I’m in.

    • All the Raindrops

      I believe I’ve seen one on a g19

  • Vizzini

    I don’t know if anyone noticed, but I think there’s a Glock buried under all that crap.

  • Don Ward

    Now all it needs is a CO2 tank on the back to complete the this looks like a paintball gun camouflage scheme.

  • Nocternus

    At least with the slide mounted optics you can use most holsters. What are you suppose to do with this thing when it isn’t in your hands?

    • Nicholas Chen

      There are a couple of companies out there that will make a bespoke holster for this set up.

      Off The Grid and Raven Concealment are two that I know of. ALG Defense also mentions a Lions group that I am not familiar with.

      Here is a picture of one made by Raven.

      • All the Raindrops

        Looks like the millennium falcon

        • Nicks87

          It might as well be the falcon for how big it is. They must have used a whole sheet of kydex for that monstrosity.

  • milesfortis

    I am constantly astounded by the number of people who TFB has as regular readers and commenters who are the past masters of hostage rescue personnel.

    It’s a testament to their professionalism that they know so much about hostage rescue Tactics, Techniques and Procedures that they can expertly adversely comment about Special Mission Units that have, literally, spent decades perfecting the near impossible task of Hostage Rescue Assault and are refining it on a continuing basis.

    I wonder why they have never contacted the military, so their expertise can be passed on?

    Seriously, I really can get them in contact with this particular SMU. I know they actually would like to use any expert knowledge base so they might be better able to develop better tactics.
    Oh, I almost forgot: /sarc.

    • nobody

      Someone bought the marketing, hook, line, and sinker. I’ll defer to the knowledge of these operators when this company shares who the operators I’m supposed to defer to the knowledge of are. I will not however defer to ALG’s marketing department.

      • milesfortis

        Personally, I couldn’t care less if you buy into ‘marketing’ or anything else for that matter. Buy the mount, or not, at your discretion.
        To me, what TFB did was a fairly decent job of showing what’s on the market these days.
        Just because you seem to be incapable of figuring something out, or are simply being deliberately obtuse, why should ALG cater to you, or anyone else here for that matter?

        This mount was not a Geissele design ‘out of the blue’ that they sold to someone. Just the opposite. They made it per a request. All they’re doing now is putting it on the market to recoup their tooling investment. Too bad that this capitalistic technique seems to get you all lathered up.

        Somewhere in the vicinity of 5 minutes, at most, of online research will find you useful information. Then you can figure it out for yourself who the end users are, just like ~ 99.99% of the rest of the readers probably have already done.

        • nobody

          >why should ALG cater to you, or anyone else here for that matter?

          Do they want to actually sell their product?

          >This mount was not a Geissele design ‘out of the blue’ that they sold to someone. Just the opposite. They made it per a request.

          According to their marketing department.

          >Somewhere in the vicinity of 5 minutes, at most, of online research will find you useful information.

          No, you won’t. All the articles are pretty much the same and don’t actually say who this group that requested this is or provide what they do in detail.

          • milesfortis

            Well, I’ve got phone number for you to call: 1-800-Cry-Baby.
            You’re proving yourself to be no more emotionally, or intellectually developed than a petulant 3 year old who’s holding his breath and stamping his foot.
            Have a very SF day.
            Oh, and go call Bill Geissele a liar to his face, like a man, not behind his back from a ‘guest’ Disqus account.

          • nobody

            I’m sorry, I didn’t quite catch that. Could you remove Bill Geissele’s member from your throat before talking?

          • milesfortis

            Thank you for again sharing your juvenile intellectual development with everyone.

          • Nicks87

            Oh, come on, don’t be so dramatic. If his company is going to make these claims then they should provide more information. Not just “Spec ops uses it and so should you!” To me that sounds like they’re catering directly to the low IQ mall ninja type customer. They can say who without compromising identity’s, tactics or national security so I don’t see what the problem is. By the way I Emailed ALG when the 6-second mount first came out and I have yet to receive a reply. So who’s the one with integrity issues?

        • Nicks87

          “Somewhere in the vicinity of… …99.99% of the rest of the readers probably have already done.”
          Tell us who then? Or point me in the right direction. And don’t say CAG because that’s a dead end as well.

          • milesfortis

            You know Nicks, I’ve got several ways I think about this and you.

            Mostly, and I repeat mostly, not entirely, I see your comments around here as nothing more than mudballs thrown for the troll effect. And your previous ‘Shut The F**K Up’ doesn’t really make me amenable to helping you out either. And my you do seem to have a thin skin when it comes to taking, as opposed to dishing it out, since ALG didn’t deign to answer your Excellency’s electronic missive.

            So, I’m really not sorry that I can’t, not won’t, literally can’t, help you since you’ve gotten yourself twisted up to the point you don’t even believe yourself.

            You have a very SF day too.

          • Nicks87

            So you are saying you don’t know? I’m confused.

          • milesfortis

            Well I wouldn’t want you to be confused. Frustrated maybe, but not confused.

            Here’s a principle you’ve heard another way in your cop world: Believing something is one thing. Having it confirmed is something else.

            I know – precisely – which unit designed this and had ALG make it.
            But since no one else concerned has confirmed anything, it’s not my place to do so either.

            All that means is, I guess you’ll just have to learn to live with disappointment.

          • Nicks87

            You are right, you win.

          • milesfortis

            Your technique of insulting is better when you just keep it to “Oh, that’s just BS” and “Shut The F**k Up”, otherwise all it comes off as is sour grapes because no one believes your high and mightiness.

            And of course, I see there’s other people around here who’ve also come to the conclusion your personality most closely resembles an unlimed outhouse. And, no, they ain’t my sock puppet.

          • Nicks87

            Sour grapes? Maybe you should go back and read some of your own comments. I’m sure it’s just a coincidence that your avatar name is the same as that pathetic website. In the future please learn how to have a civil discussion with people on the internet, stop pretending to have inside info on matters you obviously know nothing about and have a nice day.

          • milesfortis

            One, I should read my posts for Sour Grapes? I think you need to crack a dictionary. I’m not the one who’s loudly proclaiming that Geissele is putting out “BS” just because your curiosity and demand for answers isn’t being attended to.

            Basically all you’ve been constantly spouting about anything Geissele is: “Geissele/ALG won’t tell ME! Aauugh!!, like you’re something special. I’m laughing my ass off.

            Two, A real simple point for you here. Civil you say?

            YOU stop telling people to “Shut The F**k Up” from the safety of your comfy computer desk chair (I figure you do it from there because you know the health consequences of doing it face to face) when they have a different set of facts than you and you might, possibly, get some – civil – respect.

            But me? I’m nobody special, just a retired federal civil servant who’s last unit was under the administrative control of USASOC, and I have no control over whether you believe that or not.
            But again, you have a very SF day.

  • JaredN

    It is unfortunate that the mount requires that you remove the rear sight. Thus the gun must be dedicated to use with the mount.

    • Nicholas Chen

      You can put the rear sight back on. But it would be pointless. You could not co-witness the irons.

  • Custom holster I imagine.
