[SHOT 2016] Knight’s Armament SR-25 E2 ACC M-Lok

IMG_0669

I had to visit the KAC booth while I was at shot to see if I saw anything cool enough to share with you guys. Turns out they are now supporting M-Lok on the SR-25, thankfully they let us take some photos. The Knight’s SR-25 E2 ACC M-Lok features high end components like a hammer forged barrel with 5r cut chrome lined rifling and their own proprietary no bend gas tube that is not roll pinned into place. Knight’s uses a flared end similar to a brake line on a car to prevent gas leakage and ensure a connection that will not weaken over time. The MSRP is a bit steep at $4861 but for that price you get the same quality rifle that is issued to the military. Same build quality, same testing, same craftsmen, same everything.

The Knight’s SR-25 E2 ACC M-Lok on display had a Knights QDC Coupling flash hider mounted to it so that you can mount their incredibly tough 7.62-QDC-CQB can to the rifle. The rep I spoke with told me it was the lightest and smallest combat rated can currently available. Sure, it might not be the quietest can on the market, but to reduce the sound signature just enough to make a marksman hard to locate it is perfect. I know that the few bits of KAC gear I own are all overbuilt, the rifle and can that I had the pleasure to handle are no different.

    Any idea if this is the rifle submitted to the CSASS trials?

    • Patrick R.

      No idea.

    • Uniform223

      Aren’t MARSOC guys using something very similar to a SR-25 EMC?

      • Joshua

        They procured the K1 upgrade kits to augment the M110 to replace the SCAR platform.

        However I’m not sure if it in its baseline M110K1 design would match the CSASS requirements.

        I could be wrong as I haven’t actually read the requirements.

      • Joshua

        Just had a friend confirm this is not the rifle submitted. Also said the EMC was given the go ahead in 2015 for the Army.

        • Uniform223

          cool beans. Also I found this interesting little tidbit

          http://soldiersystems.net/2016/01/22/shot-show-hk-g28e/

          • Joshua

            Saw that one. No surprise the HK was down selected, however I don’t see it winning.

          • Joshua

            Also found out Remington submitted a version of the GII, which is actually exciting to see how well that platform performs.

  • TheSmellofNapalm

    Thanks for the writeup, man. In my opinion KAC’s building the best rifles on the market right now. The ACC is a beast, I wonder how well it can group when compared to its stainless steel brother the APC. Chrome lining seems better for a long-term combat environment, so I really hope an ally (or PMC) adopts this. My guess is they won’t be disappointed.

  • The king

    Nice stuff but like always, the most over priced out of them all for nothing earth shattering. One of these years maybe they’ll get in line with other more reasonable makes like Noveske or DD.

    • TheSmellofNapalm

      Maybe one of these years Noveske or DD will win a contract.

      • JumpIf NotZero

        Noveske is gone.

        • TheSmellofNapalm

          I know lol, don’t tell me 🙂

        • iksnilol

          Seriously? What happened to them? I know Noveske (the guy) died, but what about the company itself? Is it going down the crapper?

          • Joshua

            Noveske is fine, but they don’t have the manufacturing capability for government contracts like these.

      • Joshua

        DD won the RIS II contracts and has a lot betting they will win the M4A1+ ancillary overhaul contracts.

  • Uniform223

    $4861 USD a bit steep? Though they make some really good stuff, I believe at one point you’re just buying the brand name.

    • G0rdon_Fr33man

      They sell to military. Off course it is overpriced. That is the name of the game.

      • Patrick R.

        My understanding is they can not sell it at a lower price as a result of the contracts they have. That is hearsay and may not be true, but that is the rumor flying around.

  • G0rdon_Fr33man

    lol, photographs being ITAR restricted… I get the feeling “not for export” is used for marketing these days.

    • Patrick R.

      No, that is a very real sign. I was asked to stop photographing until the media guy came over who happens to be a friend of mine. Only with his permission was I allowed to continue.

      • JumpIf NotZero

        This is untrue. It’s phony marketing that KAC has been doing for years.

        There is nothing in their booth specifically that isn’t also available in other booths with no photo issues.

        And if it was an ITAR issue, then saying “yea ok blogger, go ahead” isn’t an indemnity or any sort of permissible exception.

        This is nonsense.

        • Patrick R.

          As I said. The only reason I was allowed to continue is the media guy happens to be a personal friend of mine. They sent several media members packing while I was taking photos.

          • Stan Darsh

            That is referred to as “Cartmanland Marketing” and is in the same arena as Neg Theory.

          • Patrick R.

            Off to the Google!

    “hammer forged barrel with 5r cut chrome lined rifling”

    Um……what? So it’s hammer forged, but cut rifled? And they use a match grade rifling (maybe), and then they proceed to ruin whatever accuracy gain there is by chrome lining it? At this point you’d be better off using the money to wipe after using the can, since sure as hell KAC doesn’t know what to do with it.

    • Joshua

      This isn’t a sniper rifle. It’s a battle rifle similar to the Mk17.

    • Uniform223

      Though I am not enthusiastic about the price…

      *sarcasm on* what do these guys know about making a military grade semi-automatic 7.62x51mm DMR or sniper rifle? After all they made the much failed SR-25 used by special forces units the world over and the M110 SASS for the US Army and USMC. A chromed lined barrel? Really?! Still they met the performance specifications put out by the US Army of 5 round group at 300 feet no greater than 1.1inch with M118LR ammunition suppressed and unsuppressed. Surely Knights Armament Company is a bunch of amateurs that don’t know what they’re doing. Why don’t you go down to Tutisville FL and show those guys how its done because clearly you know more than they do… *sarcasm off*

      • Scott Wagner

        So, first off: They pulled a 1MOA group with match ammo. For the amount they’re charging, they sure better be able to do that.

        And please, read the technical specifications again. My point is that they make no sense. If there barrel is hammer forged, it isn’t cut rifled, since the entire point of hammer forging is to have a consistent barrel to barrel rifling, and not having to remove any material. The sentence I quoted reads like a random buzz-word salad to people who are actually in the industry.

        Now, in all fairness, on KAC’s website they make no mention of hammer forging, and merely say that it’s a cut-rifled chrome lined barrel (which, personally, I think is a waste of money given the inconsistencies of chrome lining, and that they’d be better served by actually hammer forging the barrels in this instance…).

        Personally, I’ll never buy a KAC gun. Their ego’s are too big for the guns they’re making and the price their charging. Poor CS experiences with them trying to help customers, combined with the exact opposite from LMT (who bend over backwards to help in my experience), mean that even if LMT *wasn’t* getting a bunch of military contracts, and *wasn’t* the most common choice from guys I’ve talked to from units that are looking for non-issue replacements for their old and maintenance heavy M21s and M25s, they’d still be (and in fact, were) the ones to get my money instead.

        • Uniform223

          so this is all a personal take on it… looks like bias to me.

          • Scott Wagner

            Yes, I’m biased against buzz-word-salad. Where do I say anywhere that my beef with KAC is anything *but* personal?

          • PatsFan

            Of course it’s personal, but thanks for letting us know it’s personal to a moron talking out his a**.

        • TheSmellofNapalm

          Keep crying. Modern SR-25s have been tested to 5,000 rnds suppressed with no cleaning. The SR-25 has continually beat out all competitors in military trails. That is not by accident. If it wasn’t for KAC NONE of the other manufactures would have anything.

          Their SR-15s can run for 20,000 rnds without any cleaning as well and still group ~1 MOA, I suppose you’re going to bad-mouth them next. You’re gonna need a little more than barrel forging discrepancies to discredit Stoner’s Rifle, which is what these are.

          • Scott Wagner

            Wow. Chill dude. Where have I said they make a bad rifle? Whoever the writer of this article was talking to, or the writer themselves fell into a trap of buzz-word-salad, which I even point out isn’t there in KAC’s actual literature. I don’t like the idea of paying for cut-rifling if it’s going to be chrome-lined, personally, but again, that’s a personal preference based on my own experience with barrels.

            As for the “continually beating out competitors”. For the M110 program, they were up against, what, DPMS/DSA/Remington? That’s….not that high a bar to pass. Also, they *didn’t* win out against LMT for the L129 program for the Brits, and I don’t think they were in NZ’s recent trials for new DMR and AUG replacements. In fact, a quick and dirty search shows that the only time LMT and KAC have really gone head to head (and I don’t know of any company that could honestly join those two in a compitition for a military sniper rifle of that basic spec), was the Brit L129 program. If you’ve got data that indicates differently, by all means, I’d love to see it.

          • Uniform223

            It is my understanding that KAC did not enter into either solicitation by the NZDF’s new rifle and/or the British L129A1. However the L129A1 DOES have KAC rear and front sights

            last year that rifle was put on display at shot show… its featured towards the end of the video.

          • Scott Wagner

            I can’t search right now, on a phone, but the only info I’ve found about the L129 acquistion was that LMT beat out products from KAC, HK. And a few others.

            Re NZ trials, I know they didn’t enter the recent 556 trials at all, but kind of like the L129 trials I haven’t found anything so far on the actual trials, only the results.

          • Uniform223

            Most sources I have found (because I am on my computer) list H&K, FN, Sabre Defense, and Oberland as the prime contractors of the competition. The only place that I have found that mentions KAC as a competitor was Americanrifleman.org.

            http://www.americanrifleman.org/articles/2011/3/18/britains-l129a1/

            The article mentions the difference between the L129A1 specifications and requirements differing from the SASS (Semi Automatic Sniper System) for the US Army. The M110 SASS required the weapon to fully take advantage of and use match grade ammunition. This would make the M110 inherently more accurate than the L129A1 ( I think ). The L129A1 on the other was designed from the beginning to be a DMR dedicated rifle within the squad that was meant to fire the very common NATO 7.62x51mm. So maybe it wasn’t because KAC didn’t make a good product. Perhaps the product that they offered was essentially a shorter barrel M110 (like what the US Army is looking for currently).

          • jono102

            The LMT .308 DMW(MWS) was initially purchased by the NZDF as a UOR (Urgent Operational Requirement) for use in Afghanistan. LMT was the only outfit that could produce the complete package and numbers the NZDF wanted in the given operational time constraints. The DMW role/capability was later identified in the Infantry and the LMT was selected as it was proven and already on limited issue. An updated version was then adopted.

        • PatsFan

          Okay, thanks for posting. Now we know you’re talking from your a** because you can’t afford their products.

          • Scott Wagner

            *sigh*. Again, I don’t think, and have never said, that they make a bad rifle. You’re a KAC fan-boy, I get it. I don’t mind that, since I’m an LMT fan-boy. But you’ll notice I haven’t said KAC makes anything that’s bad. Hell, I run their bipod on my LMT, and if I was going to run irons, I’d run theirs. I don’t think their rifles are worth what they’re asking, and I don’t like the attitude that pervades KAC as a company based on various interactions with them, but their product is good.

    • TheSmellofNapalm

      They also make an identical rifle with a stainless barrel, in case you were feeling super smart or something.

      • Scott Wagner

        And a 5r SS barrel is amazingly accurate. But hammer-forged it wouldn’t be 😉

  • JRo

    Dear KAC,

    Please release the URX4 MLOK rail to the public.

    Sincerely,

    The Public

    For 4,800 I’ll build 8 rifles on my own bench…no thanks! 🙂
