Mech Armor Drop-in Match Grade Trigger

RJ35_Trigger_011_1024x1024

Now that I have experienced a “match grade” trigger with my RISE Armament, I am eyeing other manufacturers to see what they offer (like a kid in a candy store).  Along comes Mech Armor with a pretty cheap ($135) drop-in trigger, they are titling “Rough Justice”.

Leave it to MechArmor who designed and brought you the first commercially available, fully ambidextrous, military grade charging handle for all AR style weapons in 2009, to also be the first offering you a Match grade level trigger group for your AR15 and AR10 rifles as well, but at the lowest price in the industry!

Specifications:

  • Single Stage Drop In Trigger
  • 3.0 Lb Pull Weight
  • Complete Drop-in Assembly
  • 100% Made in USA
  • EDM technology for precision Manufacturing
  • All Tool Steel trigger, hammer and the disconnect
  • Heat-treated for exceptional lifetime service
  • Trigger housing machined from 6061-T6 billet aluminum
  • Trigger housing is black anodized for life time durability & hand polished

 

I am definitely interested in doing some comparisons against some of these different drop-ins.  The Mech Armor entry doesn’t list needing a trigger pin kit, but does warn of potential incompatibility with some AR-10s.  I don’t have any experience with their other products–do any of you readers have an opinion?  Rhetorical–of course you do… 🙂

(note: their site has some inconsistencies on prices throughout the text, but the one at the “add to cart” shows $135)

    It looks like a clone of the Timney AR-15 trigger. Also, i would bet that this trigger will not work with .22 lr as well.

    • Don

      Try the the HiperFire HiperTouch line of triggers, they have lightened the trigger pull but increased the hammer fall energy. You won’t have any issues with hammer strikes when using 22lr ammo with this trigger.

    Good on them. I have two SSA-E(s), and also an armalite two stage. Obviously, the Geissele’s are the bees knees, but anything…..and I mean a-n-y-t-h-i-n-g is better than government issue trigger.

    My comment vanished (links probably).

    Looks like another branded Tom Vehr ‘Velocity’ trigger (same specs, etc.). Outbreak Ord. is selling the same ‘branded’ trigger as well.

    • Jack B

      I recently looked at Outbreak, I only saw the POF trigger as available???

  • Iosef

    Yeah, that looks a lot like my Velocity. Bout the same price, too. I’m all for it – availability of the Velocity has been kind of low.

    From what I understand, the only way to make a lighter single stage trigger is to lighten the hammer spring, which is not a good choice. That’s why Geissele only makes 2-stage. Having little experience with these, has anyone else had troubles with this type of design? Note that is lighten, NOT smooth out as in the ALG triggers.

    Only problem I’ve seen firsthand is the trigger pin walking out in a Timney due to the light hsmmer spring.

      It’s not the only way, though every little bit helps.

      Reducing the force required is largely a matter of reducing hammer-sear engagement area, just like they do trigger jobs on 1911s by stoning the hammer hooks lower and lower, and polishing the remaining engaged surfaces as well as possible. This of course can make the weapon more likely to discharge if it is dropped, or so I’m told. It’s also expensive as if you’re doing it one at a time, non-trivial hand fitting is involved, or, if mass produced, non-trivial QC.

      Reducing the power of the trigger return spring helps too, on designs that have them. Which introduces the possibility of an eventual failure to reset.

      tl;dr there is a reason milspec M16/AR15 triggers are as heavy as they are

    • Don

      Try out the HiperFire HiperTouch 24c trigger. They have been able to lighten the trigger weight while increasing the hammer fall energy. And you can adjust the trigger from 2-4 lbs buy just changing the springs without having to remove the trigger. I am using the trigger in four of my AR’s.

      • Jack B

        Or you can just make the next obvious and worthwhile up grade to a titanium pin and you are off.

  • John Daniels

    Lost me at “rough justice”. Just give it a model number, and move on, like everyone else…

    • Jack B

      It appears the model # is RJ30..

    Thanks for the heads up on this TFB, goin to order one now because I already know the company’s commitment to high quality over profit. I learned that when I purchased their TacOps-1 handle for my rig, which then led me to buy 3 more since. And their lifetime warranty doesn’t suck either. Says they will warranty them even if it fails in actual combat or police operations, etc. Old school guys to deal with to, I like that. They actually called me after each sale to make sure it was all good. Who the F does that? Also told me to watch for the new 7075 flip-up sights they are about to come out with for around 89.00 bucks for the set! Said the frnt sight is the HK style.
