From Strike Industries:

The Strike Industries AR Modular Magazine Release (MMR) offers a quick and simple way to configure your mag button preference to one of three (3) included options. No need to remove the mag catch if you want to change the button. A simple push of the magazine button adapter using an object that fits in the space allows for a quick and simple swap of the magazine button.


The SI MMR comes with included Standard, Extended and Oversized buttons so you always have the modularity to swap at home or at the range. The mag buttons are textured for positive feel and manipulation of your AR for enhanced ergonomic control. The provided mag buttons are made from lightweight polymer paired with SUS630 stainless steel shaft sleeve and mag button adapter. Included as well is a steel magazine catch along with a magazine spring to give you everything out of the package for a drop-in installation.

    • Same with mil spec triggers, but those aftermarket ones are really nice. I own two geissele triggers, but I’m cool with not buying anymore. It is nice having ambi controls though, and quicker. Takes a lot to get used to especially if you aren’t using them regularly or for duty purposes.

      • I’ve looked at “drop-ins”, and really couldn’t justify getting one…
        After carrying an M16A(pick your flavor) for so many yrs, my hands just know where to go for whatever needs getting done…

        What people should be concentrating on is clearing malfunctions, using S.P.O.R.T.S.(immediate action) or remedial action…train, train, train…practice, practice, practice…
        Too late to think about it when you need it….

    • Same. The only upgrades I’ve performed to the innards of my ARs are polished triggers and JP Rifle buffer springs for smoother cycling (someone here at TTAG recommended them to me a few months ago). Otherwise all parts are as received from the mfrs.

  1. Might be good for we range toys, but I’d rather not use polymer on my “duty AR”. Which is odd, because all my pistols are polymer lol. I haven’t abused any of my ARs like during deployments, but I just can’t use polymer on them, aside from the grip I guess. Fixed front sights, metal foregrips, and lights.

    • That plus poly lowers vary slightly from mfg to mfg. I have several different types, and unique over-molding on stress areas makes designed-on-aluminum-lowers aftermarket parts problematic at times. I have been disappointed in the past.

  2. im from the school of “the mag release should work well but not *too* well”
    just like the bolt catch:
    only one paddle on it please
    no ambi safeties either thank you
    im pretty basic…just a slightly oversized charging handle latch a decent trigger a solid optic some 45 sights a streamlight and 28 in the mag and im gtg

    • Yep. Slightly oversized charging handle, reliable light and sights/optics. 30 in the primary mag and 29s as the backups.

  3. I don’t see the need for a “quick change” modular design. It takes about the same time to unscrew a release button and screw a another one in place as it does to mess with these tabs using a little screwdriver, and the old fashioned method is more secure.

  4. $35 for a a mag release with a polymer button options seems pretty steep. If all the buttons were metal I’d be tempted to buy it just because I’m nerdy like that.

  5. So what actual point is there to this? I’ve never felt the need to swap the mag release (or really any part) on my gun “on-the-fly” I just pick the one I like best, stick it in there, and leave it there because it is the best to me so why the hell would I want to change it for something that’s not the best?

    What specific missions could you accomplish with one style of mag release but not another?
