Description

Have you ever been shooting your new AR at the range and failed to attract any attention?  Tired of the shoulder breaking, PTSD inducing recoil on your AR15 or other 223/5.56mm rifle?  Tired of expensive, overweight muzzle brakes ruining the balance of both your otherwise svelte 3 gun rifle and your checking account?  Well, there is now an affordable solution for you:  Our A-Hole Mk 4a™ Muzzle Brake.

We start, as we always do, with high quality, domestically produced 6061-T6 Aluminum so that weight stays low but service life is still excellent (3000+ rounds).  From there, we add our propriety A-Hole Technology™.  What is this you ask?  Through a combination of late night guesswork and non-hipster related irony we slaved away to create an effective and audibly recognizable port design.  Our A-hole technology allows muzzle blast gasses to be harnessed to help eliminate recoil and keep you on target for faster follow up shots, better split times and gain much, much more sex appeal.  No science or animals were harmed in the development of our A-Hole Mk 4a™ Brake.  To aid with installation we include a shim kit.  Yes, that’s right, a shim kit.  No crush washers, peel washers or some other, lesser method for timing your muzzle brake to be found here.  Just a sweet, made in America, reusable shim kit.  Our A-Hole Mk 4a™ Muzzle Brake was designed for the shooter that is very weight conscious with their rifle, for the competitor looking to ditch some weight at the end of their rifle or for the guy who just wants to let freedom ring to all with in earshot.

 

Silence is golden, duct tape is silver and loud guns are for A-Holes.

    This thing is mean! I revied this bad mamba jahamba on my youtube channel and yeah, it mitigates recoil but boy does it rattle our jaw! For $30 you can’t go wrong.

    Other than the fact that the thin/fine corners at the upper edge of the A-hole cuts seem to deform easily (after just one short outing of shooting) this brake is amazing. It weighs next to nothing and does an AWESOME job reducing recoil and muzzle rise. For the price you can’t go wrong IMO. However the OCD side of me would gladly trade the weight savings for this exact design in steel..

      A steel version is coming soon. We have some other BIG products coming out before then, but steel brakes, AK brakes and 308 brakes are all in the works.

    Tested this muzzle brake over the weekend at the local range. This thing is pretty darn effective. It dramatically improved the feel my AR that I ordered another one(why is this item always on backorder?). Can’t wait for the steel versions, are they coming out this year?

    Does reduce muzzle rise & directs muzzle blast to the sides (out of night time line of sight). Check and Check! From behind the trigger I did not notice the extra noise… officers on both sides said it is loud as F@€K. Looks good, can’t wait to get it in steel.
