  1. Favorite handguard 5 Star Review

    Posted by on 25th Jul 2016

    there just isn't enough138 i can say about this handguard. it my new favorite handguard hands down. the only issue i found is when trying to use the Superlative Arms piston kit the gas block is just to wide. when i compared this to the BCM KMR i noticed that on this handguard it is a slightly narrower channel for the gastube. it's just enough for my piston kit to not work. but that is not the hand guards fault. I have 3 of these and they are great. you can get them in either mlok or keymod which is my preference. but you cant go wrong.
