Mag extension
I really got this thing for the looks but also so I can stop using the 50 round mags for reliability issues. I suggest getting a better and longer spring for the magazine. I tested chambering a few rounds while full with extra 5 , and the rounds did not properly chamber. I looked at the full mag and pushed the billets down to see if the spring is pushing the rounds out and it was not AT ALL! Other than that is awesome! Will be ordering the compensator here soon!
