I decided to take my CAI(ugh...I know, I know) FAL out monday for a little practice. I loaded up 3 magazines and barely got through 1. The gun repeatedly stovepiped, and failed to fully seat the round. It luckily is the "good" CAI with the correct feed ramp. I never had this problem before the new magazines, and new DSA Scope mount. I did notice it would feed single rounds better than from the magazine. If I pop the slide release, it would pull a round from the magazine and chamber it 2/3 of the way. I also can't figure out how to clean/adjust the gas system It has a grenade? launcher site on the front that I can not figure out how to remove. Do I have to have the wrench to adjust the preasure?
