I have had mine for a couple of years now and worked through most of the pecurarities of this weapon. Now this. rifle will not cycle a new round from mag into chamber. Gas is set right. Rifle fires and bolt goes back & back into battery but does not pick up the next round. Does this with the mag that came with it and also does it with the two aftermarket pmag FAL type mags I bought for the weapon. This is a new thing I have put at least 1000 rounds through it and it does it with all different weights of brass cased ammo I tried. Suspected the mag but all three of them? Another thing, I can manually cycle the bolt and fire rounds all day long no issues. After a session I always take it all the way apart and clean it up, but have no idea what I could have done putting it back together if anything. Any help out there or anyone have this issue and solve it? Again, I know it is not a gas issue.
