I have experienced at least 3 light primer strikes with the same ammo. Sorry Ill have to check the ammo can later but it was .55 grain remington bulk FMJ, don't recall the exact model. I may have had one with norinco yellow box too (pretty sure that was it) but that can hardly be blamed on the gun, I should give my head a shake for even sticking that garbage into this swiss watch but oh well. To be honest I have had light primer strikes far more often with the TAVOR-7 using surplus portuguese ball and another boxed surplus round than I have had with the APC (not sure if the TAVOR-7 is set up for commercial primers only it shouldnt be) I like shooting this gun and the ACR DMR from the bench. The ACR has yet to malfunction once, costs less, but its a brick (even heavier than the APC). If I had to choose between the ACR and the stock APC with the OEM butstock .... It would be a tossup. I never appreciated the soft recoil impulse (this thing doesn't move on the bench) until I shot a G36 right after lol. Im not saying 5.56 has a lot of recoil but man is there ever a difference between some guns shooting the same caliber. I hardly shot this gun for over a year since getting it because of my intense hatred of the OEM stock. Too short, too low. If you have one of these guns put on the (dan Haga?) conversion block and the ACR folding stock. Yeah not cheap and it sucks to spend more money on a gun this expensive but I was at the point why not do something so I can actually like shooting it? Now I love it, feels perfect.
Someone posted this is an AR-180 for 3x the price. No, no it is not. It is only the similar in that they are both semi auto 5.56's. The quality of craftsmanship is not comparable. Handle both. Shoot both. I have. Then decide if they are the same.
