Yes they do. Awesome product selection.
@Country Bread, you need an "enhanced" AR firing pin for reliably firing steel cased 7.62x39 ammo. The primers in the imported rounds are harder than typical primers. http://www.blackriflearms.com/AR-762x39-Enhanced-Firing-Pin_p_9.html My left hand BCA 7.62X39 upper goes bang with every trigger pull. I replaced the standard firing pin that came with the upper with an enhanced firing pin when I built my rifle. If you use domestic commercial ammo, the primers are "softer" relatively speaking and will go bang with normal firing pin. Good luck! @Richard Pincelli, I use these mags for my 7.62x39 AR: http://cpdmags.com/762x39-magazine/ They feed nicely and work well. Good luck!
Not awesome I have an AR 15 that shoots the 7.62x39 I had it 5 months, it has messed up twice, same issue light primer strike and Scott's tactical where I bought it don't wanna fix it and I can't get anyone at bear creek arsenal won't pick up the phone.
