Fortress tactical contacted and pre order open warning request email sent, which is supposed to open up per PWS in August w/ a 6-8 month bud time turnaround once pre-ordered.

This is less than ideal, but currently my only plan of action. Been kicking around the build it yourself upper with the requirements I seek. Built a handful of uppers before, just not a 7.62x39 variant. I'm aware of the hard primer issues and firing pin/ hammer spring enhancement and to use c-product mags.

That being said, what are my options for a 7.62x39 10-11in. Side charge (Forward side charge not style would be ideal) piston driven AR upper? I already have a suppressed bren 2 x39 9in which is the reason I've been stockpiling ammo and now hence want to transition from 300blk to suppressed x39.
