Feets / Collection / My build Q and SBI

Mini fix 16” 300 blackout, Reptilia custom receiver mount, khales k16i 1-6x lvpo, Atlas bipod, cherry bomb, whistle tip.
SBI St-22 12” barrel, mdt walnut grip, eotech 512, slingster 2.0 sling.

Shot the mini fix for the first time yesterday. I shit you not bullseye @ 100 yards with the cheapest plastic cased 300 blackout barnes ammo on a cold bore shot. Part dumb luck part fixit sticks for proper torque and that direct mount? I’m not experienced only had pal a few years. Anyways wish I got a inch pound torque kit before I got my 4th rifle 😅

SBI St22 is running like a dream with any ammo in BX mags.

Still working on the kinks of the Tuff 22 mags. Any tips would be greatly appreciated. I’m thinking loading the mags and leaving springs under pressure for a week or two. Maybe polishing the metal feeding lips or filing em down…? Strategic tape for better fit angle? I will not give up until this is solved.

Is it hitting low and crushing the round? Or just skipping over the round all together?
