Old Bushmaster, Stag and a Frankengun, all 1 in 9. All shot 55gr sub moa.
JP springs and a set screw to remove some creep helps.
Non free float, two were xm177 style (heavy bbl under handguard,11.5 +5.5.
Both chrome lined.
None were pencil or M4. The other was a medium 16.
Sounds pretty damn good. I don't remember seeing those entries in the black rifle challenge. With shooting like that, they should be entered. Was that with iron sights? I almost busted the moa barrier with my Noveske tonight with iron sights...
