Feeding/Cycle Issue
I was able to take my new Bison Armory 18" SPR in 6.8. I shot 2 different factory rounds. 110 Hornady Vmax and 85 E tip by SSA. The Hornady feed and cycled with no problem. The SSA did not feed from magazine or even cycle. I would have to pull charging handle to extract round or when I shoot the round ejected but another would not feed and go into chamber. I emailed Bison Armory and called about the issue. From what I could find it could be magazine related or gas related. Just weird how the 110s were fine and the 85s were not.
