Damn, I probably would have tried one of their 10.5" barrels if I didn't get a Rainier already
Love my Ballistics Advantage 5.45 barrel. I had my Vortex Viper on it to start and I was getting around 1.5 moa 10 shot groups (I'm not that great of a shot). Was pleasantly surprised to see that from surplus ammo.
The IQ of INGO Members delivers!
wsenefeld- did you have any issues with that BA 5.45 bbl? I read of a case of cycling issues with Wolf 60g but Hornady V-MAX would cycle fine.
Thanks.
