Nickel boron ar9 bcg
I am still building this pistol but so far everything seems perfect. And it looks good too.
USWorks Great
Put it in my Pistol with a 7.5" Barrel. Cycles like a champ.
USNot up to my standards.
Im a machinist so it’s hard for me not to criticize the way things are machined. Product was definitely not the quality I would expect a $200 BCG to be. Fail zero has a great customer service team though. Told me to cycle it through and if any issues happened they would send me out a new one.
