super smooth bcg. I found one in a mom and pop in podunk where ever Ville bout a year ago. It quickly became my most favorite. This dude outperforms everyone I have ever had. Def recommend,not because it’s reasonably priced, because it’s the best. Hands down. If anyone says anything different they don’t know what they’re talkin about.

Very nice, very well built. Have not installed it yet but soon. Looks to be a better BCG than my Aero Precision I purchased years ago.

Was having a hard time finding a BCG during the panic buying and came across these. They had just came back in stock so I didn’t hesitate and ordered one….a decision I do not regret. Very high quality craftsmanship. I now have over 2000 rounds through the first one I purchased and it still performs the same as when I purchased it.
