I’ve put 27,000 rounds through mine and never cleaned it, my hair is growing back and I’m dating a supermodel. Thanks RTB!

Seems to be a good value during The ‘Rona. I’d personally pass, as I prefer C158 bolts.

I have 2 NiB BCGs and 1 hard chrome BCG.

They are all awesome for cleaning. They are worth the extra money for that alone.
