Slick and reliable
by Matthew
Put around 900 rounds down range with this BCG in winter, left it bed of truck from Ohio to Indiana in winter for about 3 days. Took it out to clean, everything slid right off. Super easy to clean.
The best bcg
by David Drago
The quality and precision in this BCG is phenomenal. I have 2 already and going for a 3rd. It’s super smooth and has a natural lubricity from the quality of the finish. Chambers nice with a FN chf or noveske chf barrels and you literally can wipe it clean after hundreds of rounds. I can feel the difference on the performance of this bcg and is better than that $350 nano g or lantac or any of the many others I own. The operating temp it can handle should be an eye opener alone. You’d probably burn up and melt your gas tube before you could damage it. IMHO reliability, easiest maintenance, superb performance…. KB did a review on these a few years back and the tolerances were all real good and everything is to correct dimension

I own two of these now and I love them. I takes just a few minutes to wipe down and clean after a day at the range. So far they have held up to everything I have thrown at them.
