I am very happy with my decision on the BCM low profile gas block. The quality is amazing, and very easy to mount. I also dimpled my barrel, to eliminate the chance of the gas block moving. I really like the mounting hardware that came with the gas block.

Fit was outstanding very tight allowing for a great seal. Nobody beats BCM for order processing and getting your items shipped.
nice tight fit
Wanted to have a more comfortable and hopefully lighter AR . Just more enjoyable too shoot. replaced the hand guard, BCM gas block and added a MFT stock. Much easier too shoot and went form a 7.5 + pound gun to 6 pounder. Feels solid and did not get too hot even after 200 rounds in 1/2 hour. Nice product, excellent engineering.
This is the second bcm gas block I’ve used, love it. Works and fits perfectly
Perfect fit and finish.
Easy to install.
Works great.
Mates well with the barrel. No gap, or random spacing. Sets properly, makes installation a breeze.
