An alternative with a great reputation for performance at a fraction of the price. Not saying BCM's are not high quality.

BCM is one of the best companies out there for gun parts they hold up the longest yeah it’s a little expensive but you get what you pay for I recommend buying it it’s pretty pretty sweet

For years these have set the standards that all BCGs are judged by. BCM's has always been on the high side, but many highly experienced shooters, and security professionals have found value in their performance, and high quality. Paying $190 for one of these may not be your idea of a great deal, but it isn't anywhere near as stupid as getting screws out of $150 by PSA, aka JJE Capital Holding for a $50 BCG. I appreciate Primary Arms for not running up the price on these.
