Amazing Value, Superb Staking, Get it !
This BCG is absolutely the best value on the market in my opinion, especially with free shipping and no sales tax outside of Texas. The chrome application is very nicely done. It is not as smooth as NP3 but it is more durable and far less expensive. Don't get me started on the staking, its a thing of beauty , it is perfect , SERIOUSLY. Better than my Centurion & BCM. The Cam-Pin fits nice and snug too. Better than my JP Enhanced bolt. As of this writing , the following info is not listed on this webpage: The gas key is sealed with Permatex/The Cam-Pin is made from 4340/The Extractor is made from heat treated 4140 which is almost nearly as good as 4340. If they add the cryogenically processed Sprinco Gas Rings it will be even more complete. But make no mistake, this thing as is , is in all likelihood best deal on the market , nothing comes close in my estimation . 140 bucs for a chromed Microbest with Sprinco springs and Ocks screws is just WILD . This is the way.
