Received the 2A Armament BCG,very well made. Smooth,adjustable & lightweight. Adjustment screw on the side makes gas adjustment very fast & easy! Optics Planet has the best prices too! Make sure you have a t-6 torx to adjust the screw with.

A amazing bolt design that I wasn't sure would hold up because of its finned aluminum base Its made so nice and the little tune gate really helps and so super easy to tune. I could get spoiled because it really is better than those dang long tools you have to use. Makes it faster to tune supressed. It was nice to tune the ejection just right and it has almost no recoil. It takes getting used to how fast it can follow up shots. It's so light you can feel the difference between a regular full mass and this bolt and it is fairly noticeable. Im much more accurate with it since it cycles so quick. Im not sure of longevity but it has worked flawless for me. It was worth the cost and lightweight tunable features. 2A makes such nice parts.
