Not bad... - Mantis Blackbeard the Auto-Resetting Trigger System for AR-15

Four things that I have noticed: 1. This fake "bcg" doesn't let your hammer rest in the normal, vertical position. So, if you don't use this for some time, then, I suggest swapping this with a real bcg to release the spring tension on your AR's hammer. 2. It was not sighted in at the factory. IDK if it was only my unit, but the laser was shining on the rifling inside my bore when I first got it. 3. This "could" be used as a bore sighter; because there's a little switch to keep the laser constantly on. 4. The "mag" battery charges very slowly. 0-100% took around 15 hours!
