best bolt carrier device there is. I’ve tried all 3 of the major bcd’s on the market. Both the other 2 being either too heavy, or too lightweight. Both being wobbly & cheap feeling. This one is just right! well made to very tight tolerances, but with an overall excellent fit & finish, tightening up an already loose bolt carrier lock. Best $30ish buck part I’ve ever bought!

A very well thought out product, it lines up nicely with the Knight’s Armament ambidextrous mag release as well as Jp enterprises ambidextrous magazine release. I’ve personally used Magpul’s bad lever and unfortunately destroyed it with very mild use. This seems to make up for what theirs was lacking. It’s spaced off the receiver far enough to accommodate anti-rotation/walk pins but not so far that I anticipate any snagging that would compromise function. I would highly recommend this to any left handed shooter.

Easy and quick install. I’ve had mine for a few years now and not a single issue or concern. Helps with quicker reloads but the biggest take away for me is manipulating functions with just your firing hand. Each one of my rifles have them and I highly suggest this product to anyone that does not have one.
