Good value - Troy Ambidextrous Bolt Release

Good addition to my AR. I have a vey long 18 power scope,and shoot off the bench.I like being able to control the rifle from the right side,and this bolt release makes it easy.Theres a notch built in to the area that fits thru the trigger guard,and this makes it easy to operate with the knuckle on my trigger finger.I also put one on my 9mm AR which lacks a bolt hold open on the last round fired.When I recock with my left hand I activate the bolt catch with my right on the right side.Much easier.Easy to install.
