Good quality - Radian Weapons AR-15 Extended Bolt Catch

Like a lot of things radian makes, this is a great as well. Just the right size, super easy to find and press or just smack it to release. Hold open is just right too, not too big that it can be accidentally tripped but still easy to find and use. Still much better that milspec and also doesn't get in the way of the hammer pin. Also doesn't get in the way if you use a mag linked double pmag, can still actuate it fine. Easy to install as long as you have the right roll punch and a starter. Comes with a spirol (coil) pin. For the price I wish they had thrown a spring in with the pin
