Brownells AR-15 Hammer Drop Block

Brownells AR-15 Hammer Drop Block Features The Brownells AR-15 Hammer Drop Block solves a genuine problem faced by armorers and gunsmiths who need to test trigger pull and hammer fall on an open AR-15 receiver. Without a block in place dry firing an open lower risks the hammer striking the shooter s thumb or slamming directly into the magazine well wall which can damage both the receiver finish and the hammer face over repeated use. The shock-absorbing Delrin construction cushions that impact protecting the gun while still allowing an accurate feel for trigger pull weight and travel. This makes the tool valuable for evaluating aftermarket trigger groups before final assembly. Made from solid black Delrin the block is sized to fit directly into the magazine well of a standard AR-15 lower with the upper receiver open or removed requiring no special tools to use. At roughly 3 inches at the top and 2-3/8 inches within the mag well with a height of 2-3/16 inches and a width of 7/8 inch the block is sized to sit securely in place during testing. This is a simple inexpensive tool that belongs in any serious AR-15 armorer s kit saving both the shooter s hand and the rifle s hardware during repeated trigger evaluations. It is a practical accessory for anyone who regularly builds tests or repairs AR-15 lower receivers.
