The Umarex 577.20.07.0 is a genuine replacement disconnector wiper for the Umarex Heckler & Koch HK416 .177 CO2 BB air rifle. The disconnector is part of the trigger mechanism that resets the trigger bar after each shot and prevents the gun firing until the trigger is released and pulled again; the wiper is a small internal component that seats against this part to keep it moving cleanly. Over time and heavy use, wipers and small internal trigger-group parts can wear or lose fit, which shows up as a stiff, sticky or unreliable trigger action. Fitting a genuine Umarex replacement restores correct engagement to the manufacturer's original specification. This is a small internal spare, sold individually, and is intended for owners and workshops servicing the Umarex HK416 CO2 BB rifle rather than for general retail display. As with any trigger-group work, fit strictly to the manufacturer's part diagram and take care with CO2 safety when the rifle is disassembled. Genuinely useful to have on hand for anyone maintaining this air rifle regularly.
