Hiperfire PDI AR-15/AR-10 Drop In Curved Trigger

PDI stands for Power Drop-In. This single stage AR trigger gives a 2 lb pull while keeping a mil-grade hammer strike, so light primer strikes are not part of the trade. The black nitride finish feels smooth, resists corrosion and has a polished look.

Hiperfire built it to survive blowback PCC use too, with a hammer collision bumper plus disconnector crash and disconnector spring crush protection. The curved bow has a backbone and the HIPERSHOE finger pad lets you tune lever length and finger position. Fits AR-15 and AR-10 pattern lowers.
