KE Arms is now offering longer trigger/hammer pins for use in CAV-15 MKII lower receivers. These popular polymer AR-15 receivers can use regular trigger/hammer pins but they have a wider exterior dimension than a standard receiver. The longer pins sit flush with exterior of the receiver.
From KE Arms:
Long hammer pin for the CAV-15 MKII polymer receiver.
The hammer pin area of the CAV-15 MKII is wider than traditional receivers. While normal hammer pins work with them, many users have requested longer pins that sit flush with the outer edges of the receiver. These pins give the user quick visual identification that their pin is in place and centered.
Made in the USA of steel and melonite coated.
Compatibled with Cavalry Arms CAV-15 MKII, GWACS Armory CAV-15 MKII, Sabre Defense SR-15, and Eagle Arms M-15P.
