Armaspec AR9 Firing Pin – AR-15 9mm Conversion

The Armaspec AR9 Firing Pin is designed specifically for AR-15 platforms chambered in 9mm. This firing pin addresses the dimensional differences between standard AR-15 rifle firing pins and the requirements of pistol-caliber blowback systems, ensuring reliable primer strikes on 9mm ammunition. Essential for builders converting AR-15 lowers to 9mm or assembling dedicated 9mm carbines, this firing pin works with compatible 9mm bolt carrier groups.

Machined from stainless steel with a corrosion-resistant finish, the AR9 firing pin installs like a standard AR-15 firing pin and requires basic armorer-level disassembly of the bolt carrier group. No permanent modifications or professional gunsmithing needed. Compatible with most AR-15-pattern 9mm bolt carrier groups that accept AR9-style firing pins.
