Angstadt Arms
Overview
The Angstadt Arms AR-15 9mm Buffer Kit is designed specifically for carbine-length builds, featuring a Mil-Spec buffer tube that ensures compatibility with a wide range of AR-15 components. This kit includes a buffer only, optimized for 9mm applications, which helps to manage recoil and ensures reliable cycling during operation. You'll typically find this buffer kit in builds focused on 9mm performance, providing a solid foundation for an effective pistol caliber carbine setup.
Builders on GunPartPicker first added the Angstadt Arms AR-15 9mm Buffer KIT to a build in April 2026.
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today 6 of the 7 retailers we track have it in stock. The best price crept up from $46.39 to $54 over August 2026. Buying today, the lowest price is $52 at Classic Firearms, above August's low of $46.39, so a better deal may come back.
