Angstadt Arms 8oz Buffer Kit for 9mm and 45 ACP AR-15s
This complete buffer assembly kit provides everything needed to optimize your 9mm or 45 ACP AR-15 platform firearm. The kit includes:
- 8oz solid-state buffer — engineered for reliable cycling in blowback AR-9 and pistol-caliber carbines
- Carbine buffer spring — matched to work harmoniously with the heavier buffer weight
- Buffer spacer — ensures proper fit and function
- Anodized black finish — durable and corrosion-resistant
Compatibility
Designed for use with both Glock and Colt-style magazine-fed AR-15 platforms. The 8oz weight provides the mass needed for reliable operation in 9mm, 40 S&W, and 45 ACP configurations.
Why This Matters
Proper buffer selection is critical in blowback pistol-caliber ARs. An undersized or oversized buffer can lead to unreliable feeding, premature wear, or excessive recoil. This kit delivers the balanced performance your firearm needs for smooth, consistent operation.
