The APF Armory Extended-Face Buffer is a purpose-built component designed exclusively for the APF Armory Integrated Side-Folding AR-15 Lower Receivers. Standard buffers often cause compatibility issues with side-folding mechanisms — this proprietary extended-face buffer solves that problem by providing the correct geometry and engagement needed for smooth, reliable operation.
Machined to tight tolerances, this buffer ensures consistent bolt carrier group cycling while the lower is in both the folded and extended positions. At 4.4oz, it delivers the ideal weight for proper function with most standard AR-15 uppers and barrel lengths.
Key Features:
- Extended-Face Design – Specifically engineered for APF Side-Folding Lowers
- Perfect Compatibility – Optimized for use with APF Armory’s integrated side-folding mechanism
- Reliable Cycling – Ensures smooth operation in folded and extended configurations
- 4.4 oz Weight – Ideal balance for most AR-15 builds
