Phase 5 PBS Pistol Buffer Spring for AR-15

Enhanced Performance for Your AR Pistol

The Phase 5 PBS Pistol Buffer Spring is purpose-built for AR-15 pistol platforms, delivering the extra power and durability serious shooters demand. This isn't a compromise component—it's an upgrade that transforms how your pistol cycles.

Key Features

• Extra Power: Engineered to provide enhanced spring force for reliable cycling across various ammunition types
• Improved Cycle Operation: Delivers more consistent performance shot after shot, reducing malfunctions
• Superior Materials: Heat-treated and corrosion-resistant steel wire construction withstands extended use and harsh conditions
• Proven Design: Compatible with standard AR-15 pistol and carbine platforms chambered in .223/5.56mm

Why It Matters

Buffer springs are critical to reliable function. A worn or inadequate spring leads to short-stroking, failures to feed, and frustrating malfunctions. The Phase 5 PBS addresses this with a heavier spring rate that ensures your bolt carrier group cycles fully and returns to battery consistently. Whether you're running suppressed, shooting heavy ammunition, or simply demanding reliability, this spring delivers.
