PWS A5 Enhanced Buffer Tube
The PWS A5 Enhanced Buffer Tube is an A5‑length mil‑spec receiver extension designed for use with VLTOR‑pattern A5 buffers and rifle‑length springs. It is built specifically for enhanced reliability, smoother cycling, and increased system stability—particularly beneficial on suppressed rifles, SBRs, and high‑stress usage.
Key engineered features:
- Impact‑extruded 7075‑T6 aluminum construction for maximum strength
- MIL‑A‑8625F Type III Class 2 hard‑coat anodized finish
- Extended carrier support lip for smoother cycling & reduced carrier tilt
- Fluted anti‑tilt tube design that clears debris and lowers weight
- Lightening cuts reduce weight by ~1 oz vs standard receiver extensions
- Enlarged drain holes for water and debris clearance
- Unique extended A5 receiver extension offering more stock positions (GunMag lists 8 positions)
This tube is A5‑length, meaning it requires A5 buffers and rifle‑length springs (NOT compatible with carbine buffers/springs).
