he TRIARC Systems A5 Buffer System Kit is built for AR‑15 platforms, using the VLTOR A5 design for enhanced recoil control, wider operating range, and consistent reliability.
Included components:
- A 7‑position A5 buffer tube machined from 7075‑T6 aluminum
- TRIARC Enhanced A5 buffer spring, chrome silicon
- High‑carbon steel castle nut
- Steel end plate with sling socket
Finishes are available in Type III Black Anodize or Type III Hard Coat Anodize, with Dry Film Lubricant applied to inside and outside surfaces. The DFL coating forms a thin solid film that reduces friction, prevents galling and fretting, resists corrosion, and operates across a broad temperature range—enhancing durability without attracting dust or grit NASA Technical Reports Server+12Arrow Finishing+12Sandstrom Coating Technologies+12Sandstrom Coating Technologies.
