Product Description

The Timber Creek Outdoors AR-15 Buffer Tube Kit in Purple Anodized (ARBTKPPA) is a premium, color-matched lower receiver extension assembly designed to add custom flair and reliable cycling performance to standard AR-15 builds. Engineered as a complete drop-in buffer system, this kit includes a 6-position MIL-SPEC buffer tube, endplate, castle nut, standard carbine recoil spring, and 3.0 oz carbine buffer.

Precision CNC-machined from 6061-T6 aircraft-grade aluminum, the buffer tube features standard 1.148-inch outer dimensions to ensure tight, wobble-free fitment with all MIL-SPEC collapsible stocks. The top indexing ridge contains six precision-drilled position holes, allowing shooters to quickly tailor length-of-pull (LOP) for dynamic shooting positions, body armor, or thick outerwear.

Finished in a vibrant, corrosion-resistant Purple Anodized coating, the buffer tube, endplate, and castle nut deliver a bold custom aesthetic that withstands field wear, friction, and harsh solvents. Built to maintain smooth cycling mechanics and reliable lockup, the Timber Creek Buffer Tube Kit is an ideal upgrade for custom target, competition, or defensive carbine builds.

*Armorer Bench Notes & Real-World Staging Guidance:*

Fitment Matrix: Direct fitment for all standard MIL-SPEC AR-15 lower receivers. Accepts standard MIL-SPEC diameter (1.148") collapsible carbine stocks. (Includes 3.0 oz carbine buffer; verify buffer weight requirements for specialized suppressed or short-barrel setups).

1. Clean and degrease the lower receiver buffer tube threads and endplate alignment slot.
2. Slide the anodized endplate and castle nut onto the buffer tube before threading it into the rear of the lower receiver.
3. Depress the buffer retainer pin and spring into the lower receiver channel while threading the tube forward until the front lip captures the retaining pin.
4. Torque the castle nut to armorer specification (38–40 ft-lbs) using a non-marring castle nut wrench, then insert the carbine spring and 3.0 oz buffer into the tube.
