AR-15 RIFLE BUFFER 859819007164

AR-15 Rifle Buffer — Mil-Spec Weight & Length for Fixed-Stock Systems | UPC 859819007164 Build your rifle-length AR right from the core. The AR-15 Rifle Buffer (UPC 859819007164) delivers dependable cycling, smooth recoil impulse, and long service life in fixed-stock and rifle-length receiver extension setups. Precision made to mil-spec dimensions, this buffer pairs with a rifle buffer spring and rifle receiver extension (A1/A2 or rifle-length tube) to keep your bolt carrier moving reliably with 5.56/.223 and other AR-15 cartridges tuned for rifle gas. Why This AR-15 Rifle Buffer Mil-spec geometry & mass: Correct internal weight stack and overall length support consistent bolt velocity, reliable feeding, and positive lock-back on quality mags. Smooth recoil impulse: The buffer’s weight distribution and durable bumper help reduce felt recoil and muzzle dip, improving shot-to-shot recovery. Durable construction: Hardened components and a robust polymer bumper resist peening under high round counts and training cycles. Drop-in compatibility: Fits AR-15 rifle-length receiver extensions (fixed stocks) with a rifle buffer spring—ideal for A1/A2 stocks and precision rifle builds. Versatile performance: Proven with standard 5.56/.223 as well as popular AR-15 chamberings tuned for rifle gas systems (e.g., .224 Valkyrie, .350 Legend, etc.). Note: This is a rifle-length buffer. It is not for carbine receiver extensions. Use the correct tube and rifle buffer spring. Ideal For Fixed-stock rifles (A1/A2) and precision AR-15 builds Rifle-length gas systems seeking maximum reliability and soft recoil Bench, varmint, and match rifles where consistency equals accuracy Duty/training rifles that need dependable lock-back and repeatable timing Key Features at a Glance Platform: AR-15 (rifle-length buffer system) Use: For rifle receiver extension (A1/A2/rifle-length tube) Function: Controls bolt carrier movement; aids feed, extract, eject, lock-back Construction: Mil-spec materials with polymer bumper and internal weight stack Finish: Wear- and corrosion-resistant exterior UPC: 859819007164 Compatibility & Setup Works with: Rifle receiver extension (fixed stock) Rifle-length buffer spring (not carbine) Standard AR-15 BCG (5.56 carrier), matched to your caliber/chamber Do not mix: Carbine springs/buffers with rifle-length tubes (and vice versa). Gas system: Optimized for rifle gas on 18–20"+ barrels; can work in tuned intermediate setups where rifle-length timing is specified. Installation Tips (Quick Reference) Verify clear & safe. Separate upper and lower. Install spring & buffer: Insert the rifle buffer spring into the rifle extension, then follow with the rifle buffer (bumper facing outward). Retainer check: Ensure the buffer retainer captures the buffer correctly while allowing smooth movement. Function test: Cycle the action. Confirm smooth travel, positive lock-back on an empty mag, and proper bolt release. Pro Tip: Pair this buffer with a quality rifle spring and a properly sized gas port (or adjustable gas block) to fine-tune recoil and ejection for your load and suppressor use. Troubleshooting & Tuning No lock-back: Verify magazine and gas, then spring condition; confirm you’re using a rifle-length buffer and spring in a rifle tube. Violent ejection or bolt speed: Consider gas adjustment or heavier buffer options (where appropriate) while maintaining the rifle-length standard. Short-stroking: Check gas block alignment, gas port size, ammo, and spring fatigue. Maintenance Wipe carbon and debris from the buffer face and polymer bumper during routine cleanings. Keep a light film of oil in the receiver extension—avoid heavy grease that traps grit. Inspect the buffer roll pin and bumper for wear; replace components at signs of damage.
