AR-15 Carbine Buffer — Reliable Recoil Management for Carbine-Length Systems (UPC 859819007171)
Give your carbine the smooth, consistent cycling it deserves with the AR-15 Carbine Buffer (UPC 859819007171). Engineered for carbine-length receiver extensions, this drop-in buffer helps tame recoil, protect internal components, and maintain a predictable bolt velocity for dependable function across a wide range of 5.56/.223 builds and comparable AR platforms.
Whether you’re refreshing a well-used rifle, finishing a new lower, or standardizing parts for an armory, this carbine buffer provides the balanced mass you need for everyday shooting, training, and range work.
Why Choose This AR-15 Carbine Buffer?
Dependable cycling: Optimized reciprocating mass supports reliable feed, extraction, and lock-back on empty with common carbine-length gas systems.
Reduced felt recoil: Smoother impulse for quicker sight recovery and more comfortable range sessions.
Parts protection: Proper buffering helps mitigate bolt carrier and receiver extension wear over time.
Drop-in fit: Installs in minutes in any mil-spec carbine-length buffer tube with a standard carbine spring.
Build versatility: Ideal for general-purpose 16" carbines, patrol rifles, and training guns.
Key Features
Carbine-Length Format: Designed specifically for carbine receiver extensions (not rifle-length A2 systems).
Balanced Standard Weight: Delivers the classic, widely compatible carbine recoil signature (commonly around ~3.0 oz; actual weight may vary by manufacturer).
Durable Construction: Robust body and internal weights built to handle high round counts and varied ammo.
User-Serviceable Platform: Works with standard AR-15 carbine action spring for easy maintenance and replacement.
UPC: 859819007171 (useful for inventory, checkout, and replacements).
Ideal Use Cases
New builds that need a proven, general-purpose buffer.
Maintenance refresh for rifles showing sluggish cycling or extra wear.
Training carbines where predictable recoil and reliability matter.
Armory standardization to keep parts common and service simple.
Compatibility
Platforms: AR-15 pattern lowers with carbine-length receiver extensions.
Stocks: Mil-spec carbine stocks that mount to carbine tubes.
Springs: Standard carbine action springs (not rifle-length).
Calibers: Optimized for typical 5.56/.223 carbine builds; works with many similar pressure cartridges. For suppressed setups, unusual gas systems, or alternative calibers, buffer weight tuning may be beneficial.
Note: This product is a buffer only. Pair with a carbine spring and carbine-length buffer tube (receiver extension) for a complete assembly.
Installation Overview (Best Practices)
Unload & clear the firearm—verify chamber and magazine are empty.
Remove stock (if required) and depress the buffer retainer to remove the old buffer and spring.
Insert spring & buffer into the carbine tube, ensuring the buffer is captured by the retainer.
Function check: Hand-cycle to confirm smooth movement and bolt catch engagement before live fire.
If you’re running a suppressor, very short barrels, or hot ammo, consider testing alternate buffer weights (H/H2/H3) to fine-tune ejection and dwell.

FAQs
Q: Will this work in a rifle-length A2 buffer tube?
A: No. This is a carbine-length buffer. Use only with carbine receiver extensions and a carbine spring.
Q: Is this good for a suppressed carbine?
A: It can work, but suppressed setups often benefit from a heavier buffer (H/H2/H3) to optimize ejection and reduce gas blowback.
Q: Do I need any special tools?
A: No special tools are required to swap buffers. Always ensure the firearm is unloaded and follow standard AR maintenance procedures.
Q: What if my rifle won’t lock back?
A: Check gas system health, magazine function, spring condition, and consider buffer weight tuning. A worn spring or under-gassed barrel can mimic buffer issues.
