Complete buffer system kit engineered for AR-15 platform builds, combining a SOPMOD style collapsible stock with integrated storage compartments and heavy-duty Mil-Spec buffer components. This USA-made kit delivers adjustability, practical utility, and reliable cycling performance—providing everything needed for a functional buffer system in one package.
This kit eliminates the need to source individual buffer components separately. You get everything required for a functional buffer system—stock, tube, buffer, spring, end plate, and castle nut—in one package. The 6-position buffer tube pairs with the adjustable SOPMOD style stock to accommodate shooters of different sizes and preferences, while the standard buffer and spring provide reliable cycling characteristics for typical AR-15 configurations.
The SOPMOD style collapsible stock offers more than just adjustability—built-in storage compartments provide convenient space for batteries, spare parts, or cleaning accessories. Six positions of adjustment allow you to dial in your preferred length of pull for different shooting positions or gear configurations. Nylon-reinforced polymer construction delivers durability without excessive weight.
The heavy-duty aluminum buffer tube is built to Mil-Spec standards, ensuring compatibility with most AR-15 lower receivers and reliable stock operation through extended use. The included standard recoil buffer and carbine spring are constructed from high-quality materials designed to deliver consistent cycling performance in typical AR-15 carbine configurations.
US Tactical receiver end plate and castle nut complete the installation hardware needed to secure your buffer tube. These components ensure proper buffer tube positioning and can be staked for added security, maintaining system integrity through extended use.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Verify buffer weight and spring rate compatibility with your specific barrel length, gas system, and caliber combination. This kit includes buffer system components only—lower receiver and other parts sold separately.
