Complete buffer system kit combining the Gauntlet Arms adjustable carbine stock with heavy-duty Mil-Spec buffer components and an H3 carbine buffer. This kit delivers enhanced recoil management, durability, and reliable functionality—providing everything needed for a functional buffer system engineered for tactical shooting applications.
This kit eliminates the need to source individual buffer components separately. You get everything required for a functional buffer system—stock, tube, buffer, spring, and end plate—in one package. The 6-position buffer tube pairs with the adjustable Gauntlet Arms carbine stock to accommodate shooters of different sizes and preferences, while the H3 buffer provides enhanced cycling characteristics and recoil management for tactical shooting scenarios.
The Gauntlet Arms adjustable carbine stock is constructed from nylon reinforced polymer, delivering durability and strength without excessive weight. Six positions of adjustment allow you to dial in your preferred length of pull for different shooting positions or gear configurations. This stock is engineered to provide a sturdy, reliable platform that withstands frequent use and maintains consistent function through extended shooting sessions.
The included H3 carbine buffer offers increased weight for shooters seeking improved stability and enhanced recoil management. This heavier buffer weight contributes to smoother cycling characteristics and reduced felt recoil, which can be particularly beneficial in tactical shooting scenarios or for shooters who prefer more controlled recoil impulse. Paired with the standard carbine length recoil spring crafted from spring steel, this combination supports reliable cycling while managing recoil effectively.
The Mil-Spec heavy-duty aluminum buffer tube ensures compatibility with standard AR-15 lower receivers and reliable stock operation through extended use. The AR-15 M16 Mil-Spec phosphate-coated metal receiver end plate provides corrosion resistance and a solid connection for secure buffer tube installation, maintaining system integrity and allowing for staking if desired.
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—heavier buffers may require tuning for optimal function. This kit includes buffer system components only—lower receiver and other parts sold separately.
