The Aero Precision AR15 Enhanced Carbine Buffer Kit with H2 buffer is built for shooters who need to fine-tune their rifle's cycling and reliability. Whether you're dealing with an over-gassed barrel, building a short-barreled rifle, or assembling an AR pistol, the H2 heavy buffer slows bolt carrier group movement under recoil to tighten up operation and reduce wear. This kit combines Aero's purpose-engineered Enhanced Carbine Buffer Tube with quality components designed to work together from day one—no guesswork, no missing parts.
The Enhanced Carbine Buffer Tube is the heart of this package. Its Carrier Support Extensions fully cradle and guide the bolt carrier group, preventing carrier tilt and damage to internal parts. Those same extensions lock the buffer retaining pin in place and stop the tube from walking backward under recoil—a real problem with standard tubes. The ramped tube design lets you slide any mil-spec carbine stock on without tools or wrestling; Aero also machined the threads to proper depth so your stock collapses fully and sits flush instead of jamming or looking half-finished. For wet environments or routine shooting, the position guide drain holes shed water and allow air to escape during compression, keeping the cycle smooth.
Built from 7075-T6 aluminum and machined to mil-spec tolerances, this kit is made in the USA and plays nice with all standard carbine stocks. You get the Enhanced Carbine Buffer Tube, H2 heavy buffer, carbine buffer spring, endplate, and lock nut—everything needed to drop into your lower receiver and run.

You get the Enhanced Carbine Buffer Tube, H2 heavy buffer, carbine buffer spring, endplate, and lock nut. Everything you need to assemble a complete buffer system for your AR15 lower.
The H2 is the right choice for over-gassed barrels, AR pistols, and short-barreled rifles where you need to slow down the bolt carrier group and reduce wear. If your rifle isn't over-gassed and you're building a standard carbine, Aero also offers this kit with a standard carbine buffer.
Yes. The Enhanced Carbine Buffer Tube is machined to mil-spec dimensions, so it's compatible with all standard mil-spec carbine stocks. The ramped design also makes installation tool-free—no screwdrivers or fitting hassle.
Yes. The Carrier Support Extensions extend on both sides of the buffer retaining pin, securing it in place and preventing the tube from creeping backward under recoil—a common issue with standard tubes.
