Proper heat treatment ensured via proprietary flash-nitriding processĮach PRO cam pin is precision ground after heat treatment to exacting specifications and given a nitride finish.Swaging is the industry standard, however this process creates more stress on the bolt during manufacturing by displacing material rather than cutting it to the proper dimension from the start. The cam pin channel is counter bored, eliminating the need for swaging. When properly heat treated, 9310 steel provides superior strength and durability when compared to C158. Machined from 9310 steel, a proprietary flash nitride process was chosen to ensure proper heat treatment on the bolt. The bolt is one of the most important parts of the bolt carrier group. Each component and manufacturing process of the PRO 5.56 Bolt Carrier Group was deliberately chosen to increase the reliable service life of the bolt carrier group and its components. The Aero Precision PRO 5.56 Bolt Carrier Group is built from the ground up to meet the demands of the most extreme conditions. Enhanced Carbine Buffer Tube, 6-position.All standard carbine stock options made to work with mil-spec buffer tube dimensions are compatible with our Enhanced Carbine Buffer Tube. Mil-spec Dimensions - Machined from a 7075-T6 Aluminum Impact Extrusion to mil-spec dimensions.While some turn these threads down, we've correctly machined the threads to the proper depth, providing a much cleaner look. Proper Thread Depth - Traditional buffer tubes feature extended unused threads that can cause your stock to become trapped when fully collapsed.

Simply hold down the adjustment piece and push your stock onto the Enhanced Buffer Tube. We have removed the need for messing around with screwdrivers to get your furniture over the end of the buffer tube. Ramped Tube Design - Allows for effortless installation of traditional carbine stocks.During routine operation, smoother cycling is achieved by allowing additional air to escape during the compression cycle of the rifle. Position Guide Drain Holes - Each position guide features a drainage hole that removes water from the system in marine environments.The Carrier Support Extensions also extend on either side of the buffer retaining pin, securing the pin in place while simultaneously preventing the buffer tube from backing out under recoil. Carrier Support Extensions - Fully supports and guides the bolt carrier group into the buffer tube after a round is fired, preventing carrier tilt and unnecessary wear on key components.AR15/AR10 Enhanced Carbine Buffer Tube Features: This kit highlights our Enhanced Carbine Buffer Tube that delivers features that increase the reliability, security, and simplicity of your build. The AR15 Enhanced Carbine Buffer Kit is the perfect complement to standard AR15 rifle builds.
