An Ambidextrous Charging Handle Designed for Your AR One of the most critical components on your AR-15 is the charging handle, since it gives you complete control over your gun’s firing status. Because of that, you need a charging handle that’s easy to use and durable, and Aero Precision has the perfect option in the form of its Breach Ambidextrous Charging Handle. Each Aero Precision Breach Charging Handle can be had in two different sizes, so you can choose the one that best meets your needs. The smaller of the two levers provides a sleek design that blends in with the overall lines of your rifle without creating any snag points, but it still provides a comfortable, ergonomic surface for easy racking. The larger of the two levers gives you more surface area for instant, easy activation of the lever, whether through rapid one-handed racking or other motions. The Aero

The M5 .308 Enhanced Carbine Buffer Kit is the perfect complement to standard .308 rifle builds. This kit highlights our Enhanced Carbine Buffer Tube that delivers features that increase the reliability, security, and simplicity of your build. AR15/AR10 ENHANCED CARBINE BUFFER TUBE FEATURES: 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. 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. Position Guide Drain Holes – Each position guide features a drainage hole that removes water from the system in marine environments. During routine operation, smoother cycling is achieved by allowing additional air to escape during the compression cycle of the rifle. Ramped Tube Design – Allows for effortless installation

Our state of the art M4E1 platform starts here, with the M4E1 Upper Receiver. The M4E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Through superior engineering, we have condensed the parts needed to mount a free-floated handguard to a mere 8 screws. Since the handguard mounting surface and upper are of the same forging, not only is it a stronger system, but we are able to make additional lightening cuts to save weight and allow for more efficient cooling. Ease of installation – Simply insert your barrel assembly into the M4E1 upper, tighten it using the provided barrel nut and wrench, slide your rail on and tighten the rail screws. Within minutes you have a modular, free-floated rail.
