Aero Precision

The Aero Precision M4E1 Lower Receiver delivers billet aesthetics in a forged package. This custom designed enhanced forging is machined from 7075-T6 Aluminum and compatible with all mil-spec AR15 parts. Aside from the visual upgrades this custom engineered design provides that challenge much more expensive billet options, we have added several functional features to the lower receiver to simplify the assembly process for the at home builder.

M4E1 Lower Receiver Improvements:

• Threaded Bolt Catch Roll Pin - Allows for simple installation of the bolt catch and virtually eliminates the chance to damage the finish during installation (pin included). 1/16" Hex Key required for assembly.
• Integrated Trigger Guard - Eliminates the possibility of breaking the trigger guard tabs by integrating the trigger guard into the lower, creating a stronger more rigid platform to build upon.
• Upper Tension Screw - Allows users to fine tune the fit of the upper and lower receiver using a nylon tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver.
• Threaded Takedown Pin Detent Recess - Allows user to easily install the Takedown Pin detent and spring with the use of a 4-40 set screw (no more launching detents across the room).
• Increased Magwell Flare - Increased the flare of the magwell to aid in quick and efficient magazine changes.
• Marked and milled to accept short-throw safety selectors, but will work with standard selectors as well.

Includes:

• Stripped M4E1 Lower Receiver
• Nylon tipped tensioning set screw
• Threaded Bolt Catch Pin

Aero Precsion AR15 Stripped Lower Receiver is the perfect base for your custom AR15 build. Machined to mil-spec dimensions, their lowers work with standard AR15 components and ensure the highest quality with a correct component interface.

Includes:

• Stripped AR15 Gen 2 Lower Receiver in OD Cerakote H-232Q
• Nylon tipped tensioning screw
• Billet Trigger Guard - OD Green

The Aero Precision BREACH® is a rugged, ambidextrous, precision-manufactured charging handle for the AR15 platform. The BREACH's design utilizes a reinforced 7075-T6 aluminum bar that is up to the most demanding tasks. Its ambidextrous levers feature a patent-pending, dual spring system, that directs the force-of-use into the robust charging handle body. This allows the shooter to use a one-sided charging technique without compromising the part — a pitfall for traditional mil-spec charging handles.

The small lever configuration provides a low-profile, easily gripped interface that is comfortable when slung and can be actuated effortlessly from either side of your rifle.

• Ambidextrous Controls: Ergonomically designed 7075 Aluminum levers allow the user to easily charge their firearm with either hand, while remaining low profile and comfortable when slung.
• Robust Construction: Reduced chamfer angles on the 7075 Aluminum reinforced bar design provide a strong foundation for the BREACH® that is resistant to rotational flex or breakage.
• Patent-pending Lever Mechanism: Transfers force-of-use away from the roll pins and into the top/head portion of the reinforced bar protecting the charging handle in the most demanding circumstances.
• Gas Deflection Shelf: Aligns with the upper receiver to redirect gas flow away from the users face when shooting suppressed.
• Functional Design: It is not all just good looks. Stylistic cuts on the charging handle also help to clear stuck on carbon and debris from the upper receiver, while the spacer design seals and protects the lever mechanism from debris.
