Yeah, yeah – you already have a lower. Why buy a new one? Because we can engrave it before we even ship it to your FFL!
All of our lower are priced to include engraving. That means no going to the post office, no wrenching on your existing lower to save on back-and-forth shipping, and most importantly—no extra waiting. Just buy, transfer, and go.
Best of all, we provide you with your serial number when your lower ships so that you can prepare your Form 1 for timely filing, and we even include fingerprint cards at no cost.
In stock and shipping now! This product is currently en route from the manufacturer, as it was more popular than the stock we had on hand. Please allow for a few extra days of processing before your order ships.

We are not shipping new firearms to California at this time, sorry.
The 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
