These units have cosmetic blemishes which will not affect function. 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, Aero has 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

M4E1 Blem Stripped Lower
I’ve done 4 builds with Gen2 lowers and WAS building my 5th. That was until I was able to pick up an M4E1 at a very good price. The features of this lower is amazing and I couldn’t find the “blem” anywhere. I’m very much looking forward to matching this with my RA535 trigger and the 13.7” BA Modern Series barreled upper. Great service and fast shipping too
Excellent Product
Hard to believe that this is designated as a "blemished" item. Package arrived in a timely manner and is exactly as advertised at a really great price.
Perfect!
I'm picky... But the person looking these lowers over to determine if they have blemishes or not is even more so! I can't find one on it ANYWHERE. Even so, if it did have a blemish it's still well worth the price.
Great Value
Could not hardly see any blemishes. Runs as expected.

Best Lowers, Bar None
The Aero Precision M4E1 lower is the best lower on the market as far as I'm concerned, and this blem looks just like a perfect lower to me. Excellent price too!

Nice lower reciever!
Excellent quality. Can’t find a blemished spot on it. Ar15discounts.com is an excellent website with excellent customer service.

I could only find one smudge on this lower. A bit of spit on a finger rubbed it out. I love these lowers!
