AR-15 Slick-Side Billet Upper Receiver

(3 reviews) Write a Review

Due to production backlogs, lead time for this product is currently 2-3 weeks from date of order. 


Simple. Clean. Affordable. 

Our Slick-Side upper omits the traditional forward assist, shell deflector and dust cover for a clean and simple addition to any AR-15 build. Our Slick-Side upper is precisely machined from premium, billet 6061 aluminum to ensure the tightest tolerances, in many cases, exceeding mil-spec requirements. Compatible with both forged and billet lower receivers as well as most types of fore-ends and quad rails. 

Weight 6.0oz


*Note regarding the thread:

No cause for concern. The flattened pieces are actually just a production element.  If you look closely at our stock photos (that are cerakoted), you can see the flattened sides.  The thread is slightly wider than the flats on the sides, so when we machine the flats, a small amount of the thread gets milled away in the process. We have performed testing to verify that there are no adverse effects of machining them this way. Then, the entire thread is covered by the barrel nut after assembly, obscuring those areas from view.

    Great Upper!

    Overall this is a great upper for the money. It looks really cool. I paired it with an M4E1 and it looks good despite not being a perfect match.

    There is a small machining defect near the charging handle catch but it is very minor. The fit with the M4E1 was pretty loose before adjustment.

    These uppers are amazing! With great detail and are flush on sides when mating with mil-spec lowers! Will buy more!

    Purchased as machined so i could polish it myself, surface was very smooth and had no visible imperfections. Very good customer support as well, would highly recommend.
