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. Our Slick-Side is not intended as an exact match to our 6061 80% lower; they are compatible, though, and frequently purchased together. 

Weight 6.0oz



Please note - while many of our customers enjoy the look and simplicity of the "as machined" aluminum, this finish is intended to be completed by the end user; therefore, machining marks may be visible. Applying a wear resistant coating (Cerakote or similar) to as-machined uppers prior to use achieves final fitment and provides a barrier to resist rapid wear that will otherwise occur. 

Compliance with all federal and local laws is YOUR responsibility.

    Billet slick side

    Posted by Tom on Nov 18th 2020

    3 stars but NOT because they're bad. They are literally average, Middle of the road quality. I bought four. They're mostly in tolerance, the forward connection lug is under sized and the bevel is inconsistent between all 4. Keep this in mind, I am absolutely not complaining for this price. I acetone soaked em to prep for paint, that didn't take off the tooling grease. Luckily I have a blasting cabinet so if you plan to cerakote, white them first with 100 grit.

    For (sale price omitted) each, they're good value. If you're not set up to "do it yourself" these are the wrong product for you. I like the stuff from venom and I will continue buying from them.

    Beautiful machining! Fit between this and the billet lower are flawless. Can't wait to put some color on it and finish my build. Thanks!

    One nice chunk of aluminum

    Posted by Gregory Waugh on Sep 25th 2020

    I used some Mother's mag and aluminum polish on this thing and got a mirror finish. It fits my lower tight and works great.
