Due to production backlogs, lead time for this product in As Machined is currently 3 weeks from date of order; Black is approximately 4 weeks from order date. *Please be aware: all production lead times are estimates only; these are in no way guarantees of product shipment dates. 


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



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.

    Venom Defense magic! No milling marks, finish is uniform and very smooth, really unique looking and probably the best looking upper out there at a fraction of the cost of others, my bcg fits nice and snug with no wiggle yet slides perfectly smooth

    Upper came in flawless with no visible machining marks. The coating was smooth with no blemishes. Also has a neat cut out above the charging handle if you have a graphic on your charging handle.

    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!
