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.

    Billet slick side upper

    Posted by Unknown on Jan 27th 2020

    First be aware that this upper comes raw, as in sharp edges and visible tool marks., you will need it tumbled or media blasted. The design is unique, the mechining is excellent w/ the exception of the above caveat and a tiny ridge in the carrier way. Not a big deal. Also you need to be aware there's a hole milled through the pic rail all the way into the receiver, it's at the rear and shouldn't cause an issue, I just wasn't expecting, nor aware of it. I rate it 4 stars simply because I haven't completed the build yet. There may be a follow up afterwards.

    While this upper is quality made, the description was vague. It did mention that it should be coated for ware but no mention of figment to a raw lower receiver .
    I will recommend this upper already coated but was looking to use it in the raw to match my 80’s...
    Thanks for the understanding Sam.

    Slick side upper

    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

    Great upper, will clean machining

    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!

    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.
