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.

    Amazing Pieces

    Beautiful pieces and incredibly fast shipping too! These are some of the absolute Nicest uppers that I have and I have some skeletonized billet and some other slick sided uppers and these ones are still my favorites! The quality for value scale on everything I have gotten from Venom Defense has been 2nd to none and dractically exceeded my Hope's or expectations! Amazing Company, Very Highly Recommended

    Superb Upper

    Posted by Matt on Apr 13th 2021

    Found out about Venom-Defense through a local machine shop owner who was impressed with their work. I ordered two 6061 uppers and lowers. Lead time was 4+ weeks. Arrived in 5 days. I’ve owned about ten ARs from various manufacturers including Seekins, POF-USA, Palmetto, WMD Guns and a couple 80% 7075 billet lowers from another company. Also have had custom rifles built and I’m sure I land somewhere on the spectrum between OCD and @$$hole. I expect a product to be built right, with pride in workmanship and delivered exactly as described. This receiver set has some of the best machining that I have seen in the firearms industry. The fitment between the upper and lower is that of a matched set. Every edge is subtly radiused to eliminate any laceration hazard. There were absolutely no metal shavings left over from machining. No chatter in the metal and not a single portion of either receiver that was unfinished or only semi-finished. It’s obvious that Venom-Defense takes pride in the products they produce. Their attention to detail is second to none. I’m proud to have a great AMERICAN MANUFACTURER like Venom-Defense in my backyard and I look forward to picking up a couple 7075 receivers when they become available.

    This is a nice looking upper! Great quality. Venom makes great products My only regret is not buying from them sooner! I’ve only reached out to them once for something that wasn’t a mistake on their part and got fast, great customer service! While prices have increased, Venom has not taken advantage of the customer! All around great product, great company!
