The Icon Defense Lowers are made from MIL-SPEC 7075-T6 forgings, our machining leaves no die seams or flash marks on the receivers. We all also hold our lugs to a .001” tolerance for the best fitment in the industry. Our experience and background in the aerospace industry along with twenty years in the firearms industry helps to ensure our parts are dimensionally accurate and of the highest quality.

The attention to detail on this receiver set is awesome. The upper/lower fitment is amazing, parts stay together without the take down/pivot pins installed. The machine work is very nice, and the finish is top notch.

We got to play with the Icon Defense hand guard at Shot Show and was impressed. The design is simple, classic, and clean. At Shot Show, I was concerned the fitment was too tight, but when we got our first order in, we were so happy with how the Upper and Lower fit together. The tolerance is literally perfect with zero play, but not so tight you can’t break the weapon down for maintenance. I didn’t notice until we received our first order how nice the finish is. The coatings ICON uses are so nice. Our first custom build is nearly complete and can’t wait to run it with the Lower, Hand Guard, and especially that BCG!

ICON is top-shelf! The anodizing is flawless. The upper and lower fit is perfect: not excessively tight but snug with no play. Get a set.

Probably the best forged lower on the market. The anodizing is absolutely beautiful, and it has incredibly tight fitment with their uppers. But what really sets these apart is the company behind it. Icon Defense/Killer Innovation stands by their products, and their customer service rep and even their foreman were amazingly responsive and polite when I contacted them about a small blemish on the first one I received.
