  • No FA Uppers

    You just can't go wrong with these no forward assist uppers. If my cartridge doesn't slide into the chamber easily, then I sure don't want to force it! Stoner never had a forward assist on his design. It's unneeded. The price is right on these and they will accept a dust cover. Just what I needed.

  • One of my favorite uppers

    I'm glad Aero makes a slick side upper to pair with the M4E1 lower. Im all about reducing weight any way I can, plus I have no use for forward assist.

  • Great value!

    Great upper at a great price. The finish is a little less black and slightly grey. I tried this on a Spike's Tactical and then a Anderson lower and the color was a closer matched with the ST. Also, the fit was a little better on the ST as well. I got the version with the dust cover installed and I am glad I did. One less part to install and it fit perfect. Very happy with purchase!
