• Bravo Company Manufacturing

  mid to premium

  The MCMR uses a steel barrel nut and a patented anti-rotation interface, which is why a light or laser mounted on it keeps its zero.

  3 models · Hartland, Wisconsin

• Geissele Automatics

  premium

  The MK16 won the USSOCOM URGI contract. Bought where an IR laser has to hold zero under load, which is a harder requirement than holding an optic.

  3 models · North Wales, Pennsylvania

• Aero Precision

  budget to mid

  The Atlas rails mount to Aero uppers without a separate barrel nut. The S-ONE is the slim one at a 1.5in outside diameter, which suits a C-clamp grip.

• Midwest Industries

  mid

  A 4140 steel barrel nut and seven sides of M-LOK at a mid-tier price, with a lifetime warranty.

  3 models · Waukesha, Wisconsin
