The Foxtrot Mike Products Gen 2 AR-15 Rifle comes with all the popular features that you expect in an FM Products rifle like the non-reciprocating charging handle and monolithic style upper receiver with an integrated recoil system. This unique recoil system utilizes dual recoil springs nested in the top of the upper receiver allowing the use of a folding stock. However, it still utilizes a traditional direct impingement gas system with a mid-length gas tube and a pinned and indexed gas block that prevents gas leakage and is extremely resistant to twisting or coming loose. The FM Products FM-15 is designed to improve the functionality of traditional AR-15 rifles without sacrificing on price.

  • 4 Position non-reciprocating side charging handle
  • Integrated side folding lower receiver with Magpul SL stock
  • Magpul MOE-K2 pistol grip
  • Billet upper and lower receivers
  • Ambidextrous safety selector
  • 13.9" Pinned and welded barrel
  • Dead Air KeyMo muzzle brake
  • Lightweight barrel profile with pinned .625" gas block
  • Mid-length gas system
  • Proprietary lightweight BCG

The non-reciprocating side charging handle features four positions of adjustment allowing you to set it either on the right or left side and have it angled either up or down. Like much of the rest of the rifle, it utilizes a proprietary bolt carrier group that indexes with the charging handle and features a lightweight design.

The lightweight profile barrel comes in at 13.9" long and features a Dead Air KeyMo compatible muzzle brake that has been pinned and welded bringing the entire length to 16". The barrel is made from match grade 41v50 steel with a .223 Wylde chamber and a 1:8 twist rate for maximum compatibility with a wide range of ammunition.

This Primary Arms Exclusive model also features a Magpul SL Stock, K2-MOE pistol grip, and comes in at a great price.
