FN America Mid Range Gas Gun (MRGG)

Do you love the FN SCAR? Interested in what is essentially a variant, or at least a close relative of the SCAR? Then you’re going to love the FN America Mid Range Gas Gun (MRGG) line. The MRGG lineup from the respected gun maker is currently made up of two rifles, the MRGG-A and the MRGG-S.

The launch of the FN MRGG-A and MRGG-S was initially reported by Soldier Systems, who wrote:

Offered in two variants MRGG-A for Assault and MRGG-S for Sniper Support. The most glaring differences between the two variants are a 14.5″ barrel for MRGG-A and 20″ MRGG-S as well as different pistol grips and buttstock for the two versions. However, the side-folding adapter fits with an M4 standard buttstock so the shooter can configure the stock as he sees fit.

Controls are ambidextrous. Additionally, only MRGG-A offers full-auto fire. Otherwise, it’s semi and safe selectors for both, but it is more ergonomic than on the SCAR. There’s also a two-stage trigger which was designed in house.

Features of the guns include:

  • AR-style top-mounted charging handle
  • Non-reciprocating side charging handles
  • A combination forward assist and brass deflector
  • FN’s own two-stage trigger
  • Height adjustable bipod
  • Barrel lengths specific to their purpose (14.5 inch on MRGG-A and 20 inch on MRGG-S)
  • Compatible with SR25 magazines
  • Full-length MIL-STD 1913 Picatinny Rail
  • M-LOK compatible as well
  • Adjustable gas block
  • Suppressed and unsuppressed settings on gas block
  • HUXWRX Safety Co. suppressor
  • Cold hammer-forged barrel
  • Highly customizable stocks and interchangeable barrels
  • Available in 6.5 Creedmoor and 7.62x51mm NATO
  • MRGG-A ships with a Gen 3 Vortex Razor 1-10×24 optic and a Badger C1 mount and Leupold Delta Point Pro backup sight
  • MRGG-S ships with a Gen 2 Vortex Razor 4-27×50 optic and a Spuhr 4002 mount with FN ELITY

Interestingly, Soldier Systems also noted that there’s an “adjustable gas block with suppressed and unsuppressed settings while the Gas Regulator is now buried in the receiver assembly and redesigned to reduce flash while shooting under NODS.” This is a fantastic feature for FN to include in the MRGG’s design. From their high-quality overall design to the thought that obviously went into the controls, it’s clear FN created these rifles to be the ultimate combat-oriented Mid Range Gas Guns.
