6.8x51mm SATO Modular AR Grenadier Configuration (40mm Grenade Launcher attached) Fully Ambidextrous, compatible with AC magazines. Developed based on the previous M31's mechanisms, except it's now chambered in a more powerful cartridge with several other improvements to stability and reliability.
For Umbra use ONLY. @I_am_Good_Scratcher for upgraded RPPS Based on the Remington ACR I just realized this looks awfully close to some of the RFARs. ARMA I refuse to jump on the NGSW hype train!!!!!!
