Another AR-15 variant, chambered in .458 SOCOM, appears as the “FTac Recon”. It is classified as a battle rifle, even though the real .458 SOCOM cartridge isn’t a full-powered one.
The rifle appears to be built on an otherwise generic milspec M16 lower, a la the default “M4” in-game, but with aesthetic similarities to the “XRK M4” from Modern Warfare (based on a Radian Weapons receiver) on the left side around the magazine well. The left side of the upper receiver bears a vague resemblance to a Mega Arms GTR-3H with grooves similar to the JP Enterprises CTR-02, but with said grooves cut in the opposite direction; the right side appears to be based on a Wilson Combat Stripped Billet AR-15 upper or a CMMG MkW-15 upper.
Unlike the 5.56 “M4″ seen above, the upper receiver lacks a forward assist, which is reflected in the inspect animation when the operator does a brass check. By default it features what looks like a 12” barrel with an A2 flash hider, a KeyMod handguard based on the BCM KMR, an A2 pistol grip and a Magpul PRS stock. It also feeds from regular black stylized .458 SOCOM PMAG 10 round magazines.
