The lower receiver bears the standard "SIG" logo on the left side of the magazine side with the address and serial number above the trigger and features ambidextrous magazine release and safety levers, shortened bolt catch paddle, and added quick-detach sockets machined into the buffer tube ring. Fitted with a SIG Sauer textured polymer pistol grip and Bushmaster M4 pattern telescoping buttstock. Mated to the lower receiver is an ARES Defense Systems SHRIKE 5.56 belt fed upper receiver group, designed to offer similar capabilities to the FN M249 SAW in a smaller package able to install on a standard AR-15 pattern lower receiver and able to feed from either M27 ammunition belt links through the top feed tray or standard AR-15 pattern magazines through the magazine well. It features a 16 1/2 inch M249 pattern profile barrel fitted with a SureFire "SFCT-556" closed tine flash hider and fixed front sight base with adjustable winged post front sight with fiber optic insert, folding left-side mounted charging handle, quick-detach barrel latch on top of the trunnion, ventilated aluminum handguard with Picatinny rail sections running along the top, sides, and bottom, and a hinging top cover with integrated Picatinny rail on top without a rear sight. Includes an aluminum ARES Defense M249 ammunition box adaptor block for the magazine well. Magazine absent.

Excellent, retaining 97% plus original anodized and phosphate finishes with a few minor handling marks and carbon residue on the flash hider. The furniture is also excellent. Mechanically excellent.
