Sig Sauer has expanded the MCX series of rifles to include the commercial version of the U.S. Army’s XM7 rifle in the MCX-SPEAR rifle. The Army rifle is a part of the Next Generation Squad Weapons (NGSW) program. The civilian version has been eagerly anticipated since the NGSW program was announced. The MCX-Spear currently is available in 7.62 NATO and 6.5 Creedmoor, with 277 SIG Fury coming later.
“The SIG SAUER-MCX family of rifles has become synonymous with innovative engineering and premium quality in a reliable and proven carbine.” said Tom Taylor, Chief Marketing Officer and Executive Vice President, Commercial Sales. “The next generation has arrived with the new MCX-SPEAR, offering enhanced AR-10 capabilities in the MCX platform for the first time on the commercial market.”
According to Sig, the MCX-SPEAR is an adapter multi-caliber rifle packed full of features the end-user would expect and want. The SCX-SPEAR features a rear and side non-reciprocating charging handle for the ultimate flexibility in shooting positions and optics options with the gas-piston system. The system also features a two-position adjustable gas valve for shooting suppressed or non-suppressed. The rifle is suppressor ready with the Sig SLH and SLX suppressor-ready QD mount flash hider.
The MCX-SPEAR has fully ambidextrous controls with bolt catch, bolt release, and other fire controls. The rifle has a lightened free-floating M-LOK handguard with a full-length Picatinny rail for the attachment of accessories. Additionally, the system has integrated stainless steel QD mounts in the lower receiver for a fast and easy way to attach a sling.
Rounding out the features of the Sig MCX-SPEAR rifle is a 6-position folding Magpul SL-M stock, a two-stage Matchlite Duo trigger, and ships with one 20-round magazine. The MCX-SPEAR also has a user-interchangeable barrel to swap between calibers easily.
According to the Sig Sauer company website, the rifle will be available in full-length, short-barreled, and pistol lengths. Barrel lengths will range from 16” for the full-length down to 13” for the SBR and Pistol versions. All weapons have a coyote tan anodized finish.
