MCX-SPEAR

PART OF SIG’S SUBMISSION FOR ARMY FUTURE WEAPONS

Sig’s MCX Spear series carbine aims to be the Army’s NGSW-Rifle, replacing the M4. Standard features include a fully collapsible and folding stock, rear and side charging handle, free-floating reinforced M-LOK handguard, fully ambidextrous controls, and a quick-detach Sig Next Generation suppressor.  

Sig’s Lightweight MG is a belt-fed general-purpose weapon intended to become the Army’s NGSW-Automatic Rifle, replacing the M249 while hitting the scales at 40 percent lighter and with a round that has double the effective range of 5.56. 

Both platforms use Sig’s 6.8mm hybrid ammunition, which is billed as offering a significant reduction in weight over traditional ammo while offering better performance and greater penetration while using a 121-grain bullet.
