With virtually the entire SIG Sauer line made in its Newington, N.H., facility, SIG Sauer is proud to produce American-made firearms. A few of its notable firearms include the MCX multi-caliber rifle andMPX familyof submachine guns. With a large military and Law Enforcement customer base, SIG has been able to develop commercial variants of its military contracted firearms, including the MCX. The MCX is an AR-variant rifle that has the ability to change out barrels, handguards and stocks. Additionally, as a multi-caliber firearm, it can quickly be converted to fire .300 BLK, 5.56 NATO and 7.62x39 mm. SIG's MPX is another military firearm converted for the average consumer market. The idea for this gun was to bring back the MP5, but with a more modern design. The MPX is offered in an 8" pistol model without a brace, an 8" pistol version with a brace, 8" SBRs and a 16" with a telescopic stock. Check out this segmentfrom a recent episode ofAmerican Rifleman TV to learn more about SIG Sauer and its MCX rifle and MPX family of submachine guns.
