Maxim Defense arrived at SHOT Show last week in Nevada with its new SR-25 style rifle, the MD:11, complete with options for a PROOF Research carbon-fiber barrel.

The new MD:11 is a direct impingement AR-10 style rifle offered in 6.5 Creedmoor or .308 Winchester, with all models using either an 18-inch PROOF Research carbon-fiber or stainless-steel barrel set in billet 7075-T6 receivers with a floating 15.5-inch M-LOK slotted handguard. The lightweight barrel helps keep weight down to the 9-pound range. Other standard features are a carbine buffer system, B5 SOPMOD stock, ambi surface controls, and Gisselle SSA-E trigger.

The MD:11 will be offered in urban, arid, and black schemes, and was clocking in on the long ranges at SHOT Show earlier this month. (Photo: Chris Eger/

Maxim says the MD:11 was initially designed for U.S. SOCOM requirements. However, once the decision was made to commercialize the SOCOM requirement (within limits), 6.5 Creedmoor and .308 Winchester were deemed the best calibers. (Photo: Maxim Defense)
