Maxim Getting in the Long Game

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. I found it to be a laser on the range (Photo: Chris Eger/

Maxim says the MD:11 was initially designed for USSOCOM 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.
