Minnesota-based Maxim Defense this week announced a new series of rifles complete with PROOF barrels and Gisselle triggers: the MD:11 

The new MD:11 is a Direct impingement AR-10 style rifle offered in 6.5 Creedmoor or .308 Winchester, with all models using 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.
 

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.

No MSRP is currently available.
