Close Quarters Carbine
MK1 MOD1 CQC
The RD MK1 MOD1 CQC is a 12.5-inch short-barreled rifle chambered in 5.56 NATO, engineered for close-quarters engagements where reliability, precision, and performance are non-negotiable.
This system is equipped with the RD KFM Taper Lock Flash Hider for optimal suppressor integration, a Battle Arms Development RACK® ambidextrous charging handle for enhanced operational versatility, and a Nickel Teflon-coated single-stage trigger for consistent, responsive fire control.
A patented threaded gas tube system virtually eliminates gas leakage while reducing felt recoil—resulting in improved control and accuracy under sustained fire. The thermal-fit 11.7” M-LOK® handguard with our tombstone lockup provides superior rigidity and heat resistance, ensuring long-term durability in high-stress environments.
Purpose-built for modern warfighters and tactical professionals, the MK1 MOD1 CQC reflects RD’s commitment to delivering small arms solutions without compromise.
