MD:15L RIFLE
For civilian shooters who demand reliable performance in a lightweight AR-15 platform, the Maxim Defense MD:15L delivers duty-grade features without compromise. Chambered in 5.56 NATO, this rifle offers superior balance and control with a spiral fluted, free-floating barrel that reduces weight and improves heat dissipation. Outfitted with Magpul MBUS® iron sights, the MD:15L is range-ready out of the box, while the 7-sided Slimline handguard provides full M-Slot compatibility for mounting optics, lights, or grips.
At the heart of the MD:15L is the Zero™ 3lb match trigger from Blackout Defense, designed for ultra-fast resets and exceptional accuracy. An ambidextrous charging handle ensures intuitive handling for both left- and right-handed shooters. Whether you're upgrading your home defense setup or investing in a versatile range rifle, the MD:15L combines Maxim’s engineering excellence with the features modern civilian shooters want most.

Have about 1000 rounds through it so far. Super smooth and lightweight compared to other rifles in its class. 0 Malfunctions with standard 855 green tip ammo. Will warn that the trigger is light on the pull and single stage so it will surprise you and some new shooters I let try this rifle have accidently bumped off an extra round. Has the durability feel of a Daniel Defense for much less of the price.
