The MR762A1 is a semi-automatic, short-stroke gas piston rifle chambered in .308 Win/7.62×51. This example features a heavy-profile 16.5 inch barrel with 5/8x24 threads and the SureFire SFMB-762 muzzle brake installed, offering a durable, suppressor-ready interface and flat shooting characteristics.
The rifle uses a free-float slim aluminum handguard with elongated slots and a continuous T-marked top Picatinny rail for secure, repeatable mounting. Controls include an ambidextrous safety selector with pictograms and standard receiver features for reliable operation. The receivers, handguard, and barrel have a matte black finish.
Furniture is practical and robust: an HK-marked collapsible buttstock with a thick recoil pad and rear sling loop, paired with a Magpul FDE pistol grip. Length of pull measures 12.75 inches, and capacity is 10+1 with the included magazine.
Optics are ready to go out of the box.

This setup complements the rifle's accuracy-focused barrel and free-float rail.
