The MK1 Mod2-M Upper is built with a PWS Triad muzzle device, known for reducing recoil and muzzle rise. The 1:8" twist rate in the barrel is optimal for stabilizing a wide range of bullet weights in both .223 Rem and 5.56 NATO calibers.
This upper is optic ready, meaning it does not come with factory-installed sights, allowing shooters to install their preferred optical systems. The 11" PWS PicLok handguards provide a comfortable and secure grip while offering flexibility for accessory attachments.
