What’s Included
- 1 × Magpul PMAG 30-round 5.56 polymer magazine
The Lancer carbon-fiber handguard trims weight while adding M-LOK slots for direct-mount accessories. Carbon fiber also dissipates heat rapidly, keeping the forend comfortable during extended strings of fire.
A SureFire muzzle brake is timed to the 16.25-inch, cold-hammer-forged barrel (1/2x28 threads, 1:7 RH twist). This brake noticeably flattens recoil, allowing faster sight recovery without compromising muzzle stability.
The Geissele Super SCAR trigger replaces the factory unit with a crisp, two-stage pull that shortens lock time and improves shot-to-shot consistency. Coupled with the SCAR’s oversized ambidextrous paddle magazine release and reversible extended charging handle, the controls feel intuitive for both right- and left-handed users.
A Parker Mountain Machine magazine well funnel/extension guides magazines into the STANAG mag interface for quicker reloads. The rifle also carries a Hogue finger-groove rubber pistol grip that enhances purchase in wet or gloved conditions.
The SCAR’s side-folding, telescoping polymer stock offers adjustable length of pull and an adjustable cheekpiece, making it easy to tailor the fit for body armor, optics height, or different shooting positions.
