What’s Included
- Century Arms C93 Sporter 5.56mm semi-automatic rifle
- One 30-round translucent brown polymer MEC HK33-pattern magazine
The C93 Sporter uses the same roller-delayed blowback action found in HK33 and HK93 rifles, delivering smooth recoil impulse and reliable cycling with 5.56mm NATO or .223 Remington ammunition.
A 16.25-inch, 1:9-twist U.S.-made barrel is parkerized for corrosion resistance and threaded 1/2-28 TPI. The threads allow easy attachment of muzzle devices or suppressors, and a triple-lug sight tower with hooded front post maintains the authentic HK profile.
The rifle’s steel receiver is finished in grey parkerizing and fitted with a welded scope mount for quick optics installation. A paddle-style magazine release and left-side charging handle replicate the original HK ergonomics, while a manual safety provides familiar controls.
Black polymer furniture includes a fixed stock with raised cheek piece and butt-pad for steady cheek weld, plus a slim-line handguard that keeps the front end light. The 4-position rotary diopter rear sight offers precise, repeatable adjustments for various engagement distances.
