Bushmaster 6.8mm SPC Semi Automatic Carbine 6.8mm Remington SPC 16" M4 Barrel 26 Rounds Black M4 Collapsible Buttstock Black Anodized Finish.
This gas operated semi-automatic packs a bigger punch than 5.56mm/.223models - a .270 caliber 6.8mm SPC (Special Purpose Cartridge) specifically developed for the military, but now available commercially. Velocity averages a bit over 2600 FPS (with Hornady 115 Gr.V-Max), and the heavier bullet weights deliver excellent terminal energies. The 6.8 SPC was developed from a .30 Remington case which is shortened slightly to fit the AR15 type magazine. Due to the "fatter" case diameter, magazine capacity in a 30 round AR-15 type shell is reduced to 26 rounds, and 6.8 SPC specific springs and followers are used. The bolt is also different - due again to case diameter (take care not to interchange a 5.56mm/.223 bolt with a 6.8mm SPC bolt). Includes a lockable hard case with operator's safety manual, 26 round steel magazine, orange safety block and black web sling. One year Bushmaster warranty.
