MK17 CBC-E Patented.

compact battle carbine – enhanced

6.5 Creedmoor, 7.62×51 NATO, 308 Win

The Compact Battle Carbine-Enhanced (CBC-E) is a derivative of the SWORD Defense Systems MK17 platform. The CBC-E was designed at the request of our end-user communities as a multi-purpose solution that provides significant increases in both stopping power and effective range. The CBC-E was designed for close-quarters engagements, urban operations, and low-profile mission sets where the end-user might quickly transition from close proximity contact to taking a shot beyond the effective range of typical duty rifles. The weight and overall length have all been optimized to give the end-user enhanced ballistics and accuracy in a lightweight and agile carbine. The CBC-E is equipped with a specially designed 13″ barrel and an enhanced stock that reduces the overall length of this platform by 6” when compared to its full-size counterpart. These modifications have created a compact, lightweight, and powerful carbine with phenomenal knock down power that exceeds 300blk and 7.62×39 at close range, while allowing the end-user the ability to reliably engage beyond 700 meters with high hit probability. The CBC-E utilizes SWORD’s free-floating forend system with MLOK compatible slots at the 3, 6, and 9 o’clock positions, along with a full length picatinny rail at the 12 position. The CBC-E is readily adaptable to meet the demand for flexibility and modularity in lethal applications for special response situations and military requirements.

The CBC-E is offered in .308 Win, 7.62 NATO, and 6.5 Creedmoor.
