Frequently Asked Questions

What makes the Colt CK901 unique?

The Colt CK901 is unique as it's an AR-platform rifle chambered in 7.62x39mm, specifically built for a Yemeni military contract. It utilizes standard AK magazines and features a more robust bolt carrier group than typical AR-15s.

Why does the Colt CK901 use a .308-sized bolt carrier group?

The larger .308-sized bolt carrier group provides enhanced durability for the 7.62x39mm cartridge. Standard AR-15 bolts can be prone to breakage when adapted for the larger case head of the 7.62x39mm round.

Can the Colt CK901 accept standard AK drum magazines?

The Colt CK901 does not feature a bolt hold-open mechanism. This is because the standard AK magazines it uses lack the necessary follower tab required to engage and activate an AR-style bolt catch.
