The Sugar Weasel is a 7-inch direct impingement rifle chambered in 5.56. It's built on clear anodized M16 spec receiver set with a cerakote finish (no forward assist) and features the same fast-twist barrel Cherry Bomb muzzle brake adjustable gas block and 6-inch M-LOK handguard. It uses a 6-position receiver extension (AKA "buffer tube") that houses a carbine length action spring and buffer.
