The patent-pending Compact/Type Restricted (CTR) is a drop-in replacement for the standard M4 stock body.

Designed for stability, the CTR utilizes a shielded operation lever and a friction locking system that secures the stock to the buffer tube for zero movement.

Note: There are two types of buffer tubes (receiver extensions) in common use: Mil-Spec and Commercial.
