CMMG 55A520BAB Dissent BR4 | 5.56 NATO | 16.1″

The CMMG Dissent BR4 is a modern sporting carbine configured for jurisdictions that require restricted-capacity magazines. It ships with two Magpul 10-round PMAGs and a Magpul SGA stock fitted to a DISSENT billet receiver. For a practical optic under $1,000 that pairs well with this configuration, consider a Vortex Strike Eagle 1-6×24 for close-to-mid range accuracy and quick target acquisition.

This rifle is well suited to precision range practice and small-game or varmint hunting where a lightweight, familiar AR-platform carbine is preferred.
