CMMG Dissent Mk4 .300 BLK | 14.5″ Pinned/Welded | 2x30rd

The CMMG Dissent Mk4 is an AR-pattern rifle chambered in .300 BLK with a 14.5" barrel that is pinned and welded to a 16.1" overall configuration, supplied in a black finish and packaged with two 30-round magazines. It features the DISSENT side-folding stock with adjustable length of pull and an adjustable cheek riser, a forward non-reciprocating charging handle, and an M-LOK handguard with a top Picatinny rail. This setup provides a compact handling profile while retaining legal rifle length through the pinned-and-welded barrel. For a practical optic under $1000 that pairs well for close-to-medium engagements, consider a 1–6x variable such as the Vortex Strike Eagle 1-6×24 for fast target acquisition and flexibility.

The Dissent Mk4 balances compact handling with AR-platform ergonomics and the versatility of .300 BLK for hunting and precision target work at appropriate ranges. The pinned-and-welded barrel offers a shorter handling profile while maintaining rifle-length status, the side-folding stock reduces storage footprint and eases transport, and the M-LOK handguard provides straightforward accessory mounting. For shooters seeking a compact, adaptable AR-style rifle that accepts common .300 BLK loadings and arrives ready with two 30-round magazines, this configuration offers a practical, no-nonsense option.
