CMMG DISSENT MK4 9mm 6.5" - AR-15 Pistol

When compactness is the priority, the CMMG DISSENT MK4 9mm 6.5" delivers 9mm AR-15 performance in a pistol-format configuration built for maneuverability without sacrificing reliability.

The CMMG DISSENT MK4 9mm 6.5" is a semi-automatic AR-15 pistol chambered in 9mm, built around direct impingement operation for reliable cycling on the AR-15 platform.

Lower Recoil, Better Follow-Ups: 9mm in a carbine platform delivers noticeably softer recoil than rifle cartridges, making faster, more accurate follow-up shots easier across extended strings of fire.

Ammunition Economy: 9mm ammunition is typically more affordable per round than centerfire rifle cartridges — an advantage that adds up quickly across training sessions and competition.

Unified Ammunition Logistics: Shooters who carry 9mm handguns can standardize their ammunition supply across pistol and carbine, simplifying what you buy, store, and carry to the range.

Home Defense Versatility: The carbine format offers more stability and better accuracy potential than a handgun alone, while 9mm keeps overpenetration risk lower than rifle cartridges in close-quarters use.
