Dissent PDW

THE PERSONAL DEFENSE WEAPON, or “PDW” is a useful concept that is probably overlooked more than it should be in modern defense planning. PDWs are more subcompact packages, such as the M1 carbines of old, a H&K MP7, or the more notable FN P90.

The concept is for a more compact and easily carried firearm for self defense and security, rather than a full-sized carbine or battle rifle. However, it also includes a more powerful cartridge than a sub-machine gun pistol round.

Most firearm purchases are for either hunting, range fun, or defense. So, a PDW seems to fill the defense role more than a traditional semi-automatic rifle would.

Of course, pistols are more commonly used for defense because they are easily concealable. However, pistols are more difficult to master than a rifle, and are always underpowered. This is why a shorter PDW, is advantageous, especially with a stock.

CMMG recently jumped into filling the modern PDW role with their rollout of the Dissent line. Although it looks like a short AR15 on the surface, the lower receiver is where the comparison ends.

The upper receiver is a completely new design which eliminates the need for a buffer tube. The hybrid bolt is charged by the forward side charging handle much like an MP5 handle location (but no, we don’t get to “slap” it).

The Dissent is currently available in either 5.7x28mm, 5.56mm NATO or 300BLK, each with a 6.5-inch barrel. When I heard the barrels were that short, I chose the 5.7x28mm for testing because it was an obvious PDW caliber. 300BLK would have been my second choice.

For defensive use I try to stay at least 11 inches long on 5.56mm NATO, even though fireballs out the end of the barrel always make for a fun time.

Another reason I wanted to test the 5.7x28mm model is that it utilizes CMMG’s Radial Delayed Blowback (RDB) action. Unlike traditional gas impingement systems, the RDB system is a hybrid of a traditional blowback design with a modified AR15 bolt face that delays the bolt movement ever so slightly in order to cycle reliably and with less recoil. This design makes it perfect for a PDW setup.

The Dissent also comes with a picatinny rail on the rear of the receiver so you can choose to mount a stock. I chose to SBR mine in order to install the JMAC folding stock. Although it leaves a bit to be desired in precision shooting, it obviously helps for recoil control and target acquisition speed.

The Dissent ran great for me, and I even tested it side by side with an older model CMMG Banshee on a high-speed camera. I was surprised to see the Dissent model actually tamed recoil a bit.

The Dissent in 5.7x28mm wearing a Bowers USS suppressor makes for a nice defensive package. It’s perfect to grab in the house or even take camping, in your vehicle. Or stuff it in a bag for any defensive situations.

Accuracy wasn’t too shabby either. With Detroit Ammunition’s 40 grain load, the Dissent shot a 2.2-inch group at 100 yards, which for a 6.5-inch PDW is quite adequate.

CMMG has begun shipping out Dissents to dealers. Find out more at cmmg.com.
