The CMMG dissent is a new pistol from CMMG that looks to make a substantial improvement over the AR design. Most notably a side charging upper, that needs no buffer handicap. This compact self defense gun is chambered in 300 black out but there are currently other models in 5.56 and 5.7. All of these are built around a 6.5″ barrel making them one of the smallest viable PDWs available today.

18:59 Final Thoughts on the Dissent

FIGHT JOE!
The main question I had remains unanswered. How much gas to the face.
Hex mags stink
The .300 Blk specific mags are generally needed for loading heavy, fat nosed lead bullets. The fat nose will impact on the side guide ribs on some 5.56 mags resulting in jams if you load more that 5-6 rounds. But for typical spitzer bullets regular 5.56 mags work fine.
Where is the one that take ak mags?!?! The dude from cmmg said it was dropping with this…
Cool blaster. Not happy with the 1:7 twist, would have preferred a 1:5.
The problem with 5.56 mags is when you load more than a few fat subs they bind up. I can’t even load most of my 5.56 mags full with normal subs.
Why wouldn’t CMMG go to a 1:5 twist rate for the .300 BLK Dissent?? A 1:5 twist rate would stabilize those heavy sub-sonic projectiles more reliably, and it would also give a slight increase to the amount of energy ft lbs delivered on target..
I swear I hear that song from Commando in that song somewhere…
I can't wait for CMMG to upsize this design to Short action cartridges and maybe chamber in the new 8.6 Blackout.
But yes, CMMG is missing the whole faster twist for .300 Blackout and they should embrace the muzzle taper.
Also what brand of stock?
can you tell us what suppressor you are using?
cmmg better than rattler
The 556 is too short, the 300 black out is on the bleeding edge, the 57 doesn’t take FN mags.
I’m not sure why we’re friends, you like fords, I like Chevys. But we all have our flaws.
I’d like this in 7.62×39
Not really into 5.7
And 556 this is just to short
Looks well machined, and the non-reciprocating side-charging handle when suppressed is always a plus! Thanks for a great review!
Is he not going to mention how he cut himself on the charging handle, there was blood all over the upper?
Shut your ravioli chute
Direct impingement you say? So it could be compatible with mil-spec barrels if CMMG wanted it to be. It would be nice to have the option to change this to a 8.5” inch barrel with a faster twist rate like 1/5 for both heavy subs and light supers.
Fucking A Curt!!! Lol People love to go back to Clint Smith's statement about "If it doesn't go the first time then get it outta there", sure! I'd normally agree, kinda Haha EXCEPT nowadays the ammo is 100% higher, if not more! Throwing a round on the ground when you don't have to is nice not to have to do. In my experience, most of the time the gun is just dirty or something small. It's not normally the bullet's fault Lol having that nice little cut out on the bolt is simple and EXTREMELY useful when it's needed. I like the idea of having a mountable assist instead of the shell deflector or just combine them. My ONLY complaint with these rifles/pistols is that fucking MSRP…… WHY CMMG????? Come on you guys' Haha I saw $1,800-$2,000, correct me if I'm wrong Curt??
To me there’s a few things any carbine or similar needs. One is some way to battery assist. Another is a last round bolt hold open (looking at you AK’s and MP5’s). The 5.7 version interested me except that IMO a 5.7 carbine/pistol should always use a P90 mag.
THE SRP FOR THAT IS $2K….RATTLER IS $2.5……WHICH IS A BETTER BUY?
WRONG HANDED…..LOL
Only issues I had with mags was with heavy subs ….
4140 cmv?? Ughhhh. And yes I shoot 3 million rounds a week and need all the power in can get.
2:56 the hammer and trigger pins both walking out bad…
Do I spy a set of Ultradyne C4 sights?
Looks like you need some captured Hammer and trigger pins. They were walking out already! Not good. I do like the platform may get an upper for my Banshee 22lr SBR as it does not require a buffer on it.
I have the same feelings about C products magazines as you do with P mags…
Looks like a Badass little blaster!
but if you add charging handle to bolt, it will be additional opening in upper past ejection port and that kinda sucks
…that's a nice looking weapon.
How do you like the iron sights?
I really appreciate the way you explained your methods and how you went about testing the gun. Thank you.
Very cool gun. I wonder why they didnt go with the 1:5 twist, but this seems to work fine with the 1:7. CMMG has been doing great stuff
220gr projectiles are the only ones that need/ should have 300blk mags. If you intend on only shooting suppressed get 300 specific mags.
Trigger pins we’re walking out
It's a 300blk mpx. I like it
It's a shame the barrel is only 1:7 twist. Needs to be 1:5. I have had issues running 220 grain subs in 556 mags.
If you have a malfunction, your not just going to push a forward assist anyway. Tap, rack and bang remember? Pull mag; rack, insert mag, rack and bang.
