Anyone every had both of these that compare them?
I already have a KAC SR15 16" and QDC can but looking to grab a SBR. The LMT 12" CQBPS seems like a very nice set-up.
Have it narrowed down to these two.
I’m a lefty and this will be shot 100% suppressed.
Neither of these options will be pleasant for a lefty to shoot suppressed. Get one of the new sionics ergp 11.5 barrels or a hodge 12.5. Both of those will be much more pleasant to shoot suppressed than the options your have mentioned.

OP, I’m left handed, I’ve spent some limited time behind a KAC CQB MOD1 and NT4 and I found it fine to shoot. Ya there’s some blow back, ya my face got dirty, no it was not miserable. I probably wouldn’t do it while wearing a tux.
Lol Sionics and Hodge… you’re comparing two meme grade companies that popped up in the last couple years to one with 30+ years of pedigree that holds multiple contracts with major government agencies and produces rifles and accessories that are killing people on multiple continents. These rifles aren’t even in the same league.

The limited blowback isn’t a concern.
You get use to it as a lefty
I’ve been interested in both of these also, as a complete factory SBR. I don’t have hands on experience. Having the QDC can already, would tip that towards the KAC upper. I’ve never been very interested in piston ARs but on paper the 12” LMT sounds pretty awesome. For me, I’m leaning towards the LMT. I love the MARS lower, and it would play well with my surefire cans. Everything I’ve read/heard about the LMT has been positive. I’ve been running a 10.5” LMT DI upper on a Colt 6933 for 11 years. It’s been great! And runs perfect. But the blowback with an m4-2000 and SDN-6 is harsh!
What would make either of these two better than a KAC or LMT with regard to “pleasantness”?
Smaller gas ports with the ops context of 100% suppressed. My knights cqb mod 2 with qdc can has the worst gas to my face of the carbine gas system 11.5 or 12.5in uppers that I own. As the op is a left handed shooter, my understanding is the gas is felt even more than a right handed shooter like me. I used to have an older lmt that I sold because it was so unpleasant to shoot suppressed. Dont get me wrong, I love my cqb mod 2, but I would not recommend it as a 100% suppressed platform.

Port size is going to do just about nothing with regard to smoke at the ejection port.
That’s pretty much 98% a function of the suppressor and bore diameter.
Smoke and gas at the shooter with a suppressor is significant even with a bolt action, blow-back or piston gun.
KAC uses a pretty small port, FWIW, but that’s to keep the gun from running too fast when suppressed.
I’m surprise to hear that as mod 2 has pretty tight seal gas port compares to others brand, therefore the gas blow back shouldn’t be that bad…

KAC 11.5" has been purchased
Figured all my KAC gear has been fantastic so no reason to change.
I currently have an lmt mrp 10.5 upper and the current version of the KAC CQB SBR. The KAC is on one of my factory lmt lower while waiting for the lower to clear ATF.
In the past I had an lmt mrp 12.5 piston. I did not care for it for a number of reasons. It’s heavy! There’s a lot of moving parts and when shooting it it feels like all of them are moving in different directions at once. In other words, it is not smooth at all.
By contrast, the KAC CQB upper is much, much smother and lighter. It’s an all around better product and it’s not just my dislike of the piston. I still have one 10.5 mrp and it just sits in the safe. Don’t remember the last time it went out.
Moreover, you can get the KAC CQB uppers. It’s a simple solution. A local dealer has a couple complete KAC CQB SBR (ie, complete rifle). I buy the rifle and sell you the upper for $1675. He lets me take the upper upon payment. I just want the lower!
good call
i have both a cqb mod 2 and a 12" mrp and both are great guns but in that you can only keep one scenario i would take my cqb over the mrp
I run my 11.5" Mod 2 CQB with a dedicated 5.56 QDC.
I consider myself a man of discerning tastes—if someone brings me the wrong wine or beer I will notice.
However, I don’t know how good my nose/eyes are but I can’t really tell a difference between it and my 16" Mod 2 when it comes to “gas in the face” suppressed.
Could you let me know what buffer and spring combo you running for your 11.5/QDC set up? May be ammo too. Thanks

100% stock setup on both. The 16" Mod 2 comes with a carbine weight buffer and the 11.5" with an H2 equivalent.
