How is the mutant for reliability? Was hoping someone would buy one and do a review after they put a considerable number of rounds down range

Like Brian46 says, how is that Mutant? I'd like to hear a good review on it also. Looks very promising.
The bolt face looks like it adheres to proper and approved Soviet design, where quality is measured by weight and mass.:)
I can't see the Mutant bolt face failing,....ever:

Unfortunately I have not been able to shoot it yet! Every time I've had time off, I've been rained out. Once I go, I'll give you an update. In the interim, check out these videos here:

The fit and finish of the rifle seen great so far. The only issue I've had was a slightly out of spec mag release screw. I have a new one coming my way after a simple email to CMMG. All issues I've seen on the net were dealt with my CMMG quickly and professionally. Their customer service seems to be top notch.

Only other issue I've had was a mag lock that was caused by myself. That is inherent to the AK platform and no fault of the gun. I was able to bang the mag out and my PMAG still seats well.
 
so i finally managed to get out to the range today. i fired 80 rounds through my MK47. Here are my initial thoughts. take them as you will:

Right off the bat, I will say that the gun had 1 malfunction with CanAm Dominion Steel Cased HP rounds. The round failed to chamber causing the bolt to only close halfway. The nose of the round was jammed up into the top of the chamber. Simple fix of removing the mag and cycling the action. This only happened once and it was on the second mag of the rifle. Never happened after that. Could be any number of things, but truthfully, I'm not particularly concerned at this point in time. I can't remember the exact name of this type of malfunction, but I hope I described it well enough.

That being said, the AK PMAGs while nice, posed an issue. While they hold 5 rounds, they hold them very tightly. I noticed that when I loaded up a mag to 5 rounds, I would have to really hammer it home for it to seat correctly and catch the mag release/catch. I also found that cycling the bolt was harder with 5 rounds in the mag. I think there is too much spring pressure pushing against the bolt when a 5-round mag is inserted. I'm not saying that it can't be done, but I had better luck loading in 4 rounds into each mag. I think if the PMAGs were pinned to 5.5 rounds it would alleviate the problem.

Other things I noticed was shell ejections. They would be launched 2m back and to the right in a consistent 1m grouping. Nothing wrong with this, just something I noticed.

In terms of performance, other than the initial issue, I had no problems whatsoever. Gun is heavy and I think would benefit from a UBR stock to help balance it out. I personally have a Magpul Fixed MOE stock on order. I didn't want to break the bank on the rifle as I wanted to build a KISS style rifle to pay homage to the AK series while still keeping that tacticool look inherent of the AR platform.

I only shot it out to 50 yards today I didn't have any spotter with me, so shooting it out to 100 would have been pointless as I would not have been able to see my hits on target. My shooting skills aren't the best. I need more practice, hence why I bought this gun (cheap ammo). With a better trigger I can honestly say that this is 1.5-2 MOA gun. I was able to squeeze off some 1MOA groups at 50 yards.

On my rifle, I did have a PWS FSC30 break installed. It certainly made the gun shoot well. Recoil was like a strong push. Best way I can describe it would be like going from a 9mm to a .45. The .45 lacks the snap, but has the push. That's how this gun felt to me vs shooting a 5.56 AR. Overall I found it very pleasant and fun.

Other than that, everything else that I noted were inherent to the rifle, such as having to rack the bolt every time a new mag was inserted as there was no bolt hold open. I knew this going in and while it is different and takes getting used to vs an AR, it was/is not a deal breaker for me. I would have zero issue with this had Canada have full capacity magazines.

I will update this once I shoot it more. I hope to do a 2-day rifle course in the near future, and plan on using this for one of the days. I will post again if and when I do.
 
Here is my latest 7.62 build:

Sig lower with Geissele Trigger and mad release, UBR stock

DD upper with Lothar Walther 16 barrel and Surefire brake, Troy duracoated HG

Using it with XCR 10 rounders. Very accurate with practically any ammo, but loves Russian surplus. No feeding issues. Tactical Ambush bolt is holding up very well so far.

So since the CMMG MK47 doesn't share any parts other than a trigger group with an AR why couldn't it be non restricted if someone could source or build an 18.5+ inch barrel? There are plenty of non restricted rifles out there that use an AR trigger group.

$2250 for the rifle, $400-$500 for a custom barrel, $60 for a verifier to do the paperwork, total $2710-$2810 depending on barrel cost + tax and shipping and you would have a pretty sweet 7.62x39 not far off the price of a new XCR-L. Cheaper once they are a little more popular and start showing up on the EE used.
Donster is there any way you could find out if it uses an AR barrel extension? If so making a barrel would be easy.

This rifle actually interests me as it was designed around the 7.62x39 cartridge and takes proper AK mags so reliability should be high and as long as it was cleaned well after running corrosive it should last a long time.

The review I watched on it looked like they were very impressed with it.

Donster, Blame your retailer or the importer of the magazines, they are the ones that pay someone to pin them and they should always be pinning to 5.5 and not 5.0.

I don't really blame anyone other than our silly mag restriction, but rules are rules even if I don't agree with them.

That being said, the gun should absolutely be NR. It can not be mated to either an AR10 or AR15 receiver, nor can either one of the aforementioned BCG be put into the rifle or vice versa. Oh well :(

Do they even sell the mk47 here?

They do. You can get them throug Questar.
 
I did notice something worth watching for with my 7.62x39 AR this evening that I have not run into with a .223.

I've fired aprx. 700 rounds of mixed surplus and new NC ammo through it. All of it is much dirtier than .223. The extra carbon built up in the firing pin channel in the bolt to the point that it was slowing down the firing pin enough to cause light primer strikes.

So, just like an SKS or VZ, make sure your firing pin will freely rattle back and forth when the bolt is assembled. If it doesn't, clean the firing pin channel in your bolt.

was the mk47 classified as restricted because its an AR15 variant or because of its barrel length?

Mechanical function still counts. Direct impingement, buffer tube with buffer and spring, etc etc. It is a ar15 system through and through even if it doesn't work with standard ar parts.

Same reason modern style ar10s are restricted and the original design, although unobtainium, is not.

Show how the mutant operates any differently than any other ar internally and you might have a case.

The only mechanical function that is the same is that it is a semi automatic rotating bolt rifle.
Sounds exactly like a Modern Hunter, not compatible with AR-10 upper or lower but still runs direct impingement system with AR-10 bolt and buffer tube system.
This rifle with an 18.5+ inch barrel should be able to be made non restricted just like I did with my Bushmaster ACR.
There are no parts other than the trigger group in this rifle that are compatible with the AR-15. The upper and lower are completely different and the bolt carrier group will not fit in an AR-15 or AR-10.

Amen to that brother. Stupid thing is that this doesn't even really look like an AR. I bet if it had been made with a side charger instead of the typical AR-15 charge handle style they would see it differently.
 
Small bump. CMMG just released their SBR option for the MK47. I'm sure Questar could bring these in:

MK47K

The Mk47 K is the shorter 10″ barreled version of the Mk47 full-sized variants. The Mk47 K features CMMG’s mid-sized receiver based on our Mk3 platform, carved from billet 7075-T6 aluminum. It also features an improved 9″ hand guard designed to be compatible with aftermarket muzzle devices and suppressors. The Mk47 was designed to harness the power and reliability of the 7.62x39mm cartridge utilizing a robust bolt based off our Mk3 (.308). The unique Mk47 lower receiver readily accepts all standard AK Magazines. Every rifle comes equipped with a MOE pistol grip, CTR stock, SV muzzle brake, Mil-Spec Trigger, 30rd AK PMAG, and CMMG’s lifetime quality guarantee.
