Took the plunge and bought an m10x+ gen 3 from Calgary Shooting Centre. Figured I would do a little review for anyone interested.

Had them cerakote it OD green as well. Swapped the oem grip with a magpul K2 ( didn’t know at the time but these grips are almost the same profile). Cerakote looks very good, and the fit and finish of the rifle seems great. No sharp edges, and no play anywhere in the rifle. The Gen 3 have milled receivers as well.

Going to swap the brake out as well with a BCM compensator as well when I get some time. Have 2 pmags (20,10) and two m+m mags (one polymer one steel). The polymer m+m mag won’t insert empty unless you push the follower down first, but other than that all the mags fit good. I was on the original pre-order for these rifles when they were first coming to Canada, and backed out after all the crap that took place (IYKYK).

Now that CSC is the warranty centre and are looking after these rifles I figured I would happily give one a try. Got 1k rounds to burn so looking forward to seeing how it performs. Was going to have an update at the 500rd mark but unfortunately i couldn't make it to 20 rounds. The problem being that the receiver latch that captures the upper receiver will not stay closed. To hinge the rifle open you can either depress this button with the stock open using a small flat head screwdriver or bullet tip, or you can fold the stock and push it in while pushing down on the handguard to hinge the rifle open.

After about 2-3 rounds fired this latch works itself forward and the rifle just spreads open like a cheap hooker. Obviously there is some sort of heavy spring in that mechanism that is damaged.

*Full disclosure. I originally had trouble getting the rifle apart. I read the owners manual and followed the steps listed but couldn't get the upper to budge. I assumed that maybe the tolerances were extra tight because of the Cerakote i had applied to the rifle. Eventually the rifle opened. It turns out it was something wrong with the receiver latch and had to be sent back to CSC to be repaired.

The rifle came with 1 magazine, a steel 5/30 AK M+M magazine. I also bought a polymer M+M 5/30 , a 5/20 PMAG from CSC and a 5/10 PMAG(from RDSC).

Metal mag worked great, no issues.

Polymer M+M magazine: Could not insert into the rifle empty as the follower went to high and flared the magazine out. Inserted OK once rounds were in it. However, this magazine was pinned too tight and is actually an extra-safe 4 round magazine. Magazine was returned to CSC with the rifle and received a replacement (metal) magazine that works great.

20 rd Pmag: Flawless. Rounds go in easy, feeds/cycles great

10 rd Pmag: Pinned too tight. Can barely squeeze 5 rounds in. Will seat in the rifle with 5 rounds however the BCG will not clear the 1st round when trying to be manipulated back. Removing 1 round fixes this and it works. Another extra-safe 4 round magazine. I have reached out to RDSC regarding the 10 round PMAG, and shipped it back (at my own expense) and they replaced it.

The rifle was received back at CSC on a Wednesday morning, and I had it back in my hands repaired and working great on Friday. Very happy with the fast turnaround time.

I have now shot 180 rounds of Norinco red box and 25 rounds of Hornady 123gr HP. 2 M+M metal 5/30 mags worked flawless, as well as my 5/20 PMAG. The PMAG is my preference as i shot from the bench. Of the all the rounds I fired the only malfunction I had was once using the 5/10 round PMAG as mentioned above. Other than that the other 204 rounds all fired flawless. They all fed and extracted nicely. Extracted cases all landed in the same area @ 4-5 O'clock.

CSC recommended running the rifle in gas setting 2(higher gas flow) so there's no malfunctions. The manual says to run in setting 1 to put less stress on the components which is why I asked their gunsmith what they recommended. For ####s and giggles I ran the first 40 rounds on setting 2 then the remaining on setting 1 and I had zero malfunctions on either.

Accuracy was better than I figured it would be with the red box Norinco. I was using my Burris MTAC 1-4x24, and the majority of rounds were in a 3-5" group and this was from a pretty hot barrel. I sighted the rifle in also with my Vortex 3.5-10x50 and shot the match grade stuff using this scope. I was surprised when there was virtually no discernable difference between this $2/round ammo and the norinco red box. I shot from the bench, 100 yards, front and rear rest and never from a hot barrel. I know this cartridge has its limitations but I expected quality ammo to run somewhat better. Oh well i guess! Will try some other stuff if I can find some thats priced reasonable.

Take down is a breeze, and the charging handle is ambi, and switches sides in about 10 seconds. Remove the charging handle, open the rifle and the BCG slides out. The piston assembly is easy to remove and clean as well.

All in all, the rifle is a blast to shoot. I've been missing range time with my (banned) semi's and this rifle has been fun to shoot. I know 205 rounds doesn't mean $hit but just wanted to provide a small review for those interested! I will update again once I have something new to report.gun1.jpeggun2.jpegtarget 1.jpeg
Left target was the hornday match, right was norinco red box. As you can tell hardly any change in accuracy.

Red box norinco.

I've got some Norma ball ammo that my T81 hates but shoots near MOA in my CZ600.
The T81 does well with Polish surplus, and prints around 3-4moa for 10 rounds with a red dot.
Worth sourcing out some differing ammo or try hand loading for your M10x

Yeah that’s the plan. Got 150 rounds of the match stuff so I’ll use that brass to load some up. Will try a few different kinds when I can. Gets expensive though buying 3 different boxes from 3 different dealers and paying shipping for all. Hard to find somewhere that has a bunch of different kinds.
 
I've got a gen3 m10x and I've got to say I'm VERY impressed with it.

I have almost 500rnds of mixed Barnual and NC Norinco copper washed ammo thru it and not 1 single issue of any kind.

This version I think M+M finally got it right. I personally was skeptical (after having the Gen 1 and gen 2 short handgiard rifles absolutely blow) I wasn't holding my breath on this one but it definitely has proved me wrong.

It might actually be a keeper in the safe next to all the other x39 rifles I have.

Any more accuracy reviews? I loved my second gen one, but goddamn did it pattern like buckshot (and not that nice flight control stuff).
That just killed the rifle for me. Love the look and feel of it, I'd buy another in a heartbeat if they came out with some halfway accurate rifles.
 
...and at considerable savings to a gen 3.
Which begs the question: If CSC can get the earlier gen rifles running like tops, what do the gen 3 rifles offer over the earlier models?
Milled Receiver with resultant much tighter fit between the Receiver and the extruded aluminum Receiver Cover/Handguard. Off the top of my head, that and some tweaking of the internals was the magic "runright sauce".

I just posted a quick review of my new Gen 3 Carbine earlier tonight as I had not seen this thread. Hopefully the Mods can combine our 2 complimentary threads...
 
On the gen 3, do the fasteners on the upper (referencing the one below the ejection port, and one above the safety on the right side) hold the upper receiver 'proper' with the 'railed handguard' (for lack of terminology)?

Those 2 screws that appear to secure the Upper Receiver to the Body Cover/Handguard are only found on the new Gen 3+ model, not the standard Gen 3M version. My carbine is the 3M version, which retains the Gen 2 full-length extruded aluminum Body Cover/Handguard with no scews. Those screws appear to prevent the Steel Upper Receiver from sliding within the extruded aluminum Body Cover/Handguard only on the Gen 3+. That same function is perfomed on the Gen 2 by the Main Hinge Pin and a Grub Screw, plus a series of 3 small cutouts on the top edge of the steel Lower Receiver which mate with steel projections on the Upper Receiver when the two halves are shut together. This system of cut-outs and projections prevents the steel Upper Receiver from sliding along the Lower Receiver, which in turn prevents the Steel Upper from sliding within the aluminum Body Cover/Handguard.

Note the 3x cutouts along the top edge of the steel Lower Receiver and the projections on the Steel Upper Receiver that mate together when the two halves are closed up:

I am currently just past 270 rounds through my Gen 3M 12" Carbine, with 1x failure to eject thus far. Other than that simple stoppage (which was quickly remedied), reliability has been 100%.

Appreciate the update and please do keep us posted, it's a rifle I've always wanted to like and it sounds like this version delivers!

Love the irons you are running! What are they? Still working well for you?
 
so $2.5k for something that is no better than an SKS?
Well, that all depends on your definition of "better". If you mean shorter and handier, then yes, the 12" M10X Carbine certainly fits that bill. If you mean that the M10X has a far superior Trigger, then yes, correct. The M10X is also faster and easier to reload with Magazines and features all ambidextrous Controls. Depending on your viewpoint, the M10X may also be more esthetically pleasing, although there is no accounting for taste....

I guess that’s subjective. If you like old milsurps then I suppose you should stick with an sks. I am enjoying the modern features and ergonomics tho. I always really disliked the ergos of my sks. That’s why I always seem to get rid of them.

The accuracy so far (for me) unfortunately has been about on par with an SKS though.
