Just figured I would share this because it is hard to find mags for these 7.62 AR-

Found some ASC 7.62 mags at whatacountry.com- bought 4 for now

I think everyone's out of the CPDs right now, I was going to order more 20s but every vendor I've used in the past is out of stock right now.
Which is normal, I think ASC & CPD makes their 7.62x39 in batches, when they come available seems like suddenly everyone has them.
I've got ASCs & CPDs, the ASCs have mostly worked for me but I'm liking the CPDs more and more, and they have stronger springs.
One of my ASC 20s started letting rounds nosedive when I loaded over 15 rounds so I swapped the spring with one from a 6.5 Grendel 25 rounder, so far it's worked fine but the Grendel spring is shorter front to back than the stock spring, which can force the follower to slip out of place if you press down too close to the front, like when you're forcing the follower to the bottom with a screwdriver. It's an improvement over stock but over time I've replaced the springs in every ASC mag I own except for the 10s and so far have had to do nothing to the CPD 30s or 20s.

Honestly because ASC and CPD are the two highest rated and ASC are the only ones I can find right now- have 6 ASC mags now, dry lubed the spring and follower, and am going to dremmel out the front lip so theres less of a chance for the case to catch on. Going this weekend to try them out, see how they function, just finished my AR yesterday.

I just ordered two more 10 round CPD mags from LCJ Wholesale. They carry 20 and 30 rounders too. I ordered 10 rounders because in the socialist people's republik of New Jersistan I am only allowed 15 rounds and since I haven't seen a 15 round 7.62x39 mag I'm stuck with the 10 rounders.

Northriver LLC- is where I just got my second order for CPD 7.62x39 AR 10rds mag, 28 rds mags and 30 rds mags- shipping was cheap.  As of now- 1/28/2016  10:00pm, the 28rds mags are still "in-stock".  Even when it says Back-ordered, you should still go ahead and put your order in, I did and still received all my mags 3 days later....

I just received two 30rd CPD mags from Northriver LLC myself. Honestly I can't tell much difference between them & the 30rd ASC mag I got from Primary Arms. Both CPD mags fit differently in my lower, one snug, the other would fall free. The ASC mag I got fit real tight, but a couple of passes with a file on the upper sides fixed that. All three mags would bind when I used a ruler to depress the followers. I'll take them apart & see if the followers need smoothing. For the time, I think I'm done buying anymore mags until my rifle shows me it has a clear preference. The reports on these mags are all over the place. Some people love them, others regret having to waste their time to throw them out.

Has anyone actually compared ASC and CPD at the range?
Link Posted: 1/29/2016 3:46:27 PM EDT
[#10]
yup I have
had 3 asc that worked then after a while needed the lip of the front of the mag filed down now they work some one about a jam every 10 rounds
have 3 c products gen 3 mags and all work and feed great no problems

c products only for me from now on

will be getting the psa ks-47 lower from palmetto state armory when they are available for sale
basically just like a cmmg mutant BUT it takes standard upper recievers where as the mutant has to have a upsized ar-10 upper and bolt and the ks-47 takes ak mags like the mutant but any ar-15 upper chambered in 7.62x39 or 5.45x39 will work for it

I, too, am interested in the KS-47 lower, but PSA hasn't clarified if it would require a modified bolt carrier (such as MGI does). The main issue with using AK mags with an AR upper carrier is the AK mag feed lips will not clear the carrier unless channeled out (which MGI does to theirs). How on Earth PSA got past that (IF they did) boggles my mind. I have a feeling they are NOT telling you that you also require a modified bolt carrier to use that KS-47 lower. They haven't mummed a word about it yet though.

Just went to the range yesterday, tested out my build I completed last week.  I used two ASC 30 rounders, one I had dry lubed and one I tore out of the package at the range.  The lubed mag seemed to work almost flawlessly, I did have a couple weak primer strikes which seemed to be Tulammo most the time. The non lubed mag had some feed issues, so I learned all my ASC mags need to be lubed.  Judging by everyones remarks about the CPD, I might try and sell my 4 unopened ASC mags and buy some CPD mags, we'll see!  More or less just happy my new AR operated so well!

my experience with 3 different ASC mags is all except one needed the front filed down.  I have 3 cpd mags that were and continue to be 100 percent from the start with no mods at all.  If you can find them the cpd's, from my experience and others on here as well, are much better mags.

Just checked gunbot end it appears that the lowest price per round is almost exactly the same for 7.62 x 39 and .223 Steelcase (21/22 cents)



I have been debating this idea, but the "shoot the cheap Ammo" argument seems to not hold true.  Now, is it really worth another caliber, new mags, etc?  Someone convince me (or not).  I have been on the fence for a while.  I found a KAK Industries barrel for $110 (made from Green Mtn blanks) and I have all the other parts (unless I need a new BCG and mags)



Help me arfcom, you are my only hope for my first world problems

The case taper on the .223 doesn't lend itself well to steel case.  Both x39s do.  I have yet to see a steel case .223 SP or HP do much good in a ballistics gel block.   Many steel case SP and HP have done bad things to ballistics gel blocks.



Simple, get on youtube, find the cheapest ammo with a "good to you" looking ballistics gel test for .223, and the same for the 7.62x39, and see where the price differs.



If you just want to blast, the point is moot.

Contact http://www.magazineblocks.com/ and see if they are looking into making blocks, or have something that will work.  I bought 2 for my 5.45x39 mags.

I can't even buy mags larger than 15 rounds. No one will ship them to NJ. If I go out of state an get them then get caught its a felony. And  as far as I knew I can't install blocks

A quick search of Magblocks site they sell an 7.62x39 block for CPD mags. But there's no way to even get any hi-cap mags into Jersey to legally do it.

Took the rifle to the range today, in fact I'm still here. The rifle doesn't function. Failure to feed, failure to extract and failure to cycle, it also does not lock back on the last round 90% of the time. I'm not sure of it's an oil problem or gas problem. I've currently packed it up and I'm going to run a few rounds through the Henry .357 lever action. When I get home I'll look at the 7.62 rifle.

With it being a piston kit, I wouldn't know where to begin with helping you.
Only suggestion would be to see if it will hold open on 2rounds in mag, feed 2 and lock back.
If it won't lock back, open the piston gas, or open the gas port.
Good luck.

Yes with a piston. It would not lock open with two rounds and wouldn't feed on two rounds. Looked like it was short cycling. I had a stove pipe on the first round fired; looked like the bolt didn't move far enough back to eject the case.

The piston is set on full gas. I'm home now but haven't pulled the rifle apart yet. I'm going to check the gas system, maybe I got oil inside the piston and it's sticking or the carrier isn't lubed up enough. I'm not really sure, this is the first piston gun I've owned so I'm hoping someone with experience can hero me out here.

Pulled it apart, it looks like the piston was rubbing up against the snap ring and weld ring. I adjusted both and it seems to be moving smoother. I'm heading back to the range with my Buddy tomorrow so I'll report back here after I get home.

time to drill out the gas port hole in the barrel you can measure it first but I would drill it out to .92 to 1.09. I have a syrac piston kit and had mine originally at .72 and that's fine for 5.56 but not 7.62x39 drill that baby out and it will work great good luck man

So, what was the out come of this? Did you get it to work? I am in the process of gathering part for my upcoming 7.62x39 project. I am going to go with a Mid Length  gas system (Black Rifle Arms) which I am more familiar with.  Thanks for sharing your project.  I hope you got it to function reliably.

I too am planning a 7.62x39 AR, probably a clone of the colt 6830 ...my nephew bought an sks, and I like the round, however not a real fan of the SKS or AK .I have a flattop 556 and a flattop 308 and a few lowers to build....so an A2 style upper makes sense to give me some variety.......I have been reading everything I can, I don't care about having to tinker with the mags etc....all part of the fun, I have found one chrome lined barrel,  green mountain, not sure how I am going yet though, I will be watching this thread all the time.

I am wondering if the original colt barrels were the same barrel extension style as todays.?  I know some say the bushmasters and maybe windham weaponry had modified feed ramps?

trying my google foo but same stuff appears over and over.......

Never installed it. Its still sitting  in the package in the bottom of the range bag. Same thing with the reduced power buffer spring, never installed it either. Figured they'd be installed as processes of elimination.

I ended up drilling my gas port hole to .126", which is basically the same size as the interior dimension of the gas tube. My 20" 7.62x39mm AR finally runs now. Simply go slow, re-assemble and test until your rifle runs 100%.

Wow! That is a pretty big gas port. What gas system does your barrel have?

My carbine length 10.5" barrel Faxon barrel had to be opened from 0.81" to 0.89" and they now ship them with a 0.91" gas port. Yours seems extreme.
