View Full Version : 5.45 x 39 AR
I recently, against better advice, put together an AR in the 5.45x39 Commie caliber. Used all quality parts, some left over from other builds, and the gun went together very nicely. Oh boy, inexpensive ammo to shoot, hot dog. There was only one problem, MAGAZINES!!!!! After much shopping around and trying different makes, I thought it would be helpful to others if I made a list of the mags that functioned well. So, from my experience here is the list:
Nobody!!!!
Thanks for your time and allowing me to complain. If some one with more knowledge says "don't do that" it's best to listen.:fie:
wrong sections - check out "Beyond 5.56"

Hey Gunz-
In the future, may I quote you on the C-Products mags? Ive been using them for years now..ZERO problems. People go apeshit over them, maybe a long time ago they had issues, but mine haven't for at least 4 years or more.
If it's my build, any help would be appreciated. I'm not sure that my build has anything to do with the rounds doing a nose dive in the mag. I've tried various makes of mags and one thing i've noticed is all the followers are almost identical. The front of the follower is 3/8" long and the rear is 7/8" long. the Magpul 5.56 follower is 11/8" both front and back. The 5.45 followers are not self leveling or anti tilt, also the springs seem to be a little on the week side. Also I noticed that the feed lips do not seem to hold the rounds securely in the mag when near full capacity, or maybe I've just got 6 or so "Friday" mags.
Oh, I almost forgot, I took the rifle to a 'smith I've used for the last 12 years to check the gun out. His conclusion " the gun is OK the mags suck".

I have asc, c products, and some ar stoner mags from Midway. I've only had one magazine out of all of these that has given me trouble.
You will notice I stated "maybe its your build"?. Since you left out all kinds of details its anyone's guess. Newer production mags from ASC are fine in 5.45. I don't use any of their other stuff as there is no need. Maybe you have older ones which many will acknowledge were problematic.
You'll also notice aside from your magazine rant, you actually never described the type(s) of malfunctions either.

The rifle will fire 3 or 4 rounds then the top round will not feed because it will nose dive in the magazine. This is common in all the different mags. I also noticed that that mags feed lips do not hold the rounds secure in the mag when near capacity, this seems to be mainly true on the right side of the mag. The round on that side comes up at an angle the causes the BCG to not be able to feed it into the chamber. I know there is nothing wrong with the build (not my first build) because on the rare occasions that the rifle does feed properly there are no indications of any problems. I've, as a precaution, taken the rifle to a gunsmith and had him check the gun and my build, Because who knows , maybe I did do something wrong.Wouldn't be the first time. I had him also check the head space just to make sure that was OK. That leaves only the mags, and since the rounds are not making it into the chamber, I don't know what else it could be.
I recently bought a magazine from MWG, their 30rd IK-510 polymer AR15 model, I bought it for my 5.56 Adcor Bear Elite. I loaded it with 28 rounds of 5.45x39 and have fired 120 rounds though my 5.45 build and have not had any problems at all. I took the mag apart and the follower is their own design and it does not allow the rounds to tilt down into the mag. It also has a "substantial" spring.
I'm glad that your mags work for you guys, but they don't work for me. I have at least a dozen ASC, C products and D H Defense mag for my regular ARs and the all function fine. I was hoping for the same results for the 5.45 but it just ain't happening.
So as I recall, ASC purchases C-products. Notice I have not mentioned anything about C-products. The magazines I have are made by ASC. Have you contacted them and addressed the issue?
Again- you seem to be defensive about your build. I am not saying your build is the issue.

I have 6 of the C-Products mags and they work fine.
I have a lot of experience using 10rd Pmags, gen M3 I think. At first they'd only hold 9 but eventually they loosened up and hold 10. I haven't had any feed problems with them. Windowed M3 Pmags seem to work well, but for some reason the non-window ones don't. I trimmed the front of the follower, and it seems to work well to around 25rd.
Take the mags apart and take a small file or emery board to the followers. Smooth out any rough edges or sharp angles. Put the mags back together and take a yard stick or other long instrument to compress the follower on the spring a few dozen times. You should experience no hang ups. If this is the case try out the mag and see if that helps. Once I do this on my 5.45 mags I have no issues.
I have some older C Products, not ASC, mags. I want to say they're at least 6 or 7 years old. Pretty much always had some issues with a few of them. I have knocked the corners off as listed above but still actually broke the back end off one of the followers trying to cycle it as described above.
Mine are finished in a shiny black teflon over stainless, inside and out. I was sure there would be something inside of the bodies but they're all seriously slick and smooth. I've had problems with the springs simply not having enough force to feed the last 4 - 5 rounds or the follower just getting stuck inside the body. I don't think any of them will drop free from the rifle either. I think at one time there may have been issues with the mag finish, maybe that's what I have.
The stock springs didn't have very many cycles on them but I've replaced them with Wolff AK74 springs cut in half. I finally have them all numbered to sort through them. I figure with the end of 7N6 we won't be seeing anybody else jumping into the mag business, got to find what works for you.
