7.62x39 mag problems...

[TOrrock]

When Colt released their 7.62x39mm carbine in the late 80's/early 90's, it came with two 20 rd. AR mags with a follower for 7.62x39mm.

You could put 8 rounds of 7.62x39mm in them before you had serious reliability issues.

If you want a 7.62x39mm AR (for whatever reason), that works reliably, try to find a KAC SR-47.

Otherwise, buy a 6.8mm SPC, or 6.5mm Grendel.

Thanks for the information, Templar. I was wondering why the mag companies didn't just reduce the round count. It makes sense now.

So once again we resort to......

warsaw rounds for warsaw guns

nato rounds for nato guns

I had high hopes for my Colt 7.62x39 back then but was nothing but a headache and money wasted. Sold it to a buddy after much frustration, he knew the issues but just wanted it for hunting and didn't mind the 5 rounds. He still has it and has killed many a deer and some pigs with it.

Yep, pretty much. One exception being the AK & 5.56 or .223

Interesting 'Only seven rifles are known to exist. Six went to USSOCOM and one was retained in the Knight Co. museum.'

Now that has to be a collector's item $$$$

If only Magpul wouldn't have Bushmaster'd the Masada. I had really high hopes for the 7.62x39 variant that used AK mags I kept hearing about...

I found that slight extending the feedramps on my 7.62x39 AR helps a bunch. I can actually load my 25rd Grendel mags with 20rds of x39 and it works fine. If you use a dremel with a green grinding "cone" and make the ramps a little deeper, perhaps 1mm, it'll help significantly. Also you can order stronger springs by Wolff for the mags. 5% stronger and they'll make a difference when loading the CProd mags. Note that the CP mags are listed as 30rd mags, but in practice they really stop at 28-29rds but loading them to 25 makes a difference in reliability.

MGI has an AR lower with interchangeable mag wells.
There is a version that can accommodate AK mags.

I have a Special Weapons lower which takes AK mags.

That is only part of the problem. The other is that the bolts don't last. Full auto, suppressed, 10 inch - I was getting 200 rounds per bolts. A longer barrel without a suppressor - might last much longer but I would never trust it for serious use.

7.62x39 did not work out for me.

I also have a Colt but never used it much.
