Default AR in 7.62 x 39

I have a Zombie Defense stripped lower on order, should be here first week of May. I am considering putting a 7.62 x 39 upper on the lower I plan to build.

Who has experience with AR's in 7.62 x 39? So far I have only found information about Bushmaster and Olympic complete uppers. DPMS lists an upper on their website in 7.62 x 39, but there is no information available yet.

Considering the 7.62 x 39 because I already have a 5.56 / 223 and just want to have something different.

Great concept, poor implementation. The taper of the round makes it very hard to get to feed reliably in a standard AR mag well. Where the mag seats, there is no curve, which 7.62x39 needs in order to function well.

44Mag.com has the CProducts mags for a pretty good deal, though, and they are the best of the 7.62x39 mags afaik.

I'd go with another caliber, but the decision is yours.

Thanks for the quick reply. I don't want to drop $500.00 plus on something that does not work.

There are other calibers I am interested in, but ammo is so expensive, e.g. 6.8SPC.

Of course buliding another 5.56/223 would fit the KISS concept when buying ammo.

How about .300AAC BLK? I'm thinking of doing one for my next build.

Or, you could do a 9mm. They are a LOT of fun.

I went w/ C Product mags and had good success. Well once they exchanged the ones
I initially purchased for their current gen mags.

Ar15Performance.com makes a great system in 7.62x39. Their bolt takes care of some issues caused by lack of material in key areas.

I however wouldn't do x39 again. I'm currently waiting on my .300 blk barrel so we'll see how that goes.

As far as curring your desire for something different why not try a different combination/style of 5.56 AR. Maybe try a KISS style. or how about a super light weight? Maybe a precision build or a build geared more towards a combat use rifle?

Its easier keeping your ammo selection to a minimum. Its cheaper as well.

I've heard all the same things, but I would love to get my hands on one just to see what it would take to get it to function properly. 7.62x39 is a cool (and cheap) surplus round that would really add to the AR's potential ...If it could be reliable

All you need to get a 7.62x39 to function properly is the number to ar15performance.com and give C Products a call for some magazines. Once I recieved good mags it functioned 100%.

I was going to echo some of what mjkeat has posted.

The 7.62 x 39mm is a powerful, POWERFUL round inside of about 200 yards. So for a multifire weapon with multiple rounds on target, it's going to do the job.

The problem is, unless you are building a street to street, urban battlefield rifle, it's going to present "issues" in reliability and accuracy.

The ammo isn't "spec", which means it varies quite a bit from lot to lot and sometimes round to round in a single shot, precision category.

If you have a want for this type of rifle, your big issue is going to be tuning the weapon in the following categories:

1) Uneven ammo pressure

2) Feed ramps

3) Magazines, Magazines, Magazines.

Those three categories are going to be key to building a reliable, accurate and consistent weapon.

Personally?

I would look at a different application.

If I were getting an AR it would for sure be in 6.8. The guys I know from Rock River Arms have convinced me it's the way to go. =)
