I've been trying to decide what I want in my next AR style rifle. I have a couple of Ak's so I've been leaning towards an AR in the same cartridge. Anyone have experience with these? Anything to watch out for? Any pro's or con's? Model 1 sales has a 16" dissapator kit that I like but not sure I want to buy from them

I am intrigued by a 7.62x39 AR as well.

I have read that extractors break alot and many mags don't work well. I haven't totally figured out what is happening, but you may find more info here: http://www.ar15.com/forums/forum.html?b=3&f=121

From what I understand, magazines reliability is a problem due to the top of the mag being straight to fit the AR magwell, x39 works better when the entire length is curved.

If you really want an American made 7.62x39 rifle, an AR may not be your best choice. You may want to go with a mini-30 with the 20rd factory mag and an accustrut (so it will group like an AR).
If you really want all the railed collapsing AR buttstock goodness, you gotta slap it into an aftermarket stock. I heard the ATI's are pretty good. The mini + aftermarket stock + accustrut will run you about the same price as or maybe a little more than an x39 AR. At least it'll be reliable.

Bushmaster sells a complete 7.62 x 39 upper for around $800. The only problems I've heard of people having is magazine related. I was considering buying an upper, but I'll just save up and get the Robinsion XCR in 7.62 x 39

I have three, using a Model 1 14.5" barrel with an LMT bolt and a Model 1 firing pin enhanced for 7.62x39, a Bushmaster barrel with an LMT bolt and a Model 1 firing pin enhanced for 7.62x39 and an AR Performance bolt and barrel combo using a standard firing pin. Obviously I like the platform.

Magazine woes, as well as those associated with lighting off the hard primered eastern european steel case ammo (Wolf, etc.), are a thing of the past. C Products new production 10 and 30 round magazines are readily available and work just fine, as do the out of production but findable USA 20 round frankenmags.

After my first one, since passed on to a friend, I sold my AK.

For some more info you can go to 7.62x39mm AR-15 configurations (http://www.ar15.com/forums/topic.html?b=3&f=121&t=373257) and this 7.62x39 FAQ (http://www.ar15.com/content/page.html?id=558).

I've been running a Model 1 7.62x39 upper for a couple of years now. I went with the MGI Enhanced Bolt and firing Pin, since Model 1 wasn't offering their 7.62x39 firing pin back then. The early magazines were a bit problematic back then, but the new C Products mags are running fine for me. I must have over 4K of rds. through it and it runs flawlessly.

Great news. I would love a 7.62x39 SBR. The 7.62x39 performs well out of a shorter barrel. I might have to rethink it now that the issues are worked out.

This.

That is the exact same thing i was thinking. Costly, but awesome guns.

I bought a bushmaster last year when they first started make them. Mine had to be sent back for a little tweakin on the feed ramp but with c products mags it doesnt miss a beat now.

The Bushmaster's feedramp is a little different:

Mine had a little misfeeding to begin with, but after about 80 rounds it left that behind. I attributed that finally to just new gun crankiness.
