    I'm getting ready to build my first AR but due to the cost of ammo I was thinking about going with the Russian cartridge. Can I get someone opinion. Thank you.

    Stay away from the 7.62X39. It doesn't feed reliably in the AR platform.

    If you plan on shooting steel cased ammo they will be within pennies per round. 5.56 , more accurate, better distance and readily available here in the US on every shelf

    if ammo cost is foremost then check out the 5.45x39 readily available at lower cost than 7.62

    When comparing apples to apples, steel to steel, and brass to brass they run the same in price. In fact the non corrosive brass 7.62x39 ammunition I've seen costs more than its 5.56 counterpart.

    U still can get the .223 by using Wolf or Tulammo brands. They are russian made and steel cases. Some users are happy with both brands. But my DD jams with Tula.

    I lube my guns with Mobil 1 5-30 Synthetic oil just like i put in my cars. Any buffer tube will work just fine.

    Might be to heavy. Try a H or carbine. My DD run great w/ Tula 62 and 55. I use a VLTOR A5 receiver extension.

    Are you using the AR for any special purpose?

    The only reason I was looking at the 7.62 is because my local LGS has Russian surplus at 50 rounds for 12 bucks
    But with people saying it might cause some issues I think ill stick with the 5.56

    I think some link a RRA dedicated 7.62x39 lower that has a magwell designed to accept and feed the round. Looks reayll interesting.

    I had a x39 AR that I eventually got to work. I had an ejection problem then a hammer that was to light. Once those two things were remedied it was a joy to shoot. The only problem was at the time the local ranges didn't allow bi-metal ammunition. I can shoot .300BLK brass cased for less than x39 brass cased.

    I tried going with a 7.62 X 39 cartridge for one of my rifles. The magazines were always double-feeding so I canned that idea. From now on I only use an AK type rifle for my 7.62 X 39 shooting needs. About the only other idea to go with for this shooting goal would be an AR-47 rifle. Those rifles use AK magazines set up in an AR lower. The AR-47s were popular with the SEALs for awhile.

    Wow! I didn't know that you could get a S&W AR47 until just now. Dang it. Now I've got to save up for a S&W lower that uses AK magazines so I can try that system out.
