Which EOTech was that?

i have a 516 i believe. did my sub moa work with it resting on some bags though

Couldn't have said it better myself.

If you really want one, and really want it "110% reliable", I hope you have magical powers. No matter who builds it, and with what parts, the magazine/cartridge geometry issues won't go away.

IIRC there were some companies making AR lowers that accepted AK mags, which was probably your best bet. However, they seem to all have gone out of business which doesn't lead me to believe they had much success with their attempts.

i dont know to much magic but my smith sure does. if it gets to out of hand ill just throw a few goats on the alter. iv seen those lowers befor if i could find one id give it a try but im making use of what i got available. and from what i hear mags have improved quite a bit

and still no answer to what buffer i need lol. i would like to hear from someone who actually has a 7.62x39ar

anywho thanks for all yalls input

Alibi...I don't own a 7.62x39 AR. I just don't like the problems associated with them. So, you've got me there, I guess.

I have, however, been around them plenty. Violent and over-gassed would be my way of describing their function.

Obviously, a heavy buffer is going to help some. If you're serious about this, a rifle extension / buffer would likely be the best bet. A VLTOR A5 would also be a good idea. Otherwise, an H3 buffer would likely work best if you want a carbine length buffer spring.

But, again, that was only my experience. And I know nothing about the barrel you have selected. You should talk to them about their gas ports. If they're on the small end of the spectrum, you might get by with a standard carbine buffer. If not (and this is more likely), you will be better served by a heavier buffer.

The reality is that since there's no standard for 7.62x39 AR's, you may end up having to do trial and error to determine what buffer works best.

ok i appreciate the advice but-
1. i dont want 300 blk or 6.5 or any of those rounds i want 7.62x39
2. i dont want another ak, if i need one i can grab the one in my truck or the couple i have in my safe. or even my mini30 would do the trick
3. i like 7.62x39 and it ballistics better than 556. nothing against 556 but im a 30 cal kinda guy

Fair enough.

4. im not to concerned with the tapered case since i have a mid length gas tube it should let enough pressure out to ensure reliable operation.

The reason the tapered case is malfunction prone has nothing to do with the gas tube length, it has to do with feeding.

5. if it proves to heavy to carry then i dont need to be carrying around a rifle lol.

I could carry an m60 just fine, that doesn't mean I choose to carry around a 25lb weapon.

- from what i understood from what iv read is the tapered case is a problem because of case expansion in the chamber making it hard to pull out and the taper also makes it tricky in the mags.

-true true, but i can alway swap in something lighter if i want, but im using what i have on hand

if i did get the pig id have my barrel turned down to 13 inch bringing all to 16. so it would be a short barrel like its intended for.

Just because Uncle Sam says anything under 16" is "short barreled" doesn't mean the Noveske Pig is going to be beneficial. Its a bad idea because the pig pretty much only has a benefit when used on less than 11.5" barreled 5.56 carbines. Let alone a slow velocity round that burns its powder fast.

But hey man, you can put what ever the heck you want at the end of your barrel, I'm just stating my humble opinion.
