Piston AR-15 in x39

[jason41987]

its in my opinon the AR15/M4/M16 design does carry a number of flaws with it, and unfortunately these people making new rifles to replace AR15 designs and people looking into getting into the custom AR15 market dont actually address any of them, but point blame at the wrong culprits

a very, very great rifle thats well battle proven and in my opinion one of the best "assault rifle" designs on the market, is the sig 551.. (i quote the term assault rifle because i dont like the term, but everyone knows what i mean when i use it)

that being said.. sig does sell a 551 family rifle in 7.62x39mm, and if im not mistaken you can even use dirt cheap AK47 magazines with it and it carries with itself the same expandable platform and ergonomics as an AR15.. best part about this rifle is you can use AK magazines which will allow the rounds to naturally curve in the magazine which will offer better feeding, greater reliability, and its a gas piston rifle.. i think it would be absolutely perfect for you and you should check it out online..

its called the "sig 556R"... check it out.. it should have everything you want without the problems associated with 7.62x39 in an AR15

Look into rock river arms. They have an ar in x39 that takes ak mags

if you want a piston driven Ar in 7.62x39 i dont see why you just dont get an ak or sks. itd make your life a good deal easier

few problems with this... first, piston ARs dont make an AR15 more reliable, they do in fact decrease reliability, and their only use is simpler cleaning..

Is there an empirical basis for this assertion, or just your sense of things based on what you've read/seen? Certainly some piston AR's have reliability problems.

I have a Olympic arms ar15 in 7.62x39 with the stainless bull barrel, and love it. It has the threaded barrel. With good ammo, it will shot MOA at 100 yds, and has been completely reliable. I bought it for hog hunting, and it works! One shot and done, works much better than my 5.56 I used in the past. I ordered a suppressor for it in April and have been patiently waiting!

Hey I have an Idea, let take an akm and fix it, put on a real milled receiver, a cold hammer forged barrel, take the crappy safety and put on a good one over the trigger finger. drop a pound off the weight, improve the magazines and make them lighter, make the bolt hold open after the last shot, and put on a bolt release. make it more accurate, oh wait we just built a vz 58! hah! see you in the vz58 club forum. ps Jason Im not shure about the piston version not being more reliable, all that dirty gas goes somewhere, and that was the jamming problem in 'nam.

oh yea! forgot take the heavy long recoil action out and use a short piston action just like what the ar bunch is copying right now.

Ar 7.62x39 with a few experiences from members who (not a piston) own one.

I use mine with 154gr sp for pig popping

My 556R solves the magazine related feed issues that plague the 7.62 ARs, but I've so far not found a solution to it not reliably setting off some lots of 7.62x39 ammo (can be as bad as 6 in 30 don't go bang). My 7.62x39 had the same issue too, but it was solved with a Model-1 Sales 7.62x39 AR firing pin for like $20.

For hunting, the 10 round 7.62x39 mags seem reliable, my feed issues always seem to happen in the fired shot count 16-22 range of the 30 round magazine. FMJ ammo and Wolf extra power AK mag springs seem to solve the issue, but with JHP I always get the occasional feed failures. So if hunting is your reason, IMHO forget about the piston and get a 7.62x39 AR if you'd not be happy with an SKS.

Hey Wally glad you chimed in. I have not had any problems so far with mags or firing pin. But like I tried to say I just hunt...10 round mags to save weight or 30 rounders if it appears there will be multiple targets.

I can honestly say that for me buying a vz2000 was the best firearm purchase I ever made. But everyone is different.
