is it possible to convert the bolt to extract 7.62x51 nato rounds instead of 8mm?

I'm considering having a custom .308 bbl made by montana rifleman barrels for the rifle and the bolt modified to extract .308 rounds. since .308 is a bit more economical, affordable, accurate and more abundant than 8mm is. and I can reload .308 a bit better and get better results in accuracy on the range.



I figure that the thing that is really needed is a .308 extractor for the bolt and a .308 bbl and I should be set. I believe there are .308 20 round yugoslavian magazines available for certain m90 RPK rifles, and I don't see why they shouldn't fit the 8mm slot with a little modification or customization.

Not to sound harsh but IMHO that would be stupid. You would destroy the value of that gun in a heartbeat by putting a non original barrel. Also, 8mm is dirt cheap right now. Look around and you will find Romanian surplus is the deal going. You can buy enough 8mm now that you will wear out the barrel first. If loading is your thing, then get some virgin brass and do some custom reloading.

uhm, well this wouldn't be a factory m-76. we're talking about a CLONE built using a parts kit. there is no value in a kit gun.

They have a .308 Preban M90 on gunsamerica with a buy it now of 2,000. That would be your best route. Then you could sell me your kit for the heads up.

8mm is dirt dirt cheap keep it original. Gun is worth far less after a conversion like that. If you want an AK type sniper/DMR get a Romanian PSL. 8mm is a nasty piece of work too just learn its ballistics.

Heres a PSL they go for around $700 about 1/2 the price of a M70

Why not just buy one of the M90's in 7.62x51mm floating around out there......? You'll have an all original rifle without having to screw around with the magazines, which I don't think would work in a M76 receiver anyway since the length of the 7.92x57mm mags is a lot longer than the 7.62x54mm and designed differently.



cause I'm waiting for kits to become available. don't feel like spending $2k on an original when I can buy the kit for $500 or a bit more, a receiver for $100 and build it myself.

Hate to tell you but that wont happen. Last time I saw a kit it was 1000 started out around 700 and went up. Receiver is about 500, plus the building of the kit, even if you do it yourself. Custom barrel who knows exactly. Also if you call troy and have a custom receiver done there is now way in hell he will do it for 100. So you will have the same or more in that as the one I found for you. Good luck but I dont see were its worth or possible in doing what you mentioned.

no the STAMPED receiver is $100...... the milled m76 receiver is $500. I know that. he said yugo m90 in 7.62x51 said why not just buy that. and I said because it's $2k for the thing, so if I want one I just wait for the .308 kits to start arriving, get a stamped m70(.308) receiver and build my own. certainly would be a bit less. you misunderstood me.

I would assume if .308 kits ever reach our shores(which I think they will given how defunct the .308 m70 is now, although still in production by zastava I believe) one would certainly hope a manufacturer like DCI would be intelligent to build a receiver for it. I imagine they'd run about $100 even since they're 7.62x39 receivers are about $80.



wasn't even referring to the m76. and after what I saw the other day with a 24/47 rifle that did 1/2 moa groups with 8mm, I think I'll just end up buying the 8mm when I get the money. There was an old 24/47 rifle that did 1/2 moa groups with some kind of 8mm handload. need to figure that out. hold on lemme get you guys the link.

UPDATE: http://www.snipercentral.com/forums/viewtopic.php?t=3682

link to the 1/2 moa 8mm. I wanted .308 for the m-76 because it was more common and easier to load/buy.

as for the m-76, my idea was simply, replace the 8mm bbl with a .308 bbl, replace the extractor if needs be so the bolt will work with .308 and modify the magazine well to take yugo .308 magazines(as they're actually the same size as the 8mm mags, so it wont take much). so voila, I'd have a .308 m-76 precision rifle.

Voldermortist,

Anything is possible if enough money is thrown at it but IMHO, you are better off just buying a factory made Yugo model. By the time you get what you want built, you will have close to what could have been had commercially. In the end, your "custom" will be worth less than half of what you put into it if sold later.

Head diameter is the same on both the 8x57 and the 308. Nothing should have to be done to the extractor
