    Question 8.mm m70

    Heres what's been rattling around in my brain when its not pushing hair out the top of my head.

    ORF has these m76 kits with no barrel or reciever but lots of other goodies.

    previous posts pictures and compairsons show that the differance between a 308 yugo and a 7.62 are in the bolt and carrier not the trunion which seems to be the case with the Faz family rifles.

    If you look at the chamber area pics you can see the .308 is not pushed as far into the trunion which give you the room for the extra cartridge lenth on that rifle.

    The 8.mm rifles look like they have longer recievers but that shoudn't be too hard to do.

    so the question is will a M76 bolt fit into a M70 trunion? if it does how hard would it be to do a M90 clone which is basically a stamped version of the M76/77 milled rifle. using M70 trunions

    I remember the comparison pics between the bolts, but I don't remember any from the trunions - maybe its the lack of coffee - can you confirm the trunions are the same? "as I recall"... the 8mm bolt had extra reinforcement and/or an extra lug...

    I'd have to search for that to be sure...

    the trunnion is same, I had the M76 bolt here, I am user M70 kits , M76 Bolt/carrier recoil spring , dust cover, you had use a Romak 3 80% blank receiver , be sure you get the long one, like 12.5 inch long ,because the bolt is much biger and longer , as for mag, you can use Hakim or M76.

    top is M70, lower is M76

    kits are out my toy budget right now but I'm thinking a 8.mm tabuk may be in my future

    Thanks, Bluejack! I couldn't find the old threads where this was discussed before.

    No, there was only the milled receiver version. That would also mean "without trunion" - if you can rebarrel a mauser barrel to fit then that would be something, but I have to agree this would be a bit on the pricey side for what it gives you.

    It would be a good source for the heavy bolt. Expensive, but that's that. May be good for the custom caliber builders...

    well, if you want, you can buy your a 30.06 Saiga , it has same bolt and face as 8mm, and maybe working the hakim mag into it, or like pookie said, there is a lot work and money.
    I am almost there, about 1/2 way, I had a masuer barrel fit and head space into M70 Front trunnion, now just need get gas ports and handguard working out, and big thing is receiver, don't know where to drill the holes , cause is different then romak 3

    The with out trunion part, is why I was wondering about the M70 trunions I have some floating around my garage. U.S. barrels are supposed to be avalible soon. the kit should have everything else. I was just thinking it could be an option to shelling out 5bills on an orf reciever. Also wouldn't these make it into the sporting arm classification?

    if the hammer and trigger are the same as the M70 wouldn't they just move back the differance in length of the longer bolt to maintain the hammer to bolt geometry?

    actually this is pretty close to what I was thinking

    Yes that is right, the whole trigger and hammer need to move back dude to the size of M76 bolt , and that is why you may want order a longer 80% coldsteel Romak 3 receiver,

    FOr what they want for the kit another $100 will get you a brand new assembled SSG-2000 in 8mm or 308 from inter ordanance. if you want it to look original the ssg-97 can be had for $749 with a scope in 308 or 8mm. they also sell plastic mags for the 308 for 39.95 for those guys who want to use one in a 308 conversion.
    the kit is $600 you will need a trunion thay are going for around $50 even Iif you alredy have one it still is worth something. you will need some US made parts figure $50 depending on what barrel you go with you can spend $10-$300. I bought 4 mauser barrels cheap on ebay once. but figure $45 for a good clean mauser take off. If you buy a reciver figure on $100 or so. you will still need a scope of some type to you would be lucky to be able to build it for under $900 that is a lot of $$$ to shoot cheap corrosive ammo that aint that great.
    Dont get me wrong I would like to build one as well just to say Ive done it but one can buy a lot of ammo for a 308 saiga or other gun. for the same money you can also ket a damm nice AR varmit build or browning bar 7 mag. if you do decide to go ahead with it I may have a good 8MM barrel left for sale or trade. I am looking for a few more Yugo trunions HINT HINT.

    I'm going for the 8mm in the rpk trunnion.

    M76 barrel here:
    https://www.apexgunparts.com/product...89ed354b1240fe

    The bolt will have to be modified and safely tested.
    This might be a crazy idea, but, regular bolt and carrier
    with heavy spring, smaller gas port. Regular length receiver
    (heavy CS yugo).

    I'm not recommending anyone try this, or that it's
    at all a sane proposal. Just rolling the idea around.
