    Does anyone know
    Any barrel makers
    That can make a new
    Barrel for the mvp lc 7.62

    I was thinking of a 708 with
    26 in barrel.
    But no one makes a
    Barrel to fit.


    I was looking for completed barrel
    To screw on to my action wit
    Same barrel nut.

    Guess I have to sell it ?

    Some where here I read somebody put a Savage Barrel on their MVP, maybe that's a start? Good Luck

    Supposedly you can use a Savage small shank barrel with a Savage nut and MVP recoil lug.

    I will look into the savage barrel.
    Not sure why the numerous
    Barrels mfg, can't make a barrel
    With my threads for the 7.62 mvp
    I have never had a barrel replaced
    But never thought it would be this
    Difficult to replace my 18 in barrel

    They won't because they're whiny and too damned lazy to look at the bloody machinist drawing. Call up ColumbiaRiverArms/BlackHoleWeaponry, order a savage small shank barrel and enjoy yourself. CRA/BHW knows that savage small shank and .308 size mossberg MVP are the same tenon thread. You staying with .308?

    FYI, BHW/CRA has a shitload of reamers on hand for all kinds of stuff. You're not stuck with .308. Could do a 6.5CM or .243AI or oodles of stuff. If you just want a .308 tube you could buy my factory savage .308 24" threaded muzzle heavy barrel from my 10FPSR. I replaced it with a .243AI from BHW and won't shoot .308 anymore. It's got under 1000 rounds on it. Still like new. Have load data for stupid accurate loads.

    If interested in my extra .308 barrel, LMK. You'll get it for a song compared to a brand new one.

    What you'll need-

    Savage small shank barrel
    Savage small shank barrel nut
    Savage barrel nut wrench
    Go gauge for caliber selected
    some way to align the recoil lug when assembling

    Thanks guys for info
    I have 6.5 cm
    I wanted to go with 7mm08
    Found mcgowenbarrel.com
    Dan stated they can make a
    Barrel for my mvp lc 7.62 /308
    I can send action and 3 dummy
    Rounds in caliber I want.
    I'm not going hunting , or dragging
    It through the woods.
    So, heavy Target ?
    Muzzle brake threads 5/8
    26 in stainless?

    You're getting ahead of yourself, or us, or possibly both. Are you shooting paper or steel? What distance? Bench, positional or prone? What bullet weight are you aiming for? All of those matter.

    Mcgowen, shilen, BHW/CRA/, EABCO, NSS, and about 1000 others will happily supply you with a drop in barrel. None should "need" you to send in your action and almost none of them will want you (except maybe NSS if you're doing a shouldered barrel) under any circumstances. McGowan and NSS and EABCO all offer additional services.

    I'm curious about you sending in dummy rounds. Why? There's no need for all of that unless you're trying to replicate another chamber and honestly, that's a little bass ackwards. Chamber then load develop. Some rare cases like me needing a specific throat length is because I load long to get extra powder room for velocity without building pressures.

    As far as 7mm-08 all of the above can provide that barrel. Shilen has 2 different reamers that I know of, one is standard, the other is a .312 neck which would be best for a semi-auto as it's got .004" extra neck clearance for improved cycling.Their bolt action reamer is pretty tight.

    As far as tools & such, the man above had a good list. Mine's different: New barrel nut, 1 barrel nut wrench, 1 bench vise, 1 set of aluminum vise jaws for AN fittings, 1 rubber mallet, 1 brand new unfired (empty) 7mm-08 case (to set for zero headspace) for install. For removal, bench vise, aluminum vise jaws and a pipe wrench (monkey wrench) and a rubber mallet. I can swap a Savage/Mossberg barrel every 4-5 minutes set up like that. I find a little super glue holds the recoil lug fast to the action while setting up and knocks loose easy enough when you need to.

    Barrel length that's ideal will depend on the bullet. I'd look to 162gn ELD's and Berger 168's and Sierra MK 168's. With those look for 24" being the point of diminishing returns. 180's are too heavy for the little 08 case IMO. Velocity is crap. 168's and under do well. With 130's it makes a wicked deer killer but that's not your bag so ignore that.

    5/8x24 muzzle threading will serve you well. most brakes for this size gun are in that pitch.

    Stainless heats up slower in my experience but stays hot longer. Carbon steel heats slower and cools faster. If you're shooting long strings go stainless. If you're shooting cold bore then cooling down or otherwise slow shooting, go carbon. I prefer stainless for rifles when possible because all of my shooting is high volume, fast pace.

    Anybody know what the OD of the 7.62 action is? If its close to std Remmy/Savage diameter (1.350"), the Wheeler action wrench is a good investment for those who swap a lot of barrels. Its a ton easier with an action wrench. Once you get headspace right you clamp down on it and the barrel stays put while the nut gets tightened. I slotted mine so scope rails can stay on.

    Oh and if you don't mind the weight, full bull barrels (increased stiffness) are much more forgiving on load development. Or more confusing because everything shoots good to great instead of horrible to great.

    This was the response from Shilen
    "Sorry we do not. We can provide the barrel blank.
    Shilen Team

    I don't have a problem with sending
    In my action.
    I would have to find a gunsmith
    Here to install the barrel.
    If they do the complete
    Install ,I think that's fine.

    I only want to shoot targets
    Prone or setting. So heavy
    Barrel is great.
    Now I have to take
    Some time and learn
    About barrels.
    What other shooter's
    Prefer for distance etc.
    I'm new to all of this.
    You can only learn so much
    In two years.

    My mvp is just a terribly inaccurate
    Rifle barrel. Looks so cool
    Tactical, but bullets
    Go all over and I can't
    Find a load that's
    Works. If I fix it with
    Chambering it for the
    7mm new barrel good.
    If I don't rebarrel the mvp
    Will just sit or need to sell it.
    I really got tired of
    Going to the range with
    Fifty handloads . Starting
    At below minimum then
    Working up in .3 grains
    To just below max.
    I believe it's just a terrible
    Barrel.
    This was a big step up from
    My savage 99 with iron sites.
    Everythings tight. Torqued
    Correctly. Just a defective barrel?

    Call them up and ask for a savage small shank. That's what we're telling you. Shilen is uncooperative and disinclined to even look. Say the wrong thing and they lose their shit. One reason I stopped using them. The other was their barrels have become less than first rate compared to what else is out there.

    I bet your problem is the rifle's assembly is for shit. Not entirely uncommon with Mossy's. Before you rebarrel it, start by epoxy (devcon rocks, don't use JB weld) bedding the receiver and recoil lug and checking that the receiver bolts aren't impinging on the bolt, and are making contact with the pillars and that the screws for the scope bases aren't impinging on the bolt or barrel. They often are. Worst case, try a chassis stock and then start doing the harder stuff. It's almost certainly not the barrel. What state are you in?

    Remember I have the mvp lc
    It's a mdt-lss chassis.
    No pillers
    The chassis was supposed to eliminate
    The traditional bedding.
    I do believe in the mdt technology.
    The 18 inch Barrel I feel is an issue.
    I should have never bought a rifle with
    A short barrel ,unless it was an AR
    New York
    I will continue to shoot the rifle
    Shooting it next to my ruger precision rifle ?

    if you want fun with no frustration go 6BR. Best brass (75+ reloads not uncommon), wide availability of all components, best inherent accuracy of any .475" boltface cartridge, easy to get shooting great. The only downside is feeding from a mag but that can be fixed. Just get a Savage small shank 6BR 8 twist with either a CIP or 107g class bullet throat (very popular, ALL the barrel makers have this) and shoot everything from 55g varmint bullets to 108g long range target bullets.

    For the last 20+ years all the 600 yd and 1000 yd benchrest records have been held by a 6BR or 6BR based wildcat. And all the short range benchrest records belong to the 30BR.

    ^^^ pretty good option. Really great performing cartridge. I use 7BR and my coach uses 6.5BR but the base case is the secret sauce.

    OP: Epoxy skim bed your chassis and fully bed the recoil lug and remove and retorque (using a proper torque wrench and alternating stepped increases) them. Before we encourage you burn a lot of hundreds on a pipe I'd like to try and get you going as close to free as possible. However, you could just pitch that tube, true. In the case of ditching the barrel, look into 6.5CM, 6BR (6BRX is really cool), .260rem, .243win, .243AI, 6.5x47Lapua, 7mm-08 (I like that but it kicks a bit hard for protracted sessions at a bench), 6mm XC. Out of all of those the BR's are the most easy to nail a load with. 7mm-08 is going to have the longest barrel life.

    OP: Special offer. I've got a known good .308 Savage Small Shank barrel that I'm not going to use anymore just sitting here. 24", heavy, threaded muzzle, drops right in to your gun. 1/3 the price of a brand new one ($175 shipped and I'll leave the JP Tactical muzzle brake on it). Still has 95% of its life left. Group below is with Hornady 165 SST's at 100m. It hates speer 168's but shoots lights out with everything else so far.
