    Since,
    My rifle was returned from
    Mossberg repair. I have no
    Issue with misfires, probably
    Because new barrel
    (Headspace ?)
    Trigger works fine. Doest
    Go into safe every other
    Round.
    Scope rail is aligned
    Good , not 6 mil to left.
    But when I first fired this
    Rifle I would hear a high pitched
    Vibration sound, like
    Metal.
    Same thing yesterday at
    Range.
    Does this rifle have an
    Issue because metal
    Action is bolted to
    Metal stock.
    Should action be bedded
    To isolate metal to metal
    Contact ?
    Does anyone hear this
    Sound , with same rifle ?

    Depends on what all furniture and accessories are on the rifle. The AR buffer tube being hollow helps to make a sort of resonating ping on mine upon firing. I've skim bedded the action and fully bedded the recoil lug now which didn't have any effect on the sound but it wasn't for that purpose. Make sure everything is snug, hold the bolt down and shake it like a crying baby and check for clicks or rattles.

    I already checked the bolts
    They tight. Must be 80lbs
    Or more on them from factory
    Repair. Didn't shake it,but will
    You bedded yours for
    Precision I assume.
    You do it or gunsmith ?

    Yeah, I shoot long range precision matches with it, they're very similar to PRS. I bedded the action with my coach in an evening. It's easy as pie. Sand/grind the bedding block everywhere were metal pieces are meant to touch with good low grit paper or a dremel down to bare aluminum. Remove the bolt and trigger assembly and spray the action of your gun with Pam cooking spray to get an even coating that doesn't drip but is thorough. Mix your steel epoxy and hardener, slather a thickish coat on the horizontal bedding block surfaces and fill the recoil lug cavity about 3/4 full. Drop action in and snug down with action bolts (not super tight, just good and snug). Wipe off excess squeezed out epoxy and let the gun sit to cure the rest. Pull the action out, clean off the Pam, reinstall your trigger and bolt and you're good to go. Tighten action bolts to 65 inch pounds. Don't over tighten. The gun will sound more solid afterward. Acraglass by Brownells and Devcon are your best bets but many 2-part steel epoxy's will work fine. I don't recommend JB Weld. It's a bit brittle.

    That's whole rifle vibration imho. I can feel it and sometimes hear it when I slap the side of the butt stock on some of the rifles I had.

    Spamassassin,
    Sounds so simple
    I definitely can do it.
    It has to make an improvement.
    I just watch a video , doing
    Pretty much exactly what you
    Explained.

    Also
    Do you use the mvplc for
    You competition shooting ?
    I understand its more an entry
    Level rifle and medium range?
    What weight bullet do you use
    For the 1:10 twist ?

    I use a MVP Varmint .223. It's a 9 twist 24" barrel model. Originally it came in factory wood stock, I later bought the LSS before the LC model came out. Yep. I use it for competition shooting. What it's good for is what you make of it. I shoot to 1000yrds with it in competition and do well against the rest of the field. I'm usually the only .223 and I'm always the only MVP. Yeah, it's not made specifically as a precision rifle but it's easily adapted and if you handload you can get really impressive accuracy from them with little effort. I wouldn't call it entry level or medium range. That's a function of the shooter, the scope and the ammo more than the rifle in that the rifle is up to snuff to be a modern mass produced and surprisingly accurate little gun.

    Here's a whole playlist of videos of me in matches and doing informal long range shooting:


    With the factory barrel I started with varmint bullets and steel case/steel jacketed stuff. After a couple thousand rounds I went to match shooting with it and adopted Berger 70gn VLD's and Hornady 75gn HPBT. I also shoot Savage rifles, both custom and mostly stock, Winchester rifles, Mauser rifles, Sako rifles, Anschutz rifles and Remington rifles in various competitive forms. Most of those are more refined designs with less compromise for cost of manufacture but they're not much better shooters. My smallest group ever came from my MVP.

    The barrel on mine is shot pretty well out now and I'm waiting for a new pipe from Columbia River Arms/Black Hole Weaponry. 26" of 7 twist yumminess and now with the ELD-M's available for .223 I expect my scores will pick up a good whack. Hoping to crack that course record in the Spring.

    it's a 2.5 hour drive both ways on the best of days but yeah, that's the only thing that makes up for basically every kind of gun you might want to actually own being illegal, unobtainable or a registered assault weapon, whatever the hell that is.

    Tell me about
    I used my savage hunting rifle
    With iron sites for years
    Then when I wanted to get
    More Into shooting
    I found out I couldn't buy anything
    I wanted because of these
    Stupid liberal laws , that only
    Stop me from buying a certain
    Rifle. You know someone
    Who served his country, never
    Got anything more then a
    Parking ticket and worked
    And paid taxes for thirty
    Years. Like the criminal or
    Terrorist cares about
    Gun laws.
    Bolt action are great for
    What I'm doing, but I also
    Wanted ar15 semi and
    Its illegal.

    You can still go featureless. Not much consolation but there is that option. The Thorsden stock did a decent job and then you can use a real mag drop button.

    I really don't like the politically correct
    Featureless semi with the funny
    Stock or the ar15 style that
    You need to break open
    To load ammo with glued
    In mag. Not for me.
    I think I'm going to buy
    A rifle that I want in FloridA when
    Visiting relatives etc.
    I can also travel with my
    Bolt action to use on
    A shooting range (long range) about 2 hours
    From Sanford fl.
