    Hello. I recently picked up a barely used Patrol 308 marked 7.62x51mm, to which I installed a Vortex Crossfire II 3-9x40 scope with Vortex Hunter medium height rings. I don't even think the prior owner ever shot it or shot very few rounds through it. It has no sign of wear and the barrel was very clean. Like New clean.

    I have yet to get out and shoot it but I have a few questions. I'm thinking of replacing the A2 flash hider with a Surefire Procomp 7.62 muzzle device. I am experienced in replacing them on AR15s however not on a bolt gun. Is there a step by step procedure and / or video on this? i have a vise but no barrel action blocks.

    Another question is the factory stock. It appears to be painted / textured wood. I thought it was synthetic. Should I replace it or hold out for Magpul to make a Hunter stock for it?

    I know I will have many other questions but I figured I'd keep it to two for now. Many thanks in advance.

    Hi and welcome to the boards.

    The muzzle gizmos change just like any other. When I was playing with them I used peel washers to index them so that they would dial in at just over hand tight. Lock washers always looked funny to me and crush washers need to much torque for my liking.

    Your stock is epoxy sealed straight grain Birch. It's a heck of a lot stiffer than than injection molded plastic stocks are.
    It's not the prettiest but it is one heck of a stock.

    So just clamp the barrel and have at it? Whats best to use to not mar the barrel? I heard Mossberg puts the muzzle device on pretty tight.

    Some use wood blocks. I use aluminum vise jaws and a bunch of blue painters tape over 2 tight wraps of card stock. Get it good and tight in the vise. The aluminum will deform long before the steel so really lock it down but don't gorilla the thing. When you get the wrench on the muzzle device it might be useful to give it a solid whack with a rubber mallet. Not sure if Mossberg uses thread locker on the muzzle devices. The lads probably know.

    vise jaws:
    These are what I use.

    These look neat but I haven't tried them.

    Many thanks. I will hold off on swapping the muzzle device until after I shoot the rifle and a bit more research on what to buy. Work schedule is keeping me from the range and I still need to buy a nice assortment of ammo to try. I do have a good stash of PPU 7.62 NATO FMJ M80 on hand but I'm not sure what accuracy I will get out of it. Another purchase is 10rnd Magpul Pmags for the rifle. Thanks again.

    Personal preference and it depends on the look you want. I went the jam nut route so you don't have to play with different washers to get the brake to time right. I went with a slant brake that gives about 40% recoil reduction, which was about right for me.

    I went with a 3 chamber muzzle brake. Sucks for anyone on either side of me but works well for recoil reduction. I quite like the stock.....stock. But that's a very personal thing. That Vortex scope is a good option.

    Anyone know where I can get an appropriate jam nut for my MVP 308?

    If you are talking about for the muzzle brake, it's a standard .308 threading. I think I got mine from Brownells.

    5/8x24 is standard for .30cal muzzle threads.

    For a brake, cheapo's sucko. The secret sauce to a brake being effective is in the first baffle. If there's much more than .020" clearance to the bullet (.040 total) you rapidly lose effectiveness. I go for .020" total clearance which leaves .010 all around the bullet. Makes for a very effective brake. The best you can get are JP Recoil Eliminators and Holland Side Discharge types (holland design is copied by hundreds of outfits). If you want the single most effective and well made brake currently crafted by anyone, anywhere in the world then you're looking for a Tresamax which are made by Dean Maisey in New Zealand. Dean is a great guy and his brakes are ridiculously well made and effective.

    I already have a Surefire PROCOMP 762 on hand but I was asking about a jam nut to use with it.

    Spam answered you on the size and thread. IIRC, the Procomp is supposed to be a pretty good brake.

    Woops, my bad. I found a JP Enterprises jam nut in that thread at Brownells. Thanks for the correction. :)
