    Looks like it. It's threaded 5/8" diameter and 24 threads per inch which is pretty much the standard for .30 cal muzzle threads.
    For certain my 7.62 patrol is threaded 5/8-24.

    The Timney trigger for the ATR 100 - is it the short action or long action trigger?

    Need some help from ya'll answering a question. Howa 1500 / Weatherby Vanguard, do the use the same trigger as Mossys 100 ATR and 4x4 ?

    Ken Farrell makes excellent quality Picatinny-spec scope rails.

    If you use a Smith Enterprise Vortex flash suppressor for your MVP 7.62, SEI makes 2 versions; one to fit a .635" threaded section and one to fit a .735" threaded section.

    The MVP 7.62 has a .635" threaded section.

    Hey all ... new guy here. I'm curious - has anyone ever sourced for the Weaver #51? The only lead I've found is to an older #48051 which seems to be four hole, 4" or so long mount for Marlin 336 guns. I also don't find a #51 in any of Weaver's catalog listings, so wonder if it's actually manufactured by someone else.

    Alternatively, has anyone tried the Weaver 35 as the companion piece used with the Rem 700?

    Following up - obtained a Weaver Base Pair Kit #48460, listed for Remington 700 and Howa 1500, and consists of a #36 and #35 mount. The #36 (rear) thickness is spec'd at .272 and the #35 (front) at .147 giving a difference of .125 in height back to front. I measured the rail for comparison and at its rearmost point it's .301 and at the front it's .183 giving me a difference of .118 in height back to front.

    In short, the #36/#35 combo slopes .007 more down than does the rail. That's not much, and given the direction would only serve to increase useful range a tiny bit. Given that the mounting curves seem correct (no light between base and receiver) and they came with the correct length screws I'm going to give them a try.

    In case anyone wonders why I would want to do this - the answer is that changing from the rail to the mounts will lower the scope by a bit approximately 3/16" which will help me get a better cheek weld without using a higher riser along with making it easier to top load a round into the magazine.

    Anyway, that's where I'm at - would still be interested to find the story behind the #51 mount I've seen pictures of here or there - oddly enough on 5.56 rather than 7.62 models.

    (edited to correct typo #37 to #35)

    The 5.56 MVP uses a standard 700 rear base same as the 7.62 MVP and Remmy 700.

    The 5.56 uses the same front base as a savage 99.

    The Front base of the 7.62 MVP is pretty much identical to the Rem 700 BUT....with the screw holes positioned differently.

    Both the #36 (rear) and the #35 (front) fit the screw holes in my 7.62 MVP Patrol exactly. Here they are installed. Excuse the poopy webcam pic but it's enough to get the idea anyway.

    Picture 83.jpg

    From what I can tell, the magical mystery "#51" is slightly longer and has an additional rail slot closer to the port. I've seen pictures of it installed on the MVP Varmint and Patriot Classic, but don't find any Weaver part numbers, even spoke with a Weaver distributor who said there's nothing similar to be had - perhaps it's made custom for Mossberg or something. Would try one if I could find one just for the extra mounting flexibility. Note that this doesn't really look like the Warne M902/877 combo either.

    Wouldn't surprise me if it were an exclusive OEM for Mossy only kind of deal. The 7.62 MVP and Remmy 700 short action are both the same diameter, length and contour but the the front ring is longer on the mossy than the remmy and the rear bridge is shorter on the mossy than the remmy too.

    I have the primary arms I think it's 4-12 with the 40 mm objective and medium rings
    I have no problems with clearance

    And a little more info - here's the standard #35 front mount (bottom) and a #40 front "extension" mount (top). The mossy part may be a hybrid of these - a #40 extension that also retains the slot from the #35.

    Also a "find" from XS Sights - Remington 700 - Ghost-Ring Rear Sight - with Integral Weaver Scope Base that looks like it just might work for the MVP as well.

    And now that Mossberg's building the MVP Scout, wonder if some party will be developing an alternative scout rail? I called support a couple of weeks ago and the nice lady there said Mossberg wasn't selling the base separately "yet".

    Hey Sanford can ya do us a favor ?

    Would you double check them both to see if they are identical except for length and then try out the #40 on your MVP an let us know the results ?

    Already done - they are identical except for length (and of course the location of the slot); both top and bottom profile are the same (the 40A is listed as a Rem 700 part). I've already used the #40 on my MVP with a scope that wasn't quite long enough to reach the front mount otherwise. When installed the #40 extends about 1/16" (judging by calibrated eyeball) past the edge of the receiver port, and has no effect whatsoever on function (ejection, etc.).

    Hope it helps!
