Bedding A Mossberg MVP

[Rollis R. Karvellis]

Good Morning, later today I will be bedding my new MVP. The accuracy, and precision just does not exist with this rifle. It makes a SKS look like an Accuracy International.

I plan to bed the portion of the receiver behind the trigger, and the front of the receiver, barrel lug, and barrel nut, my question is should I also bed the exterior of the plastic magazine housing, and if so should I also bed the top of the housing where the receiver lays?

The stock is pillar bedded, but there is a good bit of flex between the action, and the stock. Also the screws will not keep the 50 inch pound setting I have been trying to maintain with it.

Anyone else have this dilemma with the MVP, and if so what did you do?

Once I get to the plant to load, I will try to upload photos of the disassembled parts.

Thanks.

Sorry I'm no help on the bedding, but I'm curious, which particular model of MVP do you have? I've got the 20 inch 5.56 Predator, with the laminate stock and it's a real tack driver.

I thought the MVP was already pillar bedded? Doesn't it have a bedding block already?

Pillars only from the one i looked at.

I think bedding might be the ticket, first tho check to make sure your action screws are actually contacting the pillars in the stock and not getting hung up on the stock itself.
Then do the same for the pillars and action.

If your screws are contacting the stock relieve them and try again.

If your actions contacting the stock before pillars relieve that and bed the action as you were thinking. I would avoid getting bedding on action nut tho.

I would check the action screws as was suggested, and make sure the barrel is free floated (I had to sand the barrel channel on mine). My Mossberg MVP Varmint 24" is MOA with Hornady 55gr SP, and sub-MOA with IMI 77gr Sierra OTM when it ignites the IMI primers (need to figure out how to get it to reliably ignite military primers or send it back to Mossberg for that as it is chambered in 5.56 so it shouldn't have a problem with thicker cups.)

"...The stock is pillar bedded..." That means it's already bedded and glass bedding it won't help. No bedding the exterior of the plastic magazine housing anyway.
"...the screws will not keep the 50 inch pound setting..." 50 in/lbs. may be too much, but that indicates an issue that should be covered by the warrantee. http://www.mossberg.com/category/series/mvp-series/

Sorry for taking so long to get back to this thread.

The pillar used for this rifle are little more than than thin sheet metal rolls. So my bedding job was at the tang, and recoil lug, while avoiding getting any bedding on the plastic mag well.

The long and short of it is the gun is more stable than before, and was a fun little project, but it is an inch and a half to two inch rifle using my match loads that I have tried, and a little over three inches with 147 grain ball.

The final target is fired prone at 200 yards with a 168 grain load that I have used for years.

The sad thing is that my Remington 700 Long Range in 300 RUM that in theory should be a superior rifle has sloppier fit, and finish then this one.
