I bought a Mcmillan stock (used) for my rem 700 short action receiver. Problem is, the hole for (i have no idea what its called, but you can see in the pictures what im talking about, about an inch wide, half an inch deep, 1/8" tall) is a little too small to stick my receiver in. it feels like its about to go in, and feels like i could wiggle it in somehow, but I cant! It seems like it should be about .05 inched wider than it is. Should I try to file it down to make it fit? or something else? Thanks!

The stock you bought had been bedded for another receiver, no big deal, you should try to clean it all out and bed yours. I am not sure how to clean it out but someone will chim in here.
 
I think you're talking about the recoil lug. Your stock has been glass bedded by the previous owner and his recoil lug might have been a little thinner than yours. If it doesn't fit you'll have to file it a bit. File the side towards the muzzle so your recoil lug will still have a nice, even, flat surface to rest on. Or you can enlarge the whole slot and re-bed it.
 
Thanks for the advice :) only thing is, this isnt a fibreglass bedding job, its some type of epoxy/resin? black and harder than the glass bedding i'm used to
 
I would go plan A, forward of the lug :D but just inside, not where the barrel sits.
Take a long shafted dremel and run it back and forth inside the forward part , may not get all the way to the edge, can use rough sand paper made stiff by folding.
 
Reality is

you should remove a tiny bit of the bedding on the entire surface. and give it a skim bedding with your receiver. That ensures a proper fit and support of your receiver to the stock.

It looks to me as that may be Marine Tex that was used for bedding. It is tough stuff.
 
Grind or mill the recoil lug open so your lug will drop in easily... Rough up all the bedding compound that is there and rebed.

There is no way a bedded stock will fit any other action than the action that it was bedded for.... You have to rebed.
 
Guntech is right and with good reason. You need to remove enough of the previous bedding so that your gun can be rebedded, especially in the recoil lug area of a round action, there is no other way. Unless you are a machinist, or you can guarantee that you will file a perfectly flat surface do not remove any recoil lug material. You could cause an incredible inconsistency that will hamper your rifle's accuracy. Bedding removal is greatly assisted by a dremel tool. And glass bedding is almost always epoxy of some sort, glass is just a stiffener like rebar in concrete.
And that specific bedding compound is probably marine-tech. Its supposed to be the best and is what the US Marines use to bed their rifles. I actually believe that the stock in the picture was one of the McMillan stocks on special that already served with the Marine core. If it is you got a great deal as well as a cool piece of history. You will want to get a dremel and bed that rifle properly as the Marine Rem700 actions were slightly modified and are dis-simular enough that it will need to be completely rebedded. Don't cheat yourself, do it right.
