RE: Questions about modifying Rem700s
Man, every one is making this far more complicated than it needs to be.
Yes, buy the gun and then buy a replacement stock for it. Remove the rifle from the old stock by unscrewing the action screws and put the rifle into the new stock and screw it back together. It's that simple.
There are piles of drop in, screw it togetherstocks for the Remington 700. Factory Remington synthetic stocks sell for less than $100 in black or camo, Boyds, Hogue, HS precision, McMillan,etc... You can even look out on Ebay and get a used wood BDL stock for less than $40 or $50.
There are really only two things that you need to know.
The first is what kind of 700 you have and you already know that. You said BDL. That simply means that you have a hinged floor plate on the bottomso you would want to buy one that is machined for this floor plate. BDL, CDL, SPS are all the same as far as the stock is concerned.
The second is determine if it is a long or short action. 243, 7mm-08, 308, WSM's, etc... are all short action cartridges. .270, 30-06, 7mm Rem mag, 300 Win mag, etc... are all long actions. Purchase a stock that will fit which ever one of the two lengths you have.
