M40 specifications ( remington 700 )?

im trying to build an m40 and all i know for a fact is its a mcmillan stock ( using a aftermarket if i can find one) and i also know that the trigger is dialed down to 3 to 31/2 pounds. but i was wondering if anyone out there knew the specifications beyond that such as...... bull barrel or glass bed ( which i should use i know the m40 is bull barreled but im not try to spend 7 grand on it) also a scope recommendation.... right now i have a 150 dollar scope on it i got from ***** but still looking for someone who can list all the specs i need and places to purchase things such as the stock at an aftermarked price ( 600 bucks maybe ) and of course i mean an aftermarket stock.....thanks
