In my opinion,you have 3 choices.
1.The H-S precision stock.This is the most
Reasonably priced of the three.They start
at around $250.00 and go up from there.
2.The Mcmillan stocks.These are my favorite,
especially if you want to duplicate
a M40 (marine sniper rifle).They do need
to be installed by a competant gunsmith.
Expect to pay anywhere from $400.00-$600.00
3.The new stocks made by Accuracy Int.These
duplicate the stock they designed for Their
own rifles.They are made of aluminum and
plastic.I saw one and was impressed.They
cost about $600.00
Bottom line-any of the 3 will work fine.Just make sure it is installed corectly.Even the H-S,which is sold as a "drop in" should at least be bedded in the lug area.And the last thing I would suggest to anyone looking for a stock is to not bother going for some potentially expensive extras-namely an adjustable length of pull.This feature was designed for use on weapons that will be used by several users,who have different L.O.P's.Looks cool,but can add a significant cost to your stock.
Good Luck
