Re: remington 700 sps tactical
I own an SPS tact is .223, of course the stock was replaced, I put mine in the Choate tactical stock (A5 type). It certainly tightened up the groups, but it is still a "decent" shooter. Nothing to get all worked up about, especially when you consider I had to spend an extra 200 bones for a stock that was worth a shit.
Save yourself the trouble, buy a Savage 10PC or Hunter Max in .223. You'll get a good stock that does not need replaced, a better trigger and a better barrel all for about the same price as the SPS out the door (before buying the new stock).
