$400 for a SLR-95 is a good price. Ironwoods sells a stock kit that includes the buttstock mounting hardware. This mounting hardware replaces the need to install the lower tang, and it is very solid. It's also very easy to install.
The cost for the Ironwoods set is $90 shipped, RSA trigger for $59, and you are set.
The SAM-7S is an excellent choice, especially if you want a scope rail.
If you dont care about the scope rail, cleaning rod, and want to customize your rifle the SLR-95 is a very good alternative.
Here is a picture of my converted SLR-95 with the Ironwoods set.
You will only need 4 US parts if your SLR-95 has no muzzle brake on it, and 5 US parts if it does. The milled receivers need one less US part to make them leagal than the stamped receivers. Stupid laws.
