As Muskett has said, they're not the prettiest of rifles in their standard form but the accuracy obtainable is tremendous, which more than makes up for their looks.
A good friend of mine built a custom version. ISP made a steel moderator, glided the internals and fitted an Original 45 seal ( from memory ). With a bit of TP work he coaxed around 10.8 fpe out of it. It was all reblued and Warren make a custom stock for it which I chequered for him - it was beautiful to shoot and the rifle put in tiny groups without any real effort.
This was the plan for mine - but I really haven't got the time or inclination.
