I have a green Bell and Carlson stock in the M40 style. It is inletted for a Long action Rem 700 with a standard Remington Sendero/Varmint taper barrel. I used it with a #6 Pacnor sporter barrel and it fit really nice. It has 13 3/4" Length of pull for the longer armed fellas.
I had to do some minor inletting to free float the barrel and center it in the channel, otherwise it is in almost new condition. The aluminum block has never been bedded.
I'm asking for $200 shipped.
