I just bought a remington 700 sps varmint in 308. After getting home I found a plastic stock that is not free floating. The gun has a hidden mag. like the old ADL but has the heavy varmint barrel. I can not find a replacement stock for this exact setup. I believe it would have to be a rem. 700 ADL short action with heavy barrel specs. Any help on where to find a replacement or how to fix the existing one would be very helpful. Good news I only paid 450 for the gun!
