Only one I ever had was a Remington 700 VLS with the heavy barrel. I talked to the Remy custom shop guys and they said the ONLY difference between that rifle and the Police "Sniper" was the stock. They just took the same action/barrel assembly and drop it in which ever stock you want. Saved myself about a grand!
The VLS is a good rifle. I had a Sendero (300 WM) when they first came out. I think the VLS and Sendero were basically the same rifles sans the barrel fluting on the Sendero.
