Oh boy, where to start
They should all be accurate out of the box unless you get a lemon that snuck thru. The XR-100 is a single shot if I remember correctly so there's something to consider.
The VLS and VSF also have their differences. VLS doesn't have the palm swell the VSF has(some like the palm swell, others dislike it, I like it myself), it doesn't have the fluted barrel the VSF has, and it does not have the alluminum bedding block the VSF has. The stocks are different making the VLS the heaviest varmint model Remmy makes.
**NOTE: The VLS by design is not free floated. A few owners have said there's came free floated but it shouldn't be. It has a pressure point up by the front swivel stud. Some have removed that pressure point with positive results, others with not so great results. Mine shoots sub MOA with the pressure point so I'm leaving well enough alone
Does one make you drool a little more than another? If someone tells you looks shouldnt be a determining factor at all, they are liars. They are all known for their outstanding accuracy. If I were you, I'd be thinking about *single shot versus 5+1*, *price*, and overall *appeal/looks*.
The XR has the thumbhole which I love, I held one and putting it down and walking away was one of the hardest things I've ever had to do. I'd write more but just came off a 11 hour shift and need sleep.
Let us know what you decide on!
