I got one of these puppies and it is built like a brick Spit-house! Very nicely machined. Fits a variety of rifles, including some big stocks like my A-2. Found that for my shooting style the rifle is perched a little high at the lowest setting, so my friend did some surgery and he removed a bit off the arms, now the rest sits exactly at the height of a Harris BR and goes up from there. Unlike the Harris you remove the swivel stud, there is one on the rest that screws into the stock. Works fine, but makes for a pretty bulky forend. Can see it being nasty for prairie dogs, situations where you setup and sit for a while. Have not shot it enough to give you guys good field info - that is coming soon.
