Things I liked:The front mount fits on the rail and locks in place. Things I would have changed:Although fairly self explanatory, there are zero instructions with this item. The very small allen wrench provided, may tighten the front mount to the rail, but will not remove it without breakage. Maybe a small amount of lube would help, but no instructions to state so. The rear mount does not fit the rifle if any modifications have been done to the butt stock. This should be a part of the write up so these are not purchased by folks that have done mods. There is no place to install the butt stock mount if mods are done! What others should know:You will need to buy a different butt stock insert in order to make this work if modified but stock has been installed.
Things I liked:Of course that it's adjustable. It is made in USA. Things I would have changed:Might consider a two bolt scope ring set up. What others should know:This is my second adjustable mount, the first worked great, this one had some burrs along the inside that would not allow adjustment until removed. I'm guessing one poor QC slipped through as the first one was perfect. The instructions could also be slightly more detailed. You also might consider, as I did, applying a small amount of grease to the screw threads before assembly in case disassembly later is needed. Overall a good solid product that does what it's supposed to do.
