Things I liked:I bought this scope to upgrade from my Tasco 2-7x32 and wow this scope was big. But fit good on my R9. I think that my Tasco scope opticts are a little better but for the price you cant beat it. Things I would have changed:The AO is a little stiff to turn hopefully it will get easier. What others should know:All in all this is a good scope for the money.
Things I liked:Replaced the seal and gun shooting back to normal all is good. Things I would have changed:None What others should know:When replacing the seal I filed all the burs on the receiver (tube) on all machined areas. This helped when installing the seal so the sharp edges didn't cut the seal edges. Anyway just something that seem to help in the installation.
