I just received my new BASSET mount today(HIGH) . I do not regret my purchase directly from BASSETMACHINE (10 days only to arrive in France)
It is a solid piece and well finished, I intend to use it as soon as I receive my new LEUPOLD VXIII ordered also at RIFLESCOPESTORE (thanks the U.S.A)
The SA Gen 4 mount is not bad. It's another copy of the Brookfield mount and available in steel as well as aluminum. It's not a bad lower cost alternative, but doesn't measure up to the quality of Sadlak or even SEI. I like the open rail design which reduces the chance of brass hitting the mount and bouncing back into the action. Early ARMS mounts did this as well as Unertl, who never got theirs into production. I have examples of the Unertl prototypes in both standard and long rail lengths. Wish they would have followed through.
