I have a Palmetto State Armory AR10 308 Win. I recently purchased a Nikon Buckmaster II scope. Now I need a good quality solid ring mount in the $250.-$300. range new or used. can anyone direct me to a quality ring mount. I'm willing to go a little more if needed. I like the Spuhr mount and new it ranges from $410.-$450. I spoke to their rep this morning and they don't have one for a 1" or 25.4 MM tube. Any help would be appreciated.
