Have four sets of TPS rings and will soon have five. They are good as anything else out there. I have a set of Badger rings and while the TSR rings are dimensionally smaller in all aspects the machine work and finish of them is outstanding. Pictures really don't do them justice.
I have one of their bases and same as above. I will note that it had be be bedded to my action since there was a bit of gap between the rear of the base and receiver. It is installed on Remington a 700 wich are known to have variations in the milling of the rear portion. I didn't have that problem with my Badger base or the EGW bases I have on other rifles, but I didn't try a different base on said rifle. It was probably the gun, I just can't say for sure.
They are not just great rings and bases "for the money" they are great rings and bases and you can't go wrong with them.
