What bases are you using? Im assuming they are 2 piece steel bases?
What size objective.....I can tell you for sure that Warnes bases and Warnes low 1" rings WONT fit a 42mm objective on my Mountaineer or Super DISC.
Weaver Grand Slam or older Loopie steel bases with 30mm ring might but it will be super close. Those 2 bases are a very tiny bit taller than the Warnes steel bases.
Bound to see lots more “sintered steel” (if even disclosed) with the proliferation of 3d printers! I don’t know how Leupold makes their QRW’s, but I’ve got more than one pair and think they’re well made.
