Warne quality is a little on the low side. Deffinatly lap warne rings. I bought one pair, they were difficult to lap by the design. They didn't stay on that rifle long and were replaced. They were their TPA ring.(tactical permanent attach)
I would recomend Leoupold PRW rings, if your looking for low cost. They mount easier, but should still be lapped for full contact.
Brownells carries a Tactical Percision HRT and TSR rings. The price looks good but I can't comment on the quallity.
I ordered 2 Warne 20moa bases and was disapointed with the quality. The edges were rough and had a machining burr along there length. This wouldn't allow the base to full contact into the rings dovetail. It kind of rode on that thin turned over burr. I corrected it with a diamond stone and fine file. There finish is not very durable, maybe as good as 99 cent spray paint. When I was done I did have a usable base.
