I've used mostly Talley aluminum lwt's for the last 8+ years... never a problem and have had close to 2 dozen on a variety of rifles.

My favorite ring/base combo, hands-down. In fact, just ordered another set for an M70 this afternoon...

Can't see gumping-up a rifle with anything else unless you happen to want a QR ring, or want a little lower mounting than the Talley Lwt's give...
