Just ordered my US Optics 5X25, then found out the ridiculously expensive scope base for picatinny rails on my McMillan stock is on back order or "unavailable". Need some opinions for best 20MOA base for 34mm tube. Yes, Leupold is available, but is it worth the money? Sold my M1-A and Nikon optics, and got custom rifle, but customizing is a PITA! Looking forward to going back to scope had the opportunity to play with when was with Uncle Sam if I can get it mounted on the rifle!!!!
