Put a Sportsmatch Dampa mount on it and any scope will last longer. On my R1 I have a $100 Hawke 3-9x40 Vantage mounted in a Dampa mount with no problems. That scope is only rated for 12 fpe and my R1 is making 19. My other choice is an Hawke Airmax. DVOR just had the 4-12x40 Airmax on sale for $148. That's a killer deal. It might still be available. I'd still put a Dampa mount under it if you can afford it. Typically I go with the Airmax on big springers. The Dampa mount gives you more options because it absorbs a lot of the recoil. My Rx1 had a Dampa mount and 4-12x40 Airmax with zero problems.Good luck Ron
