The RPM Precision 30mm Medium (1.00") Scope Rings with Co-Linear Bubble Level provide a clean, purpose-built mounting solution for 30mm riflescopes. Machined from 6061-T6 aluminum with a stainless steel cross bolt, these rings integrate a co-linear bubble level directly into the rear ring so the shooter can verify rifle cant without adding extra accessories or clutter to the rifle.

This medium-height ring set is well suited for precision rifles and serious range use where consistent leveling matters for repeatable hits. The integrated level helps during initial scope installation and every shot thereafter, making it a practical choice for long-range practice, competition, and general training. Rubicon Precision Manufacturing’s attention to detail and thoughtful design are evident in the alignment lug, smooth machining, and solid lockup.
