Scope Rings & Mounts
The clamping rings that hold your scope to the rifle. The piece of metal between accuracy and frustration — get it wrong and your scope walks every shot.
The quick answer
Scope rings (also called scope mounts) are the metal clamps that hold your scope to the top of your rifle. They’re the most overlooked accuracy upgrade on a PCP setup — the scope is precise, the rifle is precise, but if the rings are wrong size, mounted crooked, or come loose, your shots will walk every magazine.
The two decisions you have to make are what rail pattern is on your rifle (11mm dovetail or 20mm Picatinny) and what tube diameter is on your scope (1-inch, 30mm, or 34mm). Get both right and any of the rings below will work.
When shopping
What to look for in a scope rings & mounts.
- ✓Match the rail pattern: 11mm dovetail OR 20mm Picatinny This is the first decision. 11mm dovetail is the old standard — found on older Stormriders, PR900 originals, most Diana/Artemis rifles, Beemans. 20mm Picatinny/Weaver is the modern standard — found on the Snowpeak Lynx Gen 3, modern Avengers, JTS Airacuda, and most rifles built after 2020. Check your rifle's rail before you order rings. If you're not sure, look at the rail's cross-section: dovetail flares outward at 60°; Picatinny has square notches cut across it.
- ✓Match the tube diameter: 1″ (25.4mm), 30mm, or 34mm This is your scope's tube size. 1-inch (25.4mm) is most starter scopes and budget tier. 30mm is the modern standard for serious scopes (more elevation/windage adjustment room). 34mm is for premium tactical glass like the Discovery ED-PRS. Don't try to fit a 30mm scope in 1-inch rings — you'll crush the tube.
- ✓Two-piece rings vs one-piece mounts Two-piece rings (the common pattern) clamp the scope at two points along the tube — flexible spacing, easier to fit around fat objective bells, cheaper. One-piece mounts hold both rings on a single rigid bar — better for tactical scopes that need consistent return-to-zero, especially with 34mm tubes and zero stop turrets. For a hunting PCP, two-piece is fine. For competition or PRS-style shooting, one-piece is worth the extra cost.
- ✓Ring height: low, medium, or high Determined by your scope's objective bell size and any front-sight obstruction. Low rings give the best cheek weld but require a small (24-32mm) objective. Medium works for 40-44mm objectives — the sweet spot for most PCP scopes. High rings clear 50mm+ objectives, thread protectors, or tall front sights — but they raise your line of sight off the cheek piece and feel awkward.
- ✓Bubble levels are not optional Every shot beyond 30 yards depends on the rifle being level — a 2° cant at 50 yards puts a shot 1.5 inches off target. The partner sells $15 bubble levels for 11mm, 1-inch, 30mm, and 34mm tubes. Add one to your order — they sit between or behind your rings and you check them with one glance before the trigger break.
- ✓Adjustable elevation rings for long-range work If you plan to shoot a PCP beyond 50 yards, look at the Westhunter or generic adjustable elevation rings with built-in MOA shim. They give you 20-25 MOA of extra elevation without burning through your scope's internal turret travel. Standard rings have no adjustment — what you bolt down is what you've got.
