BKL-303 30mm Single Strap 9-11mm Dovetail Rifle Scope Mount Rings - Medium - Silver
Rock-solid 30mm scope mounts for air rifle or rimfire
Self-aligning clamping, scope-friendly rings, and no-lap installation
For 9–11mm rails. Precision fit – Easy setup – Scope tube protection
32mm base to ring center. Scopes upto 60mm objective outer diameter on flat base.
Don’t rely on the word “Low.” In BKL’s lineup the 303 is lower than their 300/301, but compared to most brands it’s closer to a Medium. There’s no industry-wide standard for ring height, so always go by the actual measurement: 17 mm base to ring bottom / 32 mm to centre.
BKL’s precision-engineered 303 rings are designed for 30 mm scope tubes and rifles with standard 9–11 mm dovetail rails.
With their single-strap, two-screw design, these mounts deliver a secure and perfectly aligned hold without unnecessary bulk.
The low profile makes them ideal for keeping optics close to the bore, helping maintain a natural cheek weld while still providing clearance for smaller to mid-size objective lenses.
CNC-machined from high-grade aluminium and finished in a sleek silver anodising, they combine durability with a smart look that pairs beautifully with stainless or silvered rifles and scopes.
Lightweight yet tough, they’re simple to install and hold zero reliably on airguns and rimfires.
Perfect for:
-
Airgun and rimfire rifles with 9–11 mm dovetail rails
-
Shooters who want a clean silver finish to match stainless rifles or optics
-
Scopes with 30 mm tubes and smaller/mid objectives that benefit from a low mount
- Specifically scopes with objectives upto 44mm. May suit 50mm scopes but only models that do not have an AO Adjustable Objective. AOs will be too big
Scope Clearance Guide (example):See FAQs for more info
Distance base to ring center = 32mm. Ring diameter = 15mm
- Scope measured with outer diameter (no lens) 60mm bell = 30mm radius
- 30 – 15 = 15mm needed under bell
- Mount offers 17mm → ~2mm clearance
(Add ~1mm safety margin to your calculation)

BKL 303 30mm 2 pc single strap low dovetail scope rings SILVER.
Q: Will these fit a Picatinny or Weaver rail?
A: No—these are designed only for 9–11 mm dovetail rails.
Q: What size scopes will they fit?
A: Any scope with a 30 mm body tube, ideally with smaller or medium-sized objectives.
Q: Why choose low mounts?
A: Low mounts keep the scope closer to the bore for a more natural cheek weld and reduced holdover at close ranges.
Q: Are they strong enough for recoiling rifles?
A: Yes—machined aluminium with a secure 2-screw design provides solid strength for airguns and rimfires.
About silver mounts and accessories:
While black is the most common finish for rifle scopes and mounts, silver or bright anodised finishes are popular for pairing with stainless steel, nickel-plated, or silver-coated rifles and scopes. They provide a smart, coordinated look without sacrificing strength or durability.
Q: Why choose silver mounts over black?
A: To match stainless or silver-finished rifles and scopes for a clean, professional appearance.
Q: Is the finish as tough as black anodising?
A: Yes—silver anodising is just as durable and scratch-resistant.
Q: Does the finish reflect more light?
A: Not noticeably—the surface is usually satin or matte, minimising glare.
Q: Are silver mounts rarer?
A: Yes—most mounts are black, so silver is often chosen for a custom or premium look.
Q: I’m unsure if they’ll fit my setup — what should I do?
A: Measure your rail width and objective diameter, then compare with the clearance guide below. If still unsure, contact us before buying.
Step 1 — Measurements to know
-
Base → ring bottom: 17 mm
-
Base → ring centre: 32 mm
-
Scope objective diameter (e.g., 60 mm)
-
Rifle: distance from top of dovetail to barrel/receiver
Step 2 — Quick calculation
-
60 mm objective = 30 mm radius
-
30 mm tube radius = 15 mm
-
Clearance needed under bell = 15 mm
-
Mount provides 17 mm → ≈ 2 mm spare clearance
Step 3 — Safety margin
Add 1–2 mm extra as buffer. If you’re running a fat objective, barrel shroud, or close-fitting action, consider the taller 300/301 models.
