Carlsons Bone Buster Bismuth 12 Gauge Medium Range Waterfowl Choke — Extended Non‑Ported, Benelli Crio Plus

Carlsons Bone Buster Bismuth Medium Range choke is engineered for waterfowlers who use non‑toxic bismuth and need tight, consistent patterns at medium distances. The extended, non‑ported design and Benelli Crio Plus thread compatibility deliver dependable patterns, reduced fouling, and easy installation so you can focus on the shot.

Product description
This extended non‑ported choke is specifically profiled to maximize pattern density with bismuth shot while remaining safe and durable for repeated use. CNC‑machined from high‑strength stainless steel with a corrosion‑resistant finish, the Bone Buster delivers predictable, uniform pellets at 30–45 yards (medium range) and resists wear from non‑toxic shot. The extended length improves shot column formation and makes it easier to remove and install in the field.

Key features and benefits

• Medium‑range patterning optimized for bismuth shot for tighter groups and consistent pellet distribution at typical waterfowl distances.

• Extended, non‑ported profile promotes a clean shot column and reduces felt recoil and blast at the shooter's face and ears.

• Benelli Crio Plus thread compatibility ensures a precise fit and safe interchange with Benelli Crio‑style barrels.

• Durable stainless steel construction with corrosion‑resistant coating for long service life in wet, salty field conditions.

• Precision choke bore profiling and smooth internal finish reduce pellet deformation and minimize fouling.

• Easy hand or tool removal thanks to extended length and knurled exterior for positive grip even when wet or gloved.

• Designed for use with bismuth and other approved non‑toxic shot; safe for most modern barrels when used per manufacturer guidance.

• Ideal for waterfowl hunters seeking improved downrange lethality with non‑toxic payloads at medium ranges.

Usage and installation instructions

1. Verify your barrel uses Benelli Crio Plus (Crio) threads — check barrel stamping or manufacturer documentation.

2. Unload the shotgun and follow all firearm safety procedures before touching choke tubes.

3. Clean the barrel face and choke tube threads to remove debris.

4. Hand‑thread the choke into the barrel until snug; use the supplied or appropriate wrench for final snug fit per manufacturer torque guidance. Do not over‑torque.

5. Test patterning with the loads you intend to use (preferably with shot capsules or paper patterning) to confirm point of impact and pattern density at your typical hunting distances.

6. After use in wet or salty environments, remove the choke, clean threads, apply a light film of choke lube, and reinstall or store dry.

Compatibility and safety notes

• Confirm Benelli Crio Plus thread compatibility before purchase; incorrect thread fit can damage barrel or choke.

• Use only approved non‑toxic shot types specified by your jurisdiction and shotgun manufacturer.

• Always pattern the choke with the loads you plan to hunt with to verify performance and avoid unsafe point‑of‑impact shifts.

• When in doubt, consult your shotgun manufacturer or a qualified gunsmith prior to installation.
