Carlson's Choke Tubes 09220 Bismuth Bone Buster Browning Invector-Plus 20 Gauge Mid-Range 17-4 Stainless Steel

The Carlson's Choke Tubes 09220 Bismuth Bone Buster is a mid-range choke tube built for 20-gauge shooters who want reliable, patterned performance without breaking the bank on premium ammunition. Designed specifically for Browning Invector-Plus shotguns, this choke is engineered from 17-4 stainless steel—a material choice that delivers durability and corrosion resistance in the field, whether you're hunting upland game or working clay targets. The Bismuth Bone Buster name reflects its tuning for bismuth shot, a non-toxic alternative that patterns differently than lead, and this choke is optimized to deliver consistent results with that load profile.

If you shoot a Browning Invector-Plus 20-gauge and want a straightforward, effective choke that handles mid-range distances, this tube bridges the gap between budget options and high-end competition chokes. Stainless steel construction means it'll stand up to repeated use and seasonal storage without pitting or degradation. For hunters and sport shooters alike, a good mid-range choke is the workhorse of the gun rack—it covers most practical hunting scenarios and gives you the flexibility to focus on gun mounting and shot placement rather than guessing your pattern.

Carlson's builds these tubes to Invector-Plus specifications, so fitment is straightforward if your Browning shotgun accepts that system. Whether you're assembling a versatile choke set or replacing a worn tube, the Bismuth Bone Buster gives you a proven option backed by real field use across North America.
