The CARL BER/BEN MOBIL 12GA Rifled Choke Tube brings precision rifling to your shotgun's smooth bore barrel, giving you measurably tighter shot groupings when you need them most. Built from 304 stainless steel and finished in matte black, this choke tube is engineered for shooters who demand accuracy—whether you're working buckshot patterns at the range, patterning slugs for deer season, or fine-tuning your shotgun's performance for competition. The rifled design features a right-hand twist of 1-in-35, which stabilizes projectiles as they exit the barrel for improved consistency downrange.
This tube protrudes between .625 and 1.3 inches from the barrel depending on your specific shotgun platform, and the .730-inch groove diameter is optimized for 12-gauge loads. The 304 stainless construction stands up to repeated use and corrosive primers without degrading, so you won't be chasing accuracy issues caused by worn or corroded internals. If you've been frustrated with loose patterns or inconsistent groupings from a smooth bore, a quality rifled choke is one of the simplest upgrades available.
Installation is straightforward on any shotgun that accepts standard choke tubes—just thread it in and get to the range. The matte finish resists glare and blends with most barrel finishes. Whether you're a slug hunter, competitive shooter, or someone who just wants to know exactly where your gun is shooting, this tube transforms how your shotgun performs.
| Gauge | 12GA |
| Material | 304 Stainless Steel |
| Finish | Matte Black |
| Rifling Twist | 1-in-35 (Right-Hand) |
| Groove Diameter | .730 inches |
| Protrusion | .625 to 1.3 inches (varies by firearm) |
This tube threads into any shotgun that accepts standard 12-gauge choke tubes. Protrusion depth varies between .625 and 1.3 inches depending on your specific shotgun platform, so fit will depend on your barrel's design. If you're unsure whether your gun uses removable choke tubes, check your owner's manual or the barrel marking.
Yes. The 1-in-35 right-hand rifling stabilizes projectiles as they travel down the barrel, which translates to tighter, more consistent shot groupings compared to a smooth bore. This is especially noticeable with slugs and sabot rounds, though it benefits any shotgun load.
The 304 stainless steel construction is engineered to withstand repeated use and resist corrosion from primer residue and environmental exposure. The matte black finish provides additional protection and reduces glare.
Standard choke tubes control pellet spread through constriction alone. This rifled tube adds stabilizing rifling to improve accuracy by putting spin on the projectile, resulting in better downrange performance and grouping consistency.
