Carlson's Flush Mount Replacement Improved Cylinder Choke Tube for 12 ga Mossberg .835/.935 .760

The Carlson's Flush Mount Replacement Improved Cylinder Choke Tube for 12 ga Mossberg .835/.935 .760 is a precision-engineered choke system designed for tactical and hunting applications where shot pattern control directly impacts field performance. This flush-mount design eliminates external protrusions, reducing snag points in vehicle storage, tactical vests, and close-quarters engagements while maintaining full bore diameter optimization. Law enforcement and military operators who rely on Mossberg Ulti-Mag shotguns for breach and entry, riot control, or wildlife management demand choke tubes that integrate seamlessly without compromising handling speed or safety margins.

Built from 17-4 heat-treated stainless steel, this improved cylinder choke delivers superior corrosion resistance and dimensional stability across extended firing cycles and harsh environmental conditions. The 17-4 metallurgical composition provides hardness retention after heat treatment, resisting deformation from sustained pressure cycles and thermal stress inherent to modern shotgun use. The improved cylinder constriction pattern opens shot clusters faster than tighter chokes, ideal for dynamic scenarios requiring rapid target acquisition at intermediate distances. This tube accepts both lead and steel shot, offering operational flexibility—though Carlson's recommends steel shot exclusion with turkey-specific variants to prevent erosion.

Installation is tool-free on Mossberg Model 835 and 935 Ulti-Mag shotguns equipped with interchangeable choke systems; simply hand-rotate the tube into the receiver's flush-mount socket until seated. The .760 bore diameter specification ensures tight machining tolerances that prevent gas leakage while maintaining consistent shot velocity and pattern density. Operators running 3.5-inch magnum loads or specialty ammunition (buckshot, slugs, or non-lethal rounds) will appreciate the robust 17-4 construction's ability to withstand pressure spikes without dimensional walk or premature wear. Verify chamber length and choke system compatibility before installation; this tube is exclusive to 12-gauge Ulti-Mag receivers and incompatible with standard Mossberg 500 or 590 platforms.
