Browning 1133283 Invector-DS Browning 12 Gauge Improved Cylinder Flush Stainless Steel Chrome

Browning’s Invector-DS choke tube features a double seal design that maintains cleaner tubes throughout use. The extended choke taper is engineered to optimized percentages rather than dimension alone. This choke sits flush with the barrel end while offering greater length than competing tubes. A proprietary differential banded gas seal prevents residue accumulation and simplifies removal and installation. The integrated spring suspension maintains seal pressure while accommodating expansion and regulating gas flow. Invector-DS tubes are compatible only with Browning shotguns designated for Invector-DS and cannot be used in shotguns marked Invector-Plus or Standard Invector on the barrel.
