The laser-etched gold accent band on Browning's exceptional 12 gauge Midas Grade Invector-Plus Extended choke tubes is a sign of top performance. It extends beyond the end of the barrel for easy removal and installation. It features a stainless steel construction with black oxide finish and laser-etched godl accent band. Minimum gap geometry plus high-resolution RMS finish reduces plastic buildup in the bore. It is available in constrictions from Spreader to X-Full. This choke tube only fits 12 gauge Invector-Plus choke systems. Flat choke tube wrenches are not compatible with Midas Grade Extended choke tubes.
