The TRUGLO Titan is the only choke you need! The only choke that lets you adjust it quickly, and without tools from Cylinder to XX Full, the Titan is the one choke you need for just about everything. Adjustments range from Cylinder up to XX Full constriction, and are laser marked, for quick sure adjustment. A smooth black finish keeps water from collecting, and keeps operations smooth. Ported design also reduces recoil and allows for quicker follow up shots.
