Minimum gap geometry and high resolution RMS interior
finishes gives less pellet deformation; consistently tighter patterns. Perfect
for shooters who need the original spectrum choke, but with the sharp black
oxidized finish. Choke constriction is laser marked, on color-coded band so
there is no need to remove choke to verify size. Long tube with hidden wrench
slots extends beyond the length of the muzzle. Knurled grasping band speeds
installation and removal.
