Long shotgun choke tube extends beyond the length of the
muzzle, features highly polished interior for less pellet deformation; reduced
fliers and tighter patterns. Knurled grasping band speeds installation and
removal. Porting reduces felt recoil by 5%. Shotgun choke constriction is marked
on band so there is no need to remove choke to verify size. Helical rifled
Diffusion spreader tubes provide a pattern that is more open than
cylinder.
It is not recommended
to shoot Federal's Black Cloud or any of their ammunition that utilizes their
Flight Control Wad in ported chokes due to interference with its
performance.
Please note, this choke does not fit Franchi Aspire, Benelli Montefeltro, or the Beretta A400
