Choke Design

Chokes - Three finishesSupported by more than 20 years of research into shotgun ballistic dynamics and tight tolerance computer (CNC) machining, Comp-n-Choke choke tubes deliver more precise, denser patterns to your target.

The Choke design allows gases to vent through slots, generating a brake system, which reduces recoil and gives quick recovery for the second shot.  The slots also slow the wad, allowing the shot column to exit the choke clearly ahead of the wad.  This eliminates flyers (when the wad drives through the shot column) delivering a more dense pattern.  The more dense pattern allows you to use a more open constriction, providing a larger pattern and improving your performance.

Comp-n-Choke tubes are computer (CNC) machined for precise tolerances with high quality steel.  The extended portion of the tubes offer a conical parallel design, with the final constriction of the choke held roughly 1 1/8 inches.  Chokes are roll marked for quick identification.  Then extend design allows easy field installation and quick changes.

Chokes for most popular guns are stocked in a variety of finishes: black, stainless or gold titanium.  Custom sizes are available on request.  Contact us at sales@comp-n-choke.com for assistance.

Standard Bore Diameter:

Delivering a precise, consistent pattern requires precision manufacturing.  Most shotgun makers produce barrels with a standard bore diameter.  We stock choke tubes for shotguns with the standard bore diameter listed below.  If you have backbored your gun, or the bore diameter is not this standard for some other reason, please contact us for custom-size choke tubes.

Patterning Tips:

  • The only way to know your gun's performance is to pattern it with the chokes and shells you intend to use in the field or for Clays.
  • Too much of a constriction in a choke tube is just as bad as not enough constriction.
  • Use a good rest.
  • Use a large sheet of paper, at least 36 inches, to show exact pattern concentration.
  • Shoot at least two target - each with different type loads and brand of shells.
