These Competition chokes can be used on all Mobilchoke barrels. Made of high quality steel, they are of a great stress resistance due to heat treatments. They are subjected to a special coating that guarantees high protection to corrosion. They are extended by 25mm-0.98” and their external shape has been studied in order to guarantee installation and de-installation without specific tools. The end of the choke is identified by a colored alloy stripe for fast and easy indication of the constriction.  These chokes are for 20 GAuge shotguns only. 

We suggest that - when using Steel Shot - you only use choke tubes marked with the SP (Steel Proof) identification on the side and that you use the most open choke system possible – i.e. Cylinder / Improved Cylinder / or Modified.  We DO NOT recommend use of Steel Shot in the X-Tra Full Turkey / Full / or Improved Modified choke tube. As with any shotgun, always be sure to check your choke tubes during use to verify that they are tight in the barrel. Loose choke tubes can cause barrel damage.
