TECHNICHOKE® interchangeable choke model SPORTING XP70. Available in 12, 16, 20, 28 and 410 calibres, in various sizes to be used depending on the different types of situations that hunters encounter during the hunting season, while for shooters it is increasingly becoming an essential requirement. TECHNICHOKE® interchangeable chokes, model SPORTING XP70, are made of raw alloy steel with R85-100 resistance. Internal and external nickel plating treatment gives the TC choke high resistance to salt spray. In addition to increasing corrosion resistance, this treatment makes the choke particularly shiny, gives it uniform colour and increases its surface hardness (500/550) HV. The F.A.I.R.® TECHNICHOKE® choke is also suitable for steel shot (depending on calibre and size) and the internal geometry has been specifically designed for better shot passage, better penetration and less friction on the walls. The TECHNICHOKE® choke is carefully checked on the production line during manufacture. Each choke is supplied in a blue plastic container. Length of the SPORTING XP70 choke: approx. 70 mm. External extension approx. 20 mm.

We strongly recommend that a choke of no greater constriction than Modified (***) be used when firing steel shots.
For example, using an Improved Modified (**) or Full (*) choke when firing steel shots may cause damage to the barrel and void your warranty.
CWe always recommend that you carefully read the instructions on our “owner’s manual” and ammunition box just for more detailed information.
