Starik Carbon Tube [STAR-TUBE]

From: £274.00


A extraordinary barrel tube, which features:

  • Long sighting distance for more accurate aiming.
  • A built in tuning weight which is used to tune the rifle for "positive compensation"
  • A short collar of only 25mm in length clamped on the rifle barrel which ensures the choke is at the muzzle.
  • Every tube is custom made to each barrel length and diameter using a calculation of odd harmonics to tune the rifle for best groups and decimal score (every tube will be different in length, depending on the barrel length).
  • The tube is made from a combination of carbon and aluminium, making it about 200g, which makes it comfortable to use for both 3p and prone shooters.
  • Two lengths of the tube are available:
    • The short tube is about 18.5cm +/- 1cm
    • The long tube is about 31cm +/- 1.5cm
  • An indexing ring in order to connect the tube at the exact position on the barrel.
  • The tube can be made in any barrel diameter requested by the customer.
In order to produce the perfect tube for your barrel, two measurements are required: Exact barrel diameter at the muzzle, and exact barrel length.

To determine your exact barrel measurements please follow the following procedure:

  • Make sure your rifle is safe.
  • Insert an empty shell to the chamber and close the bolt.
  • Insert a cleaning rod from the muzzle end until it stops.
  • Mark the rod right at the muzzle.
  • Take the rod out and measure it from the end till the mark.
  • That's your exact barrel length.  If you don't see this option in the drop-down box above, please select 'Other' and then put your measurement in the Comments box when you checkout.

Measure your barrel diameter at the muzzle with a digital calliper.

    I've never tried an extender so it was with trepidation that I bought this one. Fitting it was dead easy with a small spirit level and holds zero every time I shoot! Reduces muzzle flip and helps me maintain my hold. Great bit of kit!

    Follow the instructions and the fitting is quite simple - not had a full chance to test it yet but initial results are good.
