Rebarreling is expensive. A replacement factory barrel is £684.99 inc VAT, takes and estimated 10-12 weeks from order to delivery, and would require UK proof after fitting. Aternatively, you can get the job done by Steyr, which costs just £650.00 including fitting and proofing... Sounds good, except that as of January 2021 the charges for its round trip to Austria will put another £350.00-£450.00 on the cost. This leaves getting a more universal replacement barrel fitted by a UK riflesmith, the awkward thing here being that the breech end for the new tube has to be mated to the breech extension containing the locking lugs, and that makes it quite a specialist job. It really ought to make sense to rebarrel, but by the time you've factored in all the time, cost and effort, there's little incentive not to start again with a new rifle.
