This post will be a guage of interest in replacement barrels for the Tavor.
I have talked to Jon about barrel pricing, lengths, availability and who is allowed to install them. Here is his answers.
Price: approximately $450-$500 subject to change (was a guestemation by Jon)
Lengths: both NR and CTAR could be made available.
Availability: IWI would need a run of at least 100 barrels for it to be worth while for IWI and North Sylva. NS also doesn't want their money tied up in inventory. Jon said he thinks replacement barrels will probably come some time next year.
Who can change the barrels: NR barrels can be changed by you or Jon. CTAR barrels must be installed by Jon to insure that the rifle gets properly registered.
