I do not know how the future will pan out for mil shooters as the cache of original barrels starts to dry up its not panic buying its just the stocks are running out and those that have the gear are keeping them for the future. I have enough for my son who is 14 y/o to continue for his shooting career but a lot of years in the making. I managed 10 years ago to get a complete Mk III standard profile barrel but they are pretty scarce now. It has been an epic and endless hours trolling sites and getting into trouble not having a 709B form for that barrel that was a close squeek but all was good in the end. So I really do not know what the future holds for the 303 's or the K-98's etc as we are just going to have to go with non genuine parts to continue having our fun.
I saw an unfired Mk III H barrel $450.00AU and one with 50 rounds through it H Mk III for $300.00 and the prices of stocks and ancillary parts has skyrocketed I am so glad I started a while ago hedging though the woods are the issue if you want genuine and have a full wallet.......
Keep the faith and enjoy milsurps as I sure am......
