hi, it is set up like a savage with the barrel nut but threaded for a remington 700.
the barrels are threaded ,chambered and crowned. you would need a barrel wrench and headspace gauges to install them. it also saves you money by not needing a gunsmith.
barrel blank $350
criterion ready to install $350
of course you need the tools but thats a one time cost made sense to me.
the tools i have will work on savage or remington
thanks for looking
