Few guys local wanted to build these so I asked Dave Manson to make me the reamer... (BEAUTIFUL WORKMANSHIP!!!)
Long story short... we are going to make a dozen or so barrels... Remington 700 (.223 boltface) and AR-15.
This is a pre-sale if you want a barrel (i.e. I am having my Smith make barrels this month and if you want one we will add you to the list).
Cost $250 shipped for R-700 and $270 shipped for an AR-15 barrel ($20 Del-Ton barrel extension).

FYI, I bought the reamer with .357 and .358 live pilots, so your choice.

More reading here... this guy has built a few and hunts with them... he seems like he is very smart.
