I am doing a 1 off large caliber ar15, and am having a hard time finding someone to build me a barrel.

Any links would be appreciated.

It would be helpful to know which caliber barrel you're looking to have made, then someone might be able to let you know if what you want is feasible or possible.

375 based on a Beo case. Basing it on a beo case due to the rim size and I already have a beowulf. Sort of like a 458 socom or a beowulf with better ballistics and deeper fpe in the 250-300 grain area.

I have already dicussed it with Dave Kiff at pacific tool and there is no problem with a reamer and a go gage, and RCBS and I came up with an easy fairly reasonable soluiton for the dies.

I have a lathe and have reamed a few bolt action barrels, but tooling up to make an AR 15 barrel is something I would rather pay someone else to do since I have never done one before.

I think I might have found one guy that can do it. Basically just need to start with a Shilen or douglass 375 blank.

If I can get this one round to work out maybe one of these days I might get around to a looking at a 375 jurras ar15, but the brass work would be major as you would have to turn a rebated rim on 475 nitro brass and they cost around $3-4 each.

Check here. I hear this guy does good work. Maybe he can help.
