You'd likely be happy with something from any of the people who make .17 barrels. I have .17cal. barrels by Douglas, PacNor, Wilson match, Shilen, and Montana Rifleman. They all shoot very well and I'd recommend any of them. There's a Lilja barrelled gun that hasn't been fired yet and a couple Pence barrels waiting to be chambered.....those two brands are supposed to be excellent also. The choice might boil down to what's available without too much of a wait. Lilja used to keep Rem. varmint contour .17 barrels in stock, you might give them a call.
