let me know how that shoots...
I can get a .44 mag or .357 mag barrel for my NEF gun, and have been considering shipping it off.
I'm sure you know this, but for everyone else, there's 2 models of stocks that allow you to get different barrels for in this line, one that is a rifle, and one that is a shotgun.
the rifle can accept most common rifle calibers and most common shotgun gauges.
the shotgun can accept most common shotgun gauges, and the "mag" pistol calibers.
you just pull your barrel and send the rest of it by mail and they fit the barrel and send it back to you.
great guns.
cheap and pretty reliable.
I've put TONS of rounds through mine, and I know of a few others that have had tons too.
