They made probably thousands of target rifles out of No4s with the same barrels as the L42, so there'd be nothing difficult about that job for them.

The opening out of the barrel channels on such target rifles could be rather rough from my limited observation as it was done by hand, but anyone who wants better just needs to set the forend up in a milling machine or duplicator etc. and rout out the channel with a round nose cutter.
