It has been mentioned a few times.,
Surpmil,s idea is good I,ve used this system on a barrel for No1 Mk V, I converted and also a No4 in .45 ACP, am Just in the process of doing the same for a heavy barrel in .22 for a No4 action, dont know what it would be like in a bigger Calibre, due to the 14 TPI, but I guess there is only one way to find out.
The Locking system on the No1 MkV below, (in .30M1 carbine shoots like a dream) but not one for the purist.....
