New Contiuum barrel?

All the SUPERLITE components interchange, the other day I got the .22 500mm & 600mm HEAVY SUPERIOR liners and like you only had the 700mm CONTINUUM, I simply took the shrouds I had in those lengths and fitted them to the .22 set-up!

However it is very easy to shorten the longer shroud, the liner actually floats in it, there is no location at the inner end, hence the length you end up with is not critical.
