Cost to manufacture WWII weapons

[Peter Laidler]

I realise exactly what you were referring to Beery. Just making the point that you CAN use a ported barrel - as has been done on several occasions - just so long as it is deemed irreversible. The SA80 single shot target LSW's had a ported barrel BUT an unported gas block and no facility for gas. I know, because I owned one and queried it on the basis of earlier 'sort-of related' case law. My friend has a suitable machined down and sleeved 7.62mm Bren barrel on his No5.

BUT, I wonder how you'd go about using a Vickers MMG barrel suitably machined in a rifle in the UK............

Understand, I'm not stirring here...just trying to grasp. That's why I was wondering about a spot weld over a gas port. At one point I was able to de-register an M1 carbine when I changed it to a pump rifle...did two of them actually. That time is past. They've changed all that here. Doesn't matter, we can only use a 5 rd mag on that sort of thing. Takes the fun out of it.
