Recoil unit

[Martin Donnison]

Sorry guys,
another question. I have painted the barrel but now it won’t fit into delrim bushes due to the paint. What do I do

sink the delrim bush into the mantlet so the barrel can recoil.

Or leave an aluminum gap on the barrel to let it recoil without the painted barrel entering the mantlet.

Not sure what to do. Thanks Martin.

As you can see from the photo the travel total C goes into the mantlet from A to B which means if I paint up to B it won’t go into the mantlet and if I do get some very thin paint on the barrel eventually it will rub the paint away.

If I bury the bush deeper into the mantlet there will be a paint gap but that means burying the bush 7.5cm into the mantlet.

Your thoughts would be helpful.
Thanks Martin.
