Outer Barrel Movement

[Baz JJ]

I own two GBB pistols and when cleaning and lubricating them, Ive noticed that the outer barrel on both has about 5-10mm of fore and back movement when the slide operates. They are different makes and model of gun and quite new/never been skirmished.

Are they designed to do this ?

the outer barrel is pretty much floating so will wobble a fair amount. It is annoying but seems normal to me (have had 4 GBB pistols that all do it)

Yes this is normal, don't worry about it

Does anybody know why it does this?

because it is a moving part. It is designed to move else when the gun cocks it would jam
