I've been ripping cans up in the garden with my Swiss Arms Uzi today. (I bought 100 CO2 carts for just £32 posted. Thanks Ramsbottoms)
I've been shooting my other BB replicas a lot recently, and getting this out today made me realise how much I enjoy shooting it.

The problem is its just so plasticky! The mag is full of lead to give the impression of solidness, but in reality its a metal frame wrapped in black plastic with nasty black plastic grips.

I have seen the Guarder Aluminium receiver sets on t'interweb and wondered if anyone here has seen, fitted or bought one? Also, is there a steel barrel relacement for .177? If not I will probably machine my own.
Lastly, are the grips compatible with real ones, if so, has anyone found a decent set?

I'm gonna pimp ma Uzi!
