Hi,
I just want to express a big thankyou and say how impressed I am with Gmac's service.

I placed an order for about 12 spare parts for my 1377 and my 2250b at around 2am yesterday morning. I got a confirmation email at just after 9 the same morning and all my bits were here this morning.
I would recommend them to any UK Crosman owner.
