Hey folks, got one of these: Galactic Wars Space Gun Blaster with Flashing Lights and Sounds (One Size, Grey/Blue/Black) https://www.amazon.co.uk/dp/B019OKSK7G/ref=cm_sw_r_cp_awd_8mEZwbAJJS4CG (Not from Amazon, but direct from Toyrific (still £9.99 delivered).
The front vented part looks somewhat similar to the DT-57 heavy blaster, so I thought i'd use up some of the 40mm black pipe I bought for my E-11 to build a made-up heavy blaster. I'll kinda make it up as I go along but have taken the blaster to bits to check the innards, weight it with Plasticine, etc, then drill some vent holes in the 40mm pipe.
I'll post up some pics of the butchered blaster in a bit.
