5KU lantac razorback RMR cut slide

9ine outer barrel + inner barrel and hop 

Enhanced recoil rod and spring

Guns modify zero Blowback unit with..

Laylax piston head rubber

Doesn't play well with my hammer unit and too many projects to get this working

The blowback unit is installed, but the retaining screw has become fairly rounded so a star shaped screwdriver is needed for removal possibly a T8?

Sold for spares

Nothing is broken and everything is new as it's just been installed and racked and attempted to get working quickly, but lack time to put into this project 

Doesn't work with the hammer unit I have and it's up to you to get this working with yours so this will be F&F payment only
