This HPA adapter turns the GBB STEN into a far more skirmishable weapon. Use in conjunction with straight or short CYMA MP5 magazines.
Requires feed lips from a donor GBB STEN magazine. Valves are all pre-fitted for your convenience.
Requires sanding down of a small notch inside the feed lips. Trivial, happy to do for you / demonstrate if required :)
Do not run high PSI with this adapter. Our adapter will not explode, your gun will! Keep it < 120psi
