Ống Trên Cho Airsoft B&T MP5K

Top tubes for the B&T MP5K with a separate cocking tube piece. Replaces the original part and gives more battery space.
One with rail and one without.

Other than that exactly the same models.

Reinforced at the two points where it attaches to the receiver. The screw and the upper back pin.

It's designed to have an 11mm to 14mm adapter melted into the front, but you could probably also cut a thread for it.

Fits original MP5K handguard, but might not fit aftermarket handguards without some modifications, so the step file is included.
