A replica of a grenade cup discharger used by British army during ww1 and ww2. This is a fully functional model:

• the whole thing can be mounted on your real or replica SMLE rifle,
• the setscrew can be adjusted for a tight gas seal,
• the gas valve (and thus the range) can be ajusted with a threaded knob.Great for reenactment and display.

This model is fully compartible with my №36M Mills bomb model:https://www.cgtrader.com/3d-print-models/miniatures/memorabilia/no-36m-grenade-mills-bomb

For a proper assembly you will need:

• two 30mm long and 5mm diameter round pins,
• a m5 standart nut,
• a m5x16 or m5x18 screw

Warning!It is strictly unrecommended to fire any live ammo through the thing. It will most defenitely blow up and may injure you.
