Product Description
MG34 Booster Cone For Blank Firing.
Includes:
• Cone Threaded 7/16-20.
• Three Restrictor Screws:
- 1/8" through hole: This is for more powerful blanks.
- 1/16" though hole: This setups worked well with British L13A1 blanks. Austrian blanks are too weak to cycle with this aperture, a smaller aperture would be necessary.
