   How did you connect the bottle onto the main tube?
I bought a similar tank for CO2 project using a dropblock, but this might have changed my mind.

	Hope this shows it ok. I used some high pressure gas fittings. 1/4inch copper pipe from memory with 1/8 bsp threads.

	I made a dummy canister inside with the 1/8bsp out the side, routed back to a paintball adaptor that was modified to fit into the back of the tube behind the valve and hammer. The suppressor was off my Cr600 Edited by Billbobnz - 11 Sep 2025 at 11:37pm

	Great stuff. Did the cheek height work out well using the red dot?
