Bleeder NFRC

I made this 16mm to 16mm Nerf barrel coupler with porting to make a way to quickly reduce FPS on any protruding barrel Nerf blaster.

It works by bleeding off the back pressure but then you still have an additional length of barrel to add friction to the dart and slow it down.

I used this to lower my Zius BK2S from 160 FPS to 130 FPS with no loss of accuracy or inconsistency.

I am using 15cm of aluminium barrel to go from 160 > 130

I also tested 25cm of barrel to go from 160 > 110

There is a ridge inside so print with supports on the bed.
