Title: 4500 PSI Insert tube for qb78D
Post by: skorec on February 19, 2017, 11:48:55 AM
My Qb78/177/HPA shoot 6 pellets by use only their own air tube ( 1500-1000 PSI ).
6 shoots  is enough  for me for a weak .

To reach stable FPS I am  thinking only  insert some 4500 PSI  additional tube with air regulator   direct  inside/into  original tube.  Eventually the final tube can be max 20cm   longer.

Can you advice me the regulator and tube ?

Sounds like a VERY bad idea to me! The tube would have to be quite thin to fit into the 78 air tube. If the regulator were to fail, it would expose the QB tube and valve to the 4500 psi. A much better idea would be to get a tank block, and a Ninja 1100 psi regulated 13 cubic inch tank. Dozens of shots per fill, and with the 1800 psi burst disk on the low side of the regulator, MUCH safer!
