    Thanks!

    So if I screw one of these on my QB78D and then attach a 3K PSI ninja tank regulated to 1600 PSI, am I good to go? Or does something need to be replaced as well?

    You have to make sure that the regulator has a 1.8K burst disc on the downstream side to protect the gun in case the regulator bypasses, you don't want 3000 psi in the gun.... 1500 may be the max without blowing the disc, and if you don't shim the hammer spring, there is no point going past 1200 psi anyway, the velocity will just drop....

    Better quality screws to attach the tank block are a very good idea as well, the stock screws are soft....

    Good Night to all members, I'm new here on the forum, and I've been in search of knowledge and sharing of information, I am Brazilian and may provide the name, and I signed up online because in my research I saw that this forum works fine changes in QB78 rifles, SMK, AR, all of the following ...

    I come to ask members of the forum where I can get a block to tank so I can adapt an HPA 13Ci in my rifle, I tried on two sites, and scopesandammo archerairguns, however none of these send to Brazil, could someone point me to another site that Works with this product? or even someone who has this piece and wants to sell and is willing to send to Brazil?

    Thank you, Good shots everyone ..
