I have been patiently waiting for sunny @ xisco canada to get the bulk adapters in,but it seems to be a long wait and with the cold weather coming I really want to be able to use my hpa tank on the qb.
On the other canadian airgun forum sniper (who I think has tried every make but the maxzbulk) gave me (us) the details on the parts and service he recieved ordering from the usa.
Unfortunatly that thread is now buried in the forum with no search option.
If you have the time can you give us the benifet of your experience here,where people in the future will be able to search it up without spending hours going back through the threads page by page?
It seems to be a topic of intrest for all qb owners.
thanx,Keith
bulk parts for QB (hi sniper)
Hi keith,
It will be along wait alright, the last stock that I bought out of Sunny was the last stock of the US and it was the last 3, and I bought 3 more set of Mac1. They are different valve systems between the two. If you are going to use it with hpa tank than your best bet is to go with the Xisico one since the cap thread made for hook up directly to the existing tube. The Mac1 is only fit to the mac1 extended tube and on one end of the tube has thread that fit to the QB.

When I ordered my QB the bulk caps were sold out, so I decided to make one myself. It's not as hard as you might think, but I can't recommend you do this (liability reasons).
The only thing you would need is a lathe. I had a spare 1-way quick connect and a short bar of brass roughly the same diameter as the QB's pressure tube. I copied the original part that sealed the tube, but added a threaded hole in the centre. The cap hole had to be enlarged slightly. It works great and best of all it cost a fraction of the price.
