Drulov 10 air pistol repairs.
Top Gun Airguns no longer carry them and were not able to help me with repairs in the past. A company overseas I believe Magic Nine repairs them but said they could not help because of the shipping regulations. They also cannot send me the parts as there insurance does not allow them to do business in the USA due to the litigious market. They also could not tell me where to obtain the seals. Looking for help.
This is his email--I am afraid that without paying an additional £1500 for insurance to sell into such a litigious market any transaction will invalidate my insurance entirely, something I cannot risk.
I haven't had the reason to do business with Magic Nine Design and Nick for some time and that news is to bad
have you seen this video
now it could be a bad o-ring or just a piece of dirt on the ball a seat, I'm guessing it is leaking
the O-rings can be measured and found the ball and seat could be cleaned and do you lube it, in any case the repairs could be done in house, yours
always wanted one of these pistols but the parts availability was always a problem and oh the price
I will be email old Nick
I faced a very similar situation (more than once, in fact) with Tau MK08 PCP pistols I bought from the gentleman that bought out Top Gun's inventory when they went out of business. Steve at Pomona Airguns was the only person in the U.S. with knowledge and (HAD) the parts to reseal those 2 Taus. But when one of them took a big dump a couple years later, THANKFULLY Steve said he could fabricate a valve (stem) better and stronger than the original that literally broke. He did, and it's better than ever now. He might be able to help you too.

I would bet it is a bad O-ring or a little bit of something holding the valve open
if you don't have a 6 inch stainless steel ruler I would buy one , it is easier in most cases to measure O-rings
I use this one and have many because I use them all the time, a very handy tool
I would give it try first and if that fails find some help
good luck and do keep us posted on your progress
there are just 2 O-rings and one looks to be a standard size that is used on all Czech air piston piercing caps a 19mm ID x 1.5mm thickness, it should be urethane but that size can be hard to find and I don't think the factory use urethane
if I find a source I will post
this is a inch O-ring but very close to the caps size it is .33mm over size on the OD
and I'm now sure if I would use a 90d or 70d but know myself I would order a handful of all of them but that is just me
