Recently I got a lot of good stuff, hydraulic/pneumatic parts, etc.
So, I decided to build a airsoft sniper rifle, my objective it´s to see how accurate a airsoft bb can be.
I used a 1/4 3-way valve to pilot a 1/4 QEV, the exhaust port of the 3-way is suppressed. But I´m not going to make it semi-auto, instead I will use bolt-action plus magazine for reloading.
The gun isn´t finished yet, I still haven´t decided the barrel/bolt configuration.
Video made at 5 bar, I tested 10 bar after the video, the QEV really rocks off the ground :D

Thank you sir :P
By my stuff getting better and better you meant the scope isn´t it :lol: actually it wasn´t expensive.
For the valves, I bought like 10 DCVs plus a couple of QEVs and other parts for less than 100 euro :P :D also now I have 6mm steel bbs :twisted:

Thanks dewey-1, BTW I also got the circuit boards printed, 20 copies for just 30 euro :D
Hope I can finish this gun this month, but I have a girlfriend to take care now :?

That looks really nice, you should make the barrel come out of the grey tube.
Where's my Chuck key?

And, why should I ask JSR :lol: ?


Well, the poor guy was once forced to bake a cake...
Not to mention he isn't allowed to buy a robotic baby.

Well currently I´m not "forced" to do anything yet, but there are stuffs that I know I shouldn´t do now :roll:
I do have a barrel, one of the best I have right now :) but I need a new 6mm barrel source, any details?

I can get 6 mm ID, 10 mm OD hydraulics pipe very cheaply, in reasonable lengths. (up to 2 meters)

They are made out of 316L stainless, I need to do a precision measurement on the ID tough.

Price? If the ID is less than 6.1 mm it´s ok, but it has to fit a bb of course.
And are they straight? Keep 2m of 6mm tube straight during shipping it´s difficult I guess.

Have to agree with everyone else...that IS looking good. :thumbup:

Kind of a Condor/tube gun thing going on that has major appeal. :)

Very very cheap, someytimes I can even get 60 cm lengths for free.
I believe it's under 6,1 mm, fits a bb very well, I already tried.
I'll test the straightness tomorrow.

Nice work Wyz, looking forward to seeing it finished.

I hate to ask too, but you didn't pick her up fairly cheap in China did you?
