Sorry but that's not great accuracy from a vice at 10 meters. It's a result of the smoothbore barrel and projectile.


yeah i know its not great but i can hit a softdrink can at 14m with my first shot with no form of sights so im happy enough :)

Well what are you waiting for...slap some sights on! But it's a very nice gun. You'll get the accuracy issues ironed out easily, I'm sure. Good work!

That's quite a beautiful gun you've made! If you can afford it, you could mod the air tank to fit a PCP pump, and then you'd really be in business. :D

the stock was cut from a single piece of wood, then the relief for the air tank and trigger etc. were cut into it. it was sanded and painted with 2 coats of rich jarrah gloss varnish. (the stock from start to finish took 2 days.)

this is the main workings of the gun. refer to the labels to see how it works.

breech over the 4.5mm inside diameter tubing. sorry but this is something you will have to figure out on yours as it is different for each gun.

the end of the air tank and barrel, the bracket was made from some stainless steel plating.

Would suggest you try swagging the pellet skirts up in diameter to fit the bore well...should have to push them in a little...if they fall right through...accuracy will definitely suffer.

Nice job on the build. :)

Yeah they are fairly tight in the breech, once the pressure drops too low sometimes they get stuck.

He probably got them from a supplier. And you shouldn't "kick up" old topics, this topic is about 4 months old..

I'm pretty sure that was lost in translation, a bit like shoulder launched cannons :D

Hi,
A short question: you said you pumped to 260 psi, but i'm wonder if it is safe for the QEV with that high pressure (when the working pressure of such 1/4'' valve is approx. 150 psi ~ 10bar)?
Thanks!

Some folks have taken 150 psi rated QEVs to 500-600 psi with no issues other than increased diaphragm wear. It's never a good idea to exceed the manufacturer's ratings, but in the vast majority of cases as long as you don't overdo it, it's unlikely that a catastrophic failure will occur. At your own risk, of course.
