Qev 8 mm multishoot sniper rifle. i got some prob with accuracy but its the barrel. when it was new i had pretty good precision like 0.5 cm spread by 10 m, now i got 30 cm by 5 m. i use steel ball bearings . It is entirely made of reused stuff i got in my garage. i did not use special tools to make it. i get 20-25 strong shoots per one fill. this fun is capable to do lots of damages like smash bricks....

this gun i made last year, now i am allmost done with a 6mm semiauto sniper airrifle, just working to the stock

Great work and nice attention to detail! I would also like to see a video, and, something you could probably do sooner, what kind of scope is that?

Nice one bravo (thanks for answering some YouTube comments for me BTW).
For higher accuracy a cheap rifled barrel would be quite worthy IMO.
Keep it up!

If you are gonna use a rifled barrel then you may want a ammo that is much softer than the barrel copper= plastic or less 8)

yes, but sometimes i am able to hit the same hole by 15-20 m. i havent seen over the internet a 8 mm airsoft barrel in my country. maybe if i use an innox solid pipe that does''nt get used, or new ammo..

Don't be limited by airsoft barrels, there are plenty brass/aluminum tubes of various sizes.
Ball bearings aren't the most accurate ammo, use lead pellets of the correct size would improve a lot, even on a smooth bore.

it is a qev, a pilot valve made by me and a 3rd valve that portion the air exausted by the pilot valve in order to activate the qev. i can easy set this 3rd valve for high power(less shoots), or more shoots( less power) I did it like wizz2285 videos from youtube. on this gun the valves are inside the stock, but when ill post my other qev you will see, i put them outside for easy setup the power.

i got some good projectiles made of superglue cap with a nail- very good precision but it takes a lot of time to make them and waste for target shooting. expensive are those ball bearings, so i recolect them after i shoot.
