UPDATED Pneumatic Sniper Rifle

Unread postAuthor: qbnbountyhunter » Wed Nov 28, 2007 9:25 pm

This is my best sniper rifle, it looks, feels and shoots like a real rifle. I pump it up to 120-180 PSI and i use a marble with wadding for ammo. I havent chrono-ed it yet, but i hope to but it rips through one full inch of dry wall and it shreds tin cans at over 30 feet. it is accurate over 100 yards

The Rifle Parts:
half inch PVC rated at 600psi
Sprinkler valve
Blowgun
Shrader valve
Red dot Scope
RIS rail
Cardboard
News paper
Glue



I paper mached the stock and fore grip for comfort using newspaper, glue and cardboard. NO TAPE!!


i will try to post a video to show its true destruction

Good job but....

This is the best sniper rifle, it looks, feels and shoots like a real rifle. I pump it up to 120 PSI and i use a marble with wadding for ammo. I havent chrono-ed it yet, but i hope to but it rips through one full inch of dry wall and it shreds tin cans at over 30 feet.


There hasn't been any sniper rifles on this site EVER, since the barrels aren't rifled nor are you are meeting the infamous requirements said by some random spudder.

"You aren't allowed to call this a 'sniper' until you hit a 5"x5" target at 500 yards, and even that is being generous."

Or hit 2 MOA or less at 100 yards.


"half inch PVC rated at 600psi"

Where did you get that?

i have used this gun to hit trash cans at over 100 yards, and i say it is the best sniper rifle because i have seen alot of posts claiming to be a rifles or marble sniper and im trying to show what a real rifle looks like.

the pvc is from homedepot, but it is rated for water pressure not air

@octane89

The dry wall damage is in the background, look and you can find the holes behind the cans (sprayed with silver paint so know where each shot was)

@Zen//
thats a cute rifle, but it looks awkward to hold and bulky, but it is nicely crafted with a bolt action breech.

@Mitchza89
Thanks for the reply!

dents and rips in the tin trash cans

i use this rifle mosty for scaring off crows and opposums in my neighborhood

btw the 25 mm bolt action rifle doesnt seem very acruate from the little video on the instructables. if you wtch the video, the ammo hits low to the left of the target

P.S. i changed up the post so hopefully it will make everybody happy :)
