My new 1'' sniper rifle

Unread postAuthor: mister pointy » Mon Jul 21, 2008 8:44 pm

I finally finished my sniper rifle so here it is.

2'' chamber, 1'' bolt action barrel, 1'' modified sprinkler valve.

I made the bolt action barrel for another gun, so i built this gun around it.
The stock is removable, the two tee's are blocked off.
I really struggled with getting the epoxy to seal off the two tee's, i ended up getting a high strength epoxy which flowed better to seal off the leaks that the jb weld couldn't seal effectively.

I shoot corks with a little bit of electrical tape wrapped around them for a better seal, and screws in the tips for stability.

Performance and accuracy are pretty good with the cork bullets, unfortunately, i have no damage pics right now.

i think eventually i'll put a scope on it, what do you guys think?

Awsome, wish I had Money to make that many sprinkler valve cannons, and does air flow through your stock?

No air flows through the stock, sealing it off was the hardest part of this gun.

I got really lucky when it comes to valves, i got 4 for free from my shop teacher a couple of months ago. 2 inlines and 2 jar tops. i also found 1 inch valves at home depot for 11 u.s. dollars. I bought two and i used one of them on this gun.

so right now i have only 3 sprinkler guns. i've more valves than guns :lol:

Even if it does, it is fine. It won't hurt performance at all. Maybe even on a small enough scale, it might improve it slightly

Of all of your collection, I predict this one is your best performing, just from barrel length, dead space management (your sprinkler valve in a better position), etc.

I like your double barrel combustion too...nice wooden stock...I bet loud too.. :wink:

Simple and solid. Good job.

Thanks for the compliments.

i have kept my barrels a little short on my other guns for the sake of portability and ease of use. This gun is definitely the longest out of all of them.

@starman: my double barrel combustion needs to get finished, i started it as a way to try a simple wiring for a grill sparker ignition, but i never finished up the stock, and cleaned up the wires. When i get around to finishing it, i make a separate thread for it. still waiting on that propane adapter though,


and yes it is loud, i'm sure you know some stuff about loud cannons huh :wink:

my barrels are just too darn short..
