laser sight marble sniper rifle

jave101 · Sat Mar 11, 2006 10:44 pm

this my sniper rifle that i made afew days ago its accurate to about 30m. i can repeatedly hit a telegraph pole from about 70m away. the laser sight is 1x magnification attached to a very ridged stainless steel barrel that fits marbles. the pressure chamber holds 100psi filled with a tyre valve. i painted it olive drab and im thinking bout spraying the barrel aswell.
i've also made a smaller version that doesn't have a stock that also shoot quite well.
they're both made out of PVC pressure pipe and modded sprinkler valves.

WOW! Very nice and clean gun! Awesome job on construction and paint. What brand of sprinkler valve is that? Doesn't look like rainbird or watermaster. Where did you get that sight from? I am thinking about getting one off of eBay. Again, sweet gun and welcome to the forums

i see you pluged the hole for the solenoid, what fitting did you use to attach the blowgun to the valve?

nice gun, i have one myself alot smaller though but i have had about 130psi in it which really canes. would only drop bout 2 feet over say about 100 metres but it currently has a hole in the expoxy that is on it but that is in the middle of getting fixed so should be up again soon.

i made up a fitting that screws into the hole for the solenoid. its a 3/4" UNF end cap, that fits into the solenoid thread, drilled and tapped to 1/2" UNF, then the blow gun was attached with a 1/2" union fitting

pure jealousy here. very nice sniper. is that scope accurate? i really love how u attached the blow gun into the solinoid hole, idk how that works but i guess it does. good job

Edit: Scratch question on scope accuaracy, i re-read post, and kicked myself in the butt.

Nice gun and nice color. how much did the scope cost?

you could make that barrel more accurate by adding a piece of streight extruded aluminum to the barrel and strapping it on

jave101 · Thu Apr 06, 2006 8:16 pm

the scope cost round $55AU off ebay.
the barrel is 1/32" thick stainless steel so thats things about as straight as it can be you cant bend it at all. i've also made another barrel with an intergrated silencer which reduces the noise by about half and im planning to put a pressure guage on to the tank
