the Barret 14mm sniper (NEW VIDEO!)

Unread postAuthor: VH_man » Sat Jun 23, 2007 7:58 pm

Well, ive been on this fourm for a while and NEVER posted a cannon, so i decided it was my time. this is my 4th pneumatic. it features:

-3 feet of 1/2 inch copper pipe (barrel)
-a pneumatically modified 3/4 inch rainbird sprinkler valve
-a stock/chamber made of various 1 inch fittings
-a 3X9X32 Airgun scope and Leapers Weaver rings

Notice that the whole copper barrel is sheathed in either 1 inch or 3/4 inch PVC. the reason for this is 1. to stop the barrel from getting dented 2. to make the ringggg that copper makes go away so i just get a BANG!!!! and 3. to allow the mounting of my scope.

btw, the scope mount is the rails off the top of my broken UTG shotgun.... works great. (i tell ya, ive been able to use every part of that broken thing other than the things that broke..........) the mount simply stays put becuase of the screw protruding from the mount itself. they dig into the 1 inch pipe and hold it more securely than i expected.

NEWWWWW: Video:

Looking down the outer barrel/muzzle brake stolen from my first pneumatic. notice the 1/2 inch copper barrel inside of it.......

A coffe can after a day of firing. this was all from at least 75 feet........ and the marbles were imbedding themselves into my 1/2 inch plywood backstop

the "into the can" view of the damage. gotta say, both damage pics dont do this justice.......

Morpherman: If i use marbles that fit nice then it is quite consistently, providing i brace myself for the recoil this thing has. it has a bad habit of shooting too high because the gun shoves itself upward before the marble leaves the barrel.

also, ive found that using a sabot and marbles that are too small actually work quite well. with those, i can consistently hit the can.

and by "hit", what do you mean. do you mean just nick it or punch a hole straight through?

I love the look of the gun. the paint makes it look great. but its oddly familiar like someones made a gun like this.

Any way i love the scope. it rocks.

yes, i used the stock off of someones cannon that had a 1 inch barrel........

at first it looked like it would be comforatable, but now ive found that sticking my arm inside the stock and resting my shoulder on the inside of the stock actually fares much better. so to whoever came up with the chamber/stock thing, kudos, youve inspired me.

the whole barrel sheath and the scope (as far as i know) are original. im still mad i ran out of black spraypaint...... i was going to do the whole stock black and then do a portion of the 1inch barrel sheathing with 1/4 inch holes so it would look like a heat sink...............

yes. thats the gun i got the idea for the stock from. of course, i kinda made it completely wrong......... lol. kudos to who made that gun. its truly ingenious.

BTW, the reason i call it the Barret 14mm Sniper is because it kinda looks like the Barret .50 bmg.

and for those wanting more pics, here ya go:

The Scope/Mount/Sprinkler. im still amazed how well the mount stays on.
CameraUpload 006.jpg
This is how i hold the cannon. sure, its kinda awkward but its 10000X better than resting it on the rear of the stock.

a full pop can from 15 feet. i had to take a shower afterward, it got me all covered in diet gingerale (Ewww. the stuff tastes like pure aspartame)

thats a nice set up you have there, i really like it. especially the paint job. maybe you could mod the stock a little so it fits you, but it looks good no matter what.

im afraid if i make the stock fit me i will loose preformance....... i mean, this chamber is equevalent to about 3 feet of 1 inch PVC right now, and it takes like 20 pumps to get it to 100 PSI with my bike pump.....

mabey ill make it over/under and make a nice Tee stock or something.
