Elephant Rifle mk1 and mk2

[Major Collins]

My first rifle post in joining this forum!

Well this is my 1/2 inch piston valve rifle.
The barrel 16mm(roughly)x65cm long steel. Fits marbles nicely. Preferred ammo is homemade plastic nail darts.
Blowgun pilot
soldered in schrader valve
Air chamber is 40mm pvc, goes up to 160 psi ive bombsheltered and tested it multiple times
i have a slighly smaller airchamber that is 40mm copper sleeved in pvc estimated maybe 300psi with it , all i have is a 160 psi bike pump so ive never gone higher than that.

Piston
i took a "do not eat" cylindrical silicon capsule that was the diameter as my piston housing and poured epoxy in it and added a bolt through the middle to hold on a few pieces of inner tube bike rubber for the sealing face.

The inspiration was this

that gun must be powerful i wonder if it would be able to handle a razor dart if you want me to explain how to make the dart just ask also i like the build but i would think that if you are gonna make a better air chamber out of copper you should make the air chamber resses into the fore stock as to not have that huge airtank get in your way and it looks like if you made a pvc or copper bi pod that is relitivly adustable (if you want plans i can get you them) that would fit ressesed into the stockit would be amasing, also maby if you made a scilencer it would be quiet er and look cooler also how much does it weigh

I like your stock. Is that homemade or for a firearm?

[Major Collins]

@Dart guy ive been looking into a coax version and i am working on a supressor aswell. Its quite light , around 2 kg. what are these razor darts you speak of ?

@blitz yeah i carved it myself, its pine wood with a oak stain.

[Blitz]

Very nice. I like the oak stain, it came out well.

[Gun Freak]

Sweet man. Nice work on the stock. I like this gun a lot! How is the stock connected on the back? Also, why not elbow the chamber 90* so it is parallel with the barrel? Video!!

[Blitz]

I personally prefer how he mounted the chamber. Allows you to hold on to an actual rifle stock instead of more plastic/metal, which I feel adds ergonomics many guns here don't have.

It also loosely resembles a stick magazine like from a Thompson M1.

[Major Collins]

@Gun freak thanks! The blowgun is epoxied into the stock, i cut all the excess around the blowgun so it was just a straight tube.Then slid it through a drilled hole in the stock at the correct angle. Air chamber is straight down, its a prefrence thing .Blitz knows what im on about

Though mk3 will will either be a coax air chamber or a bolt action, or both!

[jackssmirkingrevenge]

Nice, I especially like the way you integrated the blowgun into the structure, good job!

[farcticox1]

I like it

[dart guy]

these are 2 different razor darts(out of a masive colection of experimentals these arnt experimental) kinda like the comercial ones but home made so that anyone with a hammer and a metal rod about as thick as a bike spoke the blue one though should have a blowtorch and a pair of pliers and a vice or another pair of pliers
that last dart was shot by a 14 year old at 10-15 feet away from a pvc pipe with only breath power and the twisty leaves a twisting and punching action if shot into a solid block into somthin softish like styrafoam or clay
no darts have been shot from anthin but the pipe and the target is a card board box 1 inch with one side about 3/16 inch thickness
and when i mean handle i mean can it keep it straight at 10 feet and fire at a substantal fps with out destoying the gun like with airsoft by using light bbs or misformed weirt texture or somthin

Well I injured my right hand and I can't do much for the next couple days... Anyway, I managed to build one like thing out of standard parts, fire .177 cal pellets and arrows.
Guess what it worked way better than I thought, at 20 bar it sound like a fire arm firing the .177 pellets and perforated a 2cm thick wood.
It's so simple that I'm considering making a tutorial about it, I think at least it would give beginners a chance to have a nice rilfe.
Anybody back me up on this idea?

Id like to see it Wyz2285. I really like these guns and I think ive seen all the gun vids on youtube.
