Seeing that our fine sharpshooters in Iraq were equipped with Barret Arms .50 calibers, I wanted to produce a magazine fed (removable magazine), high powered, big bore, long range rifle. What I came up with was the Artemis Arms Mk. 1 "Mountain Rifle." Here's what I did:
I modified my Titan by removing the air restrictors and plugging the over release valve, just routine things. I then cut a piece of 1/2" PVC at a length of 1.5'. I took that piece of PVC and cut out a breech wide and long (1.5"x2.25") enough to fit a mega dart. Next I glued that barrel to my Titan. Nothing new there.
I then found a nice piece of orange plastic tubing that fit my 1/2" PVC well. I cut a 4 inch piece of this to use as my bolt. I installed the new bolt to my barrel. What I had now was essentially a big bore single shot breech loader.
I next found a piece of a black tube off an old model Blast Bazooka. I Dremeled out a bolt channel and cut my magazine port on the bottom. I then glued on this black piece (we'll call it my "shroud") to my Titan. Finally for this step, I glued on my bolt, which is made of a 4 inch piece of dowel rod, to my bolt.
Finally, I made my magazine. I used a cassette tape case. The case's width is perfect for micros, but I had to widen it a bit to fit my mega darts. I needed a spring. I managed to make a spring from an old grandfather clock coil spring. I hammered it out flat and use a blow torch to heat it up so I could bend it in a "zig-zag" shape. I used several popsicle sticks glued together to make my magazine follower. To keep the magazine attached to the Titan, I made two small clips out of aluminum sheeting. I glued these to the bottom of the Titan. On my magazine, I Dremeled a shallow channels that the aluminum clips will slide into to hold it in place. To remove the magazine, merely lift the aluminum plate clips and pull the magazine straight down. The capacity on the magazine is 5 rounds.
To load the rifle, push the bolt forward and pull it back. This allows one round to be loaded into the chamber.
I didn't get to shoot a lot of rounds outside, but I had a chance to squeeze off 10 rounds. Here's what I got:
Ammo: 2" Mega stefans with 3/0 weight
Rifle primed to 25 pumps.
I also did some testing to demonstrate the power of this gun. Observe:
At 40 feet, I made Swiss cheese of this piece of .5" thick styrofoam with 20 pumps.
At 25 feet, I hit this hefty block of 1.5" styrofoam three times blowing sizeable holes in it. I primed the rifle with 25 pumps.
At 25 feet, I hit this piece of cardboard 3 out of 4 times. It punched through twice and penetrated enough to get one round stuck about half way through.
Using the mega darts in this rifle allows for a heavier round. A heavier round is less likely to be disturbed by wind during its flight path. The mass of the round also gives an extra punch that a smaller micro dart lacks.
As you can see, this is one heck of a gun. To shoot an "unarmored" target under 70 feet would probably inflict abundant pain. One could also honestly drop a target out at 120-130 feet with ease. Any armored target under 70 feet would be dead meat. I'm currently working on making at least two more magazines for the rifle. So, once I can get those finished, I believe this will be a very deadly weapon. And yes... I realize that most people would ban this rifle from a war, but it's still pretty neat.
Hope you've enjoyed a Starbuck/Noid modification.
