    So i finally got back into building my homemade nerf rifle. My goal was to build a springer with some godly ranges that looked like a Barrett m82A1.
    The internals of the gun will be nearly identical to the longshot in design. It will have a PETG breech very similar to an angel breech and the bolt section will be removable, so you can completely disassemble the gun. The barrel will feature a screw in feature so that you can replace the barrel with another material (eg brass) if desired. The point to this was to allow for a tighter barrel using 16mm pvc. However, 16mm pvc is too tight for a clip system and the darts must be loaded by hand. Point is you can chose between singled, more powerful fire, or clip-fed, weaker fire.
    I hope to put a 20kg or higher load spring in it and am hoping for ranges of at least 80m.

    UPDATE 30/05/2011

    Comparison against longshot plunger:

    System as it will be in the gun:

    All the parts separated:

    Breech system:
    Home made Nerf Barrett sniper rifle (Picture Heavy) Imag0115

    Catch knob and location of catch:
    Home made Nerf Barrett sniper rifle (Picture Heavy) Imag0116

    What i have done so far:
    Made plunger tube.
    Made rear section of breech including bolt attachment, minus bolt.
    Plunger rod with catch knob on the back end.
    A piece of aluminium tube sitting behind the plunger against which the springs will compress at the front, and the trigger catch will sit at the back (the point of this is to have something strong to hold the spring's force).
    I have prepped the material for the catch. (I had to epoxy two pieces of 2mm steel together for a thicker piece).
    Again, i will post pictures of all this when i can.

    What i have yet to do:
    Make bolt.
    Make catch and trigger assembly.
    Make case including magwell and clip release system.
    Make barrels.

    I will update this whenever i work on the project.

    I'll be interested to see a springer hit 260 feet or better.
    That plunger tube looks about the same size as a PAS, so that gives you a fair bit of choice for springs.

    I use a clip-fed barrel on my Titan, with petg. What do you mean by the clip-fed barrel being weaker in regards to range?

    Cheers,

    PETG works better than a tighter barrel for air guns, as friction slows down the dart. A bit of friction in a spring powered gun allows the plunger to build up higher pressure before the dart leaves the barrel.
    I have had an idea of combining a tight barrel with a perfect fitting PETG barrel. I figure that the friction of a tighter barrel will be good to let the plunger build up pressure, but then you'd want a looser barrel in order to apply that pressure. So you start with some length of 16mm pvc which is fairly tight on the dart, and then have a longer piece of PETG connected to it.
    When i get my PETG from informer, and after i've managed to obtain some longer lengths too, i'm going to start barrel testing to test these ideas out.

    Good work!

    Have you been taking plenty of photos? I'm sure I'm not the only one interested in a write up!

    This looks pretty amazing. Is this going to be in a nerf shell or a homemade shell?

    I will have two shells for it. One will be to look like a Barrett .50 caliber rifle. I will also be gutting a titan shell to mount it in so i can use it in public wars.

    Nope, still making the internals. I'm close to starting on the shell though. Not really sure how to do it yet though.

    If you have access to injection moulding equipment, and a milling machine it should be easy to make a blaster shell.

    Albeit, fabrication costs...
