You may be inexperienced but it doesn't have to stay that way. Start simple. Most of the guns you linked to above are very complex designs that even the most talented members here would struggle to pull off well without a CNC machine or lathe. I'm not sure how accurate a representation you're looking for but you would almost certainly have to make it from wood unless you can find an airsoft body.

So the design you're trying to make is the one linked in the last picture? Have you built many other cannons before? It's not exactly the hardest design, but you are playing with high pressure, need to mod a piston valve, make a bolt-action, and a magazine. That's a fair amount of work and if you don't have previous experience you may struggle to pull it off.

I would suggest the following: get a rifle stock (similar to your first picture), 6" length of 1/2" galvanised iron pipe, a 3/8" QEV (or make your own), and a CO2 setup (if you have prior experience, otherwise it may be best to just start with a high pressure bike pump). Buy a length of metal tubing for whatever projectiles you want to use (I'd recommend 6mm-10mm diameter ball bearings), find another length of pipe that can sleeve over your barrel (needs to be a pretty good fit). This second pipe will be attached to your valve while the inner barrel is part of the bolt-action mechanism. If you don't know where I'm going with that bolt-action design, I can link some pictures but it is a very common design here.

That's a simple single shot gun that could be taken up to 300PSI pretty easily and I'm sure performance will be very satisfying, especially since you're inexperienced. You will need to find a way to mount the gun internals to the stock but this has been done dozens of times here and there should be plenty of examples. Just buy a scope and you're good to go.

Over time you can modify this design. You can add a CO2 tank with regulator and three-way valve, allowing you to achieve semi-auto. Then you can work on a loading mechanism and magazine. After awhile you'll want a whole new gun and you can start trying to build something a little harder. If you jump straight in to the deep end you may end up wasting money, growing frustrated, and giving up on the hobby. You won't be disappointed with a 300PSI single-shot pneumatic, trust me.

Start simple.

Nice list, I like your style :D The only one I didn't make is the M107.

If you're going for a replica straight off the bat, I have to recommend the L96. It has a wide chunky stock you can fit a large air tank into and there is a lot of room in the front for a working magazine feed system. The rifle doesn't have too many complex curves so it would be the easiest to make.

I would start with making a 1:1 cardboard cutout and placing the internal components from there.

“The combined synergy of a man and rifle is matchless.
The steadiness of hand, the acuity of vision and finally
the art of knowing how to make the rifle an extension of the
body all equate to the ultimate synthesis of man and machine.”

I didn't even know people made their own air guns until a few months ago, I started simple and got more complex with each attempt, this is my latest completed. I have no special tools, just a hacksaw, lots of files, materials, and imagination helps. If I had a machine shop it would be a different story.
mmmm the possibilities :idea:

i finaly have bolt action plans for the l96 rifle and i am not foing for a replica i am using it as a basic desine so i dont screw up i will submit pic soon
Image
ther is a qev valve and after that is a presure tank that should also be able to be loaded with a compressor or a co2 charger sadly it probably wont work well in cold weather but i have a veiw of the bolt actoion the green is in the middle and the mag is orange at the end is a scilencer with end fluting the grey is the triger bat that will push a slider valve this is just a basic desine i might chang it to make the tank removable and the trigger is basic also i need a finished bolt eqector so please post ideas
