Buy a tight bore airsoft barrel, a short one should be quite cheap. I'd agree with this... Airsoft TBBs are droping in price when compared to a few years ago. http://www.airsoftgi.com/advanced_search_result.php?keywords=tight%20bore%20barrel&inc_subcat=1&sort=2a&categories_id=328 Cut off the hop-up...

Yeah... in the airsoft world they are called buckings; and buying one by it-self will run you anywhere from $5-$20 unless you can find a place to get "stock" replacements, then you're still looking at $3... so you'd still be better off just getting the whole pistol.

You should make your chamber an air cylinder with a heavy weight and a strong spring. That way, when you fire, all the air is exhausted very quickly and the spring forces the heavy weight backwards, causing "kick" This was an original thought, as well as balancing with an air spring and a sealed pi...

I have a Palmer regulator that I plan to use, but unfortunately the stock is built into the lower receiver.

I had thought of something like that, but I think it would get a little gas consuming. Unlike a lot of airsofters I wouldn't mind carrying a tank externally, but within reason lol.

Well, the top bolt would be completely redesigned. Off the top of my head I'm thinking alumnium sealed with a spring loaded nozzle, with the rear section rigged like a QDV. Since airsft is only 6mm, the nozzle assembly would probably be more than 10-12mm D. The recoil however would be from, what is ...

In the time being I think I found an animation that is similar to what I am thinking:

The main difference would be in the bolt design. I think I would have the vent for the recoil device drive the nozzle forward to load BBs.

I have seen that system and was interested in it until I fired one... its kinda wimpy, not to mention its just making an existing mechanical system that breaks more complicated.

Ill have to see if I can get a sketch up when I get home tonight or some time tomorrow.

Hello all. So I have been thinking about an airsoft conversion for longer thank I care to say. Now, if I just wanted to make it shoot there are tons of resources here and I have done enough playing around that I could make that happen. However, there is one thing I want to add that I am not sure how...

Mp5 = A V2 mechbox. Depending on the body you can rebuild the box you have, but chances are that it wont last, and you wont have room in an MP5 body for the amount of epoxy you'll need. The only one I've seen that worked, the guy layered carbon fiber over the whole mech box.

Oh, my mistake, its obviously been a while since I've been around these parts Sorry for the necro post, I figured it was still on the first page, but now I see I was about 2 months late to the party

Nice work JSM!! I have been thinking about something like this for about 6 months to put in a semi auto airsoft sniper rifle, and lo and behold I come here for some inew inspiration and I see this! Absolutely awesome work!

Right now all I have is the typical assortment of hand tools, drills and a dremel (assortment of saws and such, but those aren't really applicable to this). Although I have decided that this would be an excuse to get a decent drill press (most of the ones at local stores though are just cheap build ...

Awesome thread, its killing me that the photo links are bad though! I do remember seeing your ammo before, but like I said, I dont have an injection molder :cry: and the round I am thinking of seems like it would be a little more complicated to make a mold of (I really have no idea, this will be the...
