How to build a inner barrel

[-=Blood*Shot=-]

hi guys,

i might have posted something that ressembles to this but how can i build a inner barrel for a sniper rifle because i am more to building one than to buy one. If someone sells a sniper barrel, tell me and ill see wat i can do. If you could show me the steps of creating one that would help. My sniper is the Maruzen APS-2 MK2

well, thats kind of almost impossible to do. I would highly suggest getting the barrel. Because in order to work for airsoft the inner diameter would have to be the same all the way down, and would need to be in the 6.05-6.06 mm margin. You theoretically could do it, but good luck.

I thought of the same thing. It's going require alot of time, alot of measurements and you need to know the diffrent type of metal and grade. Some are too soft and can bend easily and some are too hard and takes too long to cut and drill. Also you got to concider that metal are never perfectly smooth on the inside so it going to take time to fix those imperfections. I personally think buying a inner barrel is alot easyer and saves you time but if you want to make one experiment with metals and how to do it. The most important thing to rember is that each hole you drill or each cut you do think it over acouple times before you do it.

Inner barrels (even precision ones) are typically extruded Brass. There are some exceptions though. Brass would be the easiest (and cheapest) to work with.

As long as the mould you're using has a precise and polished extrusion head, you can get away with it. Keep in mind of the heat levels so that as it cools, the barrel doesn't warp, then you should be okay.

Once it's extruded, you would need to turn it with very flat ends, de-burr it, and crater cut the exit end of the barrel.
The mounting end will need to have the mounting locations milled out.

Once it's manufactured, you can get fancy and coat it for extra durability/smoothness/self-lubricity with the various options available.

In the end, the cost of doing such a project isn't worth it when there are barrels already pre-built for your purpose. The cost of making the mould alone, plus acquiring the raw materials and running several samples before you get it "right" will end up costing more than just buying a precision built one from the start.

Even supposed "custom barrel suppliers" from the US never manufacture their own barrels. They just buy in bulk from Japanese airsoft barrel manufacturers and from there, they'll do the milling/turning as required.
