Yep, I can relate. The body took me almost 9 months to decide on. In my case I designed my parts then trued to come up with a unique design. I wound up with a tube gun after many months with a previous design. The reason is the body can be expensive to machine and then you have to gun drill which is spendy. In your case I believe you can buy the commercial chassis and use that. I could not being that I am dead set on springs for several reasons. Then again that SRS is $2500 for the chassis if I recall. I looked into way back when. At that price it is cheaper to mill your own or have a machine shop do it.

Here is a custom one a guy had milled, it does not have the barrel mound though. Good luck!

I'd go for minimal. Get the function working then adjust the form. Reduce complexity for a first go, focus on function not form. The function is the hard part. I vote for stripped PWD MR30.


I would say do not do what others do, like bolt a Tanaka on a square tube and call it "fabricated", then maybe bend a strip of metal can call it a trigger guard.

If you are going to be a bear be a grizzly.

Ha ha ahhh yesssss......

Have you thought of going original? I can maybe help with making of parts or a part so you can have one in hand to get going. If I can find time. I can talk design with you but I am not a gas guy so I may be limited on that aspect.

I found one I got one part i hand that I decided on, the spring guide in my case, it all became ore concrete. Not doing something is a good way to burn out.

Hell I have some ar15 triggers I can send you. Hey, your first part! pm me if interested or want my number.

Look at using an AR15 trigger too.

It has all kinds of problems but to be honest it can be improves quite a bit. While l can not say what I came up with I can say I came up with 4 different designs. Bucking is fine and makes auto feeding easy although it can be improved. Think big ass thick bucking for starters. I would start with super sizing the thickness and length over the barrel to seal better. But then you have to make molds and cast them and you can the have size issues trying to shoe horn it into an existing design etc etc.

There are other ways I think, that is the rethink part. Think through it.

Step 1, CLEARLY define an objective.

An objective of yet another gun designed the same way other guns are is just another same old gun that looks different. The only thing you do is then change the aesthetics. If that is your goal, your golden. If you want a gun that is "better" define "better". Then design the physics around that principle or objective.


Use CAD or any 2D drawing program to help visualize. Google sketch is fine even.

Good luck!
