AL Mag bodies

[fearc7]

cool gj guys i didnt know that stuff!

Just curious, how many people on this thread are engineering majors? I worked in my school's engineering shop doing this kind of thing, so I'm really interested, possibly even in reproduced your work. When you're done, do you think you might post specs here? Take your time, make it rock!!!

twist locks

the twist locks (standard spring plungers) are also made with a threaded body so they can be screwed in from the outside.there is a small pic at the link below.they cost about $3.

me and my friend are about a week away from having some aluminum bodies done. what we did was take a micro mag body and use it as the model, we used a stock vert feed tube from my bushmaster and it takes cocker threads. we are working out the final millings still but these hunks of al are shooting I tell yas

Have you used an all-aluminum construction or do you have steel inserts in there as well?

I have built a aluminum mag body and you do need the steel insert that proteam uses
my first attempt didn't have one and the spring gouged the inside of the body to the point where the bolt would no longer cycle

So as you can probably guess by my questions about the insert, I'm interested in building a body as well. For those of you have done this (or are also thinking about it) how did you secure the steel insert inside the aluminum? I'm asking particularly in the case of using standard mag barrels, which probably complicates matters.


Also, another option instead of using an angled twist-lock to allow the use of standard p/f barrels in a center feed config would be convert the barrels to center feed. There's a thread on this here

I pressed the insert into mine if you want i think i still have the dimensions at the shop I can look if you want

Good luck everyone. Only thing I'm asking for is the weight of your finished little hobby projects.

rather than pressing, you could get the steel insert and pop it in some liquid oxygen or helium to get it extremely cold. The metal would contract and you could put it into the body (with tongs of course). As it warms up, it would expand to tightly fit the body. That way no machinery would be needed.

magmonkey, I'm interested, sent you a pm a while back

Thank for the freezing idea FreshmanBob, I can't say if it will work, but since I've got liquid N2 handy it may be worth a try.
