Hello all,

I am looking to buy the front (not the stub) part of a g36 receiver that has been left over from an SL8 conversion. I am under the impression that it is essentially a worthless piece of plastic, but I have been increasingly working with CAD and figure that getting the schematics right in order to make a g36 / sl8 receiver is something to aspire to (fool's errand most likely, but you never know until you try). If anyone has one lying around and wants to sell it let me know. ty

I would also add that the front end of the G36 receiver is not simply junk parts as they can be reassembled to create a new G36 receiver that is limited to semiauto only. The difference being the serial number may be located in the "correct" position and there isn't the window at the stock latch.

Ah, I was under the impression that what is left over from the G36 receiver after the rear stub is cut off could not be used to assemble another firearm. At any rate, if anyone is willing to sell I am still interested.

Demilled G36 kits often come with the forward portion of the receiver. (Forward of the serial number anyway.) This area includes the metal barrel trunnion. It may also include the metal rails that the bolt carrier rides on, depending how far back it was cut when it was demilled. Like the others said, this portion isn't normally used in a conversion. The entire SL8 receiver is used, minus the very rear. This is where the rear 'stub' of a G36 is plastic welded on.
Anywho, someone is bound to have the piece you want, probably for a very reasonable price too. If your CAD doesn't work out, they make interesting paperweights..!

I already have the entire receiver in CAD and have printed an FDM sample. Im moving to aluminum next. There are still 5 patents valid on the G36 so things have to be done carefully to not infringe on their patent. Ive been working on this on and off for two years already

lol probably one of the most highly sought-ought paper weights out there

Any idea on when the remaining patents expire? I thought all were filed in '94 and were set to expire in '14

Im just commenting because its a small market and Im very close to making a version of these receivers available already. I have lots of time and money invested in making this happen and I know what it takes. I have built more G36 clones than all the G36 conversion people combined and I have been building these since 06. Your welcome to jump in, I just wanted to put it out there because it looks like your new to the boards and don't know allot about the G36.

The bolt carrier does not ride on metal rails in the G36 or SL8 receiver. There is some metal on the bottom "shelf" of the SL8 receiver along with plastic that prevents the insertion of the G36 bolt carrier. There is also a metal piece that reinforces one side of the receiver on the non ejecting side of the receiver, but it is not for the bolt carrier to ride on.

I'm really looking forward to seeing it. Sounds like that receiver will be a nice home to my G36C kit that has been resting in a box for a while.

Thanks for the catch Sweersa! I must've been thinking of that piece. Clearly I need to spend more time with my rifles.

I am most definitely a newbie to the forum / platform and I appreciate you giving me a heads up on your current progress on the same project. Even if I were to create something resembling a functional receiver, I know the quality would be no where near what you or anyone else with experience and resources can create. Still, I am in large part interested in the process / challenge involved and not just the end result (and at least I know now that there are more much capable hands than mine out there working on this).
