I'm looking for detailed complete disassembly/reassembly instructions for a full auto STGW 90 grip assembly. Any help would be greatly appreciated.This message has been edited. Last edited by: MG34_Dan,

Thank you. Your pictures should be more than enough.
I have a complete full auto parts kit and am trying how to convert the trigger pack to semi-auto only. But from my playing around, it looks like the full auto trip finger must be depressed even in semi mode in order to reset the trigger. I'll figure it out, eventually.

my understanding is that you need three things; F/A lower, F/A bolt and the inside rail of the upper needs to be machined to allow the fingers of the F/A kit to work. You *should* be able to use that lower on a semi-upper as-is. That said, the US bolts are F/A - the Swiss ones are not unless surplus kits.
I've got some pics saved somewhere showing the upper and the bolt differences.
Obviously you don't want to accidentally step over the NFA line of course.

Look what I just found on the inter-web.

Here a PE 90:
Here a 550-1, which is the same as an army Stgw 90:
And here an army version which has been converted to semi-auto:
This is exactly what I was looking for. Now all I need are the specifics of the components.

Don’t over complicate this. The easiest solution is to pull all the FCG parts from the lower, set aside the fullauto sear, semiauto sear, burst mechanism cassette, and automatic sear release lever. Use a single semiauto sear, which takes up the same width of the dual semi/auto sear, replace all other parts. Another option is to mill off the catch surface from the automatic sear so that it functions as a spacer and no longer can catch the tail of the hammer, remove and do not reinstall the automatic sear release lever and burst mechanism cassette. I would personally keep the fullauto parts because they are becoming less easy to find, buy a shooting sight hammer and sear. It’s very simple. It may make more sense to discuss by phone. If you wish to do so, drop me an email through the board and I’ll get you my phone number.

Josh; Thank you very much for this information. I didn't know Shooting Sight existed. Use of their hammer and sear is definitely the way to go as I do not want to damage the original SIG full auto components.
