Build a personal STGW57 semi from currently available parts kits????

[huntgrouse]

New to this realm of builds.

I have gotten the bug for an SIG STGW57 or variant.

I see lots of parts kits available now.

I also see new manufactured receiver sections.

so, my questions:

1. how do you comply with 922R when doing a build with the current parts kits?

2. who offers sufficient US made parts for an STGW57 to make a 922R compliant rifle? seems like no one is offering enough US made parts of rthe STGW57 parts kits to make them 922R compliant. Or am I missing something?

3. now we have the ATF issue of non compliance for auto versus semi auto receiver. since ATF doesn't have model specific guidelines, how/what do you do to be safe and legal. 

I want to build one but will not do anything that is not 100% legal. 

Thanks

Here are 2 places that most people start.
The semiauto receiver pieces from Honeycreek manufacturing:

HoneyCreek MFG on Gunbroker

A source of US made grips as another 922 part

US made STGW-57 grips on Gunbroker

The barrel is one of the harder items to source as it has an unusual chamber.

Several folks have said they are working on barrels.  So far, none have made any available.

so, is anyone making any parts to do a legal 922r compliant build?

I see receiver replacement section and  pistol grip are available. 

who is looking at making barrels?

does anyone have a spec for barrel? (profile dimensions?

would it have to have fluted chamber? I think not for non combat conditions use. If so, an HK91 fluted chamber barrel could possibly be remachined/adapted possibly? they have fluted chambers.

 

based on the images of kits,

looks like trunnions, bolt, bolt carrier, trigger housing, trigger, hammer, sear, disconnector,  magazine body, follower  would be the original parts that probably have to stay and no one will tool up for them. thats the max. foreign  10 parts .

what do you think?

There is a barrel on GB right now.  The seller indicates this one is to test the market.  No matter how it works out, this will be pricey!

The barrel on GB is for a SIG AMT.  AMT barrels are chambered for 7.62 NATO any they are shorter than STGW 57 barrels by about four inches.  While building a SIG AMT sounds nice, you will see that SIG AMT magazines will cost $400+ while STGW 57 magazines cost ~$100.  These magazines are not interchangeable.  I have been told that early STGW 57 magazines using steel followers will work on AMTs, but I have never seen that happen.

There is an AMT barrel for sale.  But, I was referring to this one:

And if you can point me at some $100 PE57 mags, I'd love to get some!  Lowest price I see is $185.
