Anybody have a spare stock take down pin or a Midwest Industries.  Steyr Aug would work also.

Looks like Gearhead works is out of them too...

I would suggest calling Steyr USA to see if they can sell you one (along with the spring if you don't have one of those).

They have a lot of bits that aren't on the webstore, and if you ask nicely my guess is they may sell you one.

I am pretty sure I have a spare OEM. I’ll have a look this weekend and let you know.

Need the pin for the butt pad.

I think everyone thought you were looking for the crossbolt piece that holds the stock to the receiver, and didn't realize you were looking for the pin that holds the buttplate on the stock.

I will confirm tonight, and it has been a long time since I goofed about with swapping parts, but 97% sure a standard Steyr AUG pin will work on the MSAR.

Yes, the Steyr Aug will work in the MSAR but was hoping for the QD on the MSAR and MI.  Steyr lists them for sale.  Thanks

The AUG rear stock/sling swivel pin will work on the MSAR stg556. But it will not fully stay in the stock like the MSAR pin. Due to the grooves in the AUG pin not being the same, it does lock into the stock but when you pull on the sling swivel, the pin will move a bit outward and not seat flush against the stock. I’ll have to pull mine out of the safe but think I just shimmed the gap with a washer.

Try v1tactical. They have the one with a sling loop on it. V1tactical.com

I have one. I have enough parts to last any two people a lifetime.

I'll send you a message.
