522 stock?

Why isn't anyone responding? I know someone has an answer for me. Can someone that owns a 522 help me out?

It's the same stock as a 556 Classic, but the 522 has only really just been in mass release for about 2 months, most of us haven't had time to become curious enough to change one out.

Thank you for replying.

I spoke with a guy from Double Diamond law enforcement supply the makers of the adapter for the 556 classic to a m4 style stock he informed me that he believes they are the same he is supposed to write me an e-mail and let me know for sure on monday and i will let you know

Thanks, I look foward to hearing more.

It would be sweet if that were the case. I have a 522 and hate the crappy stock that came with it.

Reply from double diamond "I did not have a chance to ask the SIG guys about the stock. I'll see
if I can find one in town and take some measurements".

So whats the verdict?

the last message i received from double diamond he told me that he is pretty sure they are the same but is not able to determine 100% if it will work . if you look at sigsauer.com at the pistols they have a 522 pistol with the same adapter so i think it will work but i am still waiting to hear back if you go to doublediamondsupply.com and send an email asking the same question it may speed up the process it will make them aware that more than one person is interested in their product for the 522

O.K.
I'll email them and see what they say.

Just got the word from sig that the pistol grip and the stock are identical from the 522 and the 556 so yes if you can get an adapter it will work double diamond has not released the adapter yet

Just received word from doublediamond. They are making a small batch of adapters and he will try putting one on a 522 asap. I'm going to order one as soon as they release them.

have you heard if this will fit the 522 yet i know they released them for sale just a few days ago :?:

The adapter from Double Diamond just arrived and I will test installation on a 522 as soon as the buffer tube gets here. Actually, maybe I'll just swap tomorrow since the 556 is going to get the new tube.

DoubleDiamond says it does.

Confirmed fit without issue. I will post a report in the Uppers, Lowers, Barrels and Parts section.
