I have the urge once again to get a Sig 522 swat but before I start looking seriously I need to know a few things.

Do these take AR 15 mags?
Is the barrel solid or shrouded?
Can the bird cage be removed to fit a Mod?
Are the polymer lowers reliable? eg: not prone to breakage at the pin points etc
Can an adjustable buffer tube type stock (AR) be fitted and still keep the folding facility?

Thanks folks

Do these take AR 15 mags? no
Is the barrel solid or shrouded? solid
Can the bird cage be removed to fit a Mod? yes
Are the polymer lowers reliable? eg: not prone to breakage at the pin points etc so far so good
Can an adjustable buffer tube type stock (AR) be fitted and still keep the folding facility? yes if you want to spend some dosh

Thanks Kenny

The SIG mags are the same as the (Ciener IIRC) AR mags. Black Dog mags work just fine.

You maybe right I was thinking of stannag style AR .223 mags I have no idea why

I have 22ARs built with both the M261 insert and with the Ciener/Aitchison insert and Black Dog mags for both. My Sig takes one of these types of mag and I'm pretty sure it's not the M261 version (though I could be wrong).

The lantac mags work well too :)

I’m working on getting Smith and Wesson 15/22 mags working with these rifles, I think it just needs some material removing from the top of the mags.

Will post back if I get it working.
