We'll need OP conformation on fit.
The smoky .22LR are Black Dog Machine XForm mags. The gray one is similar but slight difference in feed lips but if they all worked in the same gun they're good to go. Their Site's old listing was Mag X fits and then lists the guns. Now you Search gun model and it takes you to the right mags. This killed the cross fit listing.
At the Mfr site there's some notes on model/Gen and fit, different feed lips and notes like some won't hold open bolt on CMMG, Gen III won't work in SIG522, ect... potential buyers can eyeball them for comparison.
