x3 Marui Glock mags for sale. £45 posted. I won’t split the listing, postage costs make it not worth the hassle. 
 

Used but all gas tight and working as they should. All 3 have the purple Laylax gas routers fitted. Mags have always been stored indoors and with gas in them. 
 

Technically these are 24 round Glock 22 mags. They fit in the TM 17 and 18. They DONT work in my Umarex Glock 19 or my TTI TP22, the nozzle gets stuck on the gas router stopping the slide from slamming forward. They do fit fine and work fine in my TM G26 (bit long obviously!) and my old TM G17 plus a mates G18. I couldn’t tell you if they work in other brands.
