Cross industries AR compatible .556/223 magazine

$40 each for a double mag consisting of two connectable 10 round magazines as shown - FIRM. They are $52 - 65 online plus tax and shipping. I have 4 of these available. Worked great in my BREN2 but I can't use my rifle until the conservatives get elected and sort through the dumpster fire they are inheriting. Shipping is extra (I'd guess $30 anywhere in Canada).

Unmatchable Materials

Designed to perform in the frigid north, our polymer is a new to market material that is specially formulated for cold weather impact resistance. Its unique properties allow virtually no change in mechanical properties from 73f/20c to -22f/-30c, whereas most polymer materials used for magazines have between .125-.25 the strength at -22f/-30c compared to room temperature. This gives us on average 3-8x better impact resistance than competitive materials at -22f/-30c. 

***Each set includes 2x 10-round pistol magazines and couplers***
