    COLORADO FRONT RANGE

    This was a well-executed modification to standard capacity 30rd mags that allowed me to couple two together for a 30 rd home defense rifle and still remain perfectly legal.

    I was worried that regular 10-round 5.56 Pmags might have issues in my wife’s new 300 BLK rifle. After some searching I came across CALEGALMAGS.COM. Ordered some 15/30s. We didn’t have to wait long, they shipped them quick. These folks took the time to replace the magazines in original packaging, modifications are clean with no obvious marks or epoxy. Took the mags to the range and they loaded to 15 no problem. Fed fine over shooting with no feed issues. I’ll be getting more. Thanks CALEGALMAGS.COM for taking care of us CO folks

    I’ve ordered many times for my Colorado 15 round legal magazines. Excellent products. Great quality assembly. Very very quick ship. Colorado legal! Order now, dont go to jail having the wrong mags.

    These mags load and shoot just like the big boys! Thanks for keeping me legal!
