TX22 +2 round Magazine Extension (2 Pack!)

Yep, you read correctly. These are made from carbon fiber AND polycarbonate (the same polymer used in bullet proof glass). Here at White Mountain Manufacturing we specialize in advanced polymer additive manufacturing and we don't settle for anything but the best. With our carbon fiber reinforced copolymer, these won't melt if you leave them in your car on a hot summer day or break down from UV when you go outdoors or dissolve from any of the oils and solvents used on your guns.

To install, simply remove your old magazine baseplate and slide on the new one

Made proudly in-house in Nashua, New Hampshire.
