It is not Chinese import and resale. 

The bullet tip is shielded from damage but still has a small window to see the tip. A simple, inexpensive, lightweight, and effective spare round holder. Screw holes are recessed. Easy to remove or install. It is compatible with 5.56,.223 and 300 Blackout. Uses one M-lok slot. The fitment is rather tight, so you won't have to worry about any rounds falling out. After some use it will break in. Keymod may work, but it is not yet tested. Other calibers may prove effective, however, I have yet to verify their effectiveness. Ideal for bolt action hunters. One can maintain several distinct types or grains of ammunition within reach. The fitment is sufficiently tight to prevent the rounds from falling out. It is supplied with the necessary mounting hardware. It works with the MDT Woox Magpul XLR KRG Bravo, Sig Cross, and many others. Made out of high temp carbon fiber polycarbonate.
