Made in Texas! Not Chinese import and resell. Protects bullet tip from damage unlike others. Simple, cheap, lightweight, effective spare round holder. Screws are recessed. Easy to remove or install. Works with anything that is 308, 7.62x51 or 6.5 Creedmoor and has M-lok slots. Keymod may work but is untested. Other calibers may work but I haven't verified. Perfect for bolt action hunters. You can keep a couple of different types/grains of ammo quick within reach. Fitment is tight enough that the rounds won't fall out. 6.5 Creedmoor is a little tighter fit than 308. Comes with mounting hardware. Works with MDT Woox Magpul XLR KRG Bravo, Sig Cross and many more.
