This Picatinny adapter allows you to mount any phone (camera phone, SmartPhone, etc.) to a Picatinny rail. You attach this Picatinny Adapter to the back of a SmartPhone case or a SmartPhone itself--such as an Apple iPhone or a Google Android phone--using velcro, glue, epoxy, double-sided tape, or other fastening means. Then you can attach your phone to any Picatinny rail or Weaver rail. This adapter is perfect for your old SmartPhones that are collecting dust in the closet. Use your SmartPhone to shoot photos and videos. Or let your SmartPhone be your red dot scope. This adapter is the least expensive SmartPhone Picatinny bracket on the market. You can use it with any Android or iPhone reticle scope apps on the market, such as inteliSCOPE, iSights, iSightsPro, or Red Dot Sight. In addition to the adhesive, you will also need a #6-32x1-1/4" screw and a #6-32 nut to fasten this mount to Picatinny accessory rails. The adhesive, screw, and nut are not include, but can be easily sourced from your local hardware store (e.g. Home Depot, Lowes, etc.). WARNING: Some phones have battery cover on the back. The battery cover may come apart in extreme situations. It is your responsibility to determine the proper method of securing the SmartPhone. WARNING: Airsoft BB and paintball may damage your SmartPhone. Use your phone and this adapter in airsoft/paintball games at your own risk. WARNING: Although you can use your SmartPhone with this mount adapter on your real firearm, we have never tested it on a real gun before. We do not know if the firearm recoil will or will not damage the combination. Use it with real firearms at your own risk. Airsoft equipment and SmartPhones used for the illustration of this SmartPhone Picatinny Adapter are not included.
