This light weight rail can help you reduce the weight of your airsoft gun or paintball marker. It is made out of strong and resilient plastic. And it is made to Picatinny specification. Replace your removable heavy metal steel Picatinny rail with our light-weight Picatinny rails. Our light-weight rails are available in different colors. Our light-weight Picatinny rails are available in pre-drilled version. However, non-drilled versions are available for your custom build. Because our plastic rail is strong and resilient, when you drill screw holes, be sure to secure this rail down with c-clamps. Airsoft3D build custom Picatinny rails to desired length and height. Contact us with what you need. WARNING: Although you can fasten this rail to your real firearm, this adapter is not intended for real firearms. We do not know if the firearm heat/recoil will or will not damage this rail and any accessories attached to it. Use this rail with real firearms at your own risk.
