This is a great product! Full metal very strong, but light. The Rail its self is 5 inches long and fits great under my M16A2(would also work great under an M4) It has 3 points that you screw your bolts into 1 at each end and 1 in the middle. It is Rock Solid!! No give when tightened, the rail is going no where. This is a great product for adding a vertical grip or a flashlight/lazes to your M16/M4 for a low price. No need to go and buy a full RIS rail system look no further than this. Great product! Good price for low budget airsofters looking to add some goodies to their M16/M4. Cant be more happy.
