The Delta 1.0 is a nerf scope that is designed to be printed in one part and work right off the printer.

the Delta 1.0 has no electronics and is a purly physical scope, so no magnifacation.It slides right onto nerf rails but sometimes doesnt click in because of a lower nub. 

the Delta 1.0 fits perfectly onto a larger blaster that is designed for mid/long range arsenal and is a perfect addition to your arsenal
