Here is a review of the Airsoft RPG-26 "Aglen" by Airsoft-RUS. Based on the Sovier-made disposable anti-tank racket which is similar to the M72 LAW, this uses projectiles from TEK and TAG Innovations. They say that its simple construction ensures excellent reliability and durability. Something that you may want to consider as an anti-tank rocket launcher that you want to use in Milsim events.
