Lego technic Blowback Pistol
Sorry for the long break. I introduce to you 2-nd gen of my old technic blowback pistol. Technic pieces give extremely smooth blowback. Mechanism uses 1 shock absorber and only one rubber band.
Maximum capacity is 4-5 rbbs.
Rate of fire... I don't know but it's pretty easy to control.
Rate and comment :)
