LEGO SCAR-H (Firing Pin blowback + Shell Ejection)

Mechanism heavily inspired by RealDualDesertEagle and Patrick Grant.
The mech can still be improved in various areas, especially in the trigger group. I am also testing out some more powerful rubber bands and it has been working a bit smoother.

[@leilamara3073]

i love how lego guns look more complex to build then actual guns edit: oh cool my most liked comment

[@aaaaaa-yg5yq]

Some mechanisms definitely get more complex (the design, not the tolerance/manufacturing part obviously). The main problems are that there is no propellant for the shooting/cycling; the slimmest parts are still pretty thick and in predetermined lengths so the firing mechanism can get really awkward; for the most part you are limited to rubber bands that always get in your way instead of having huge recoil springs, torsion springs, etc
