Bolt stop: first photo is loaded magazine, second photo is empty magazine.
Firing demonstration: ambidextrous trigger, trigger response, and bolt stop function illustrated. Recoil shock is not clearly demonstrated, but I can tell you that it is as Dizzy described previously – not nearly a GBBR perceived recoil., but way much more than your standard AEG (even more than most “blowback” AEG’s).
Chrono results on 5 shots: 299.3 – 300.9 FPS on Tamashi 0.20g Biodegradable. Very consistent!
