I wonder if this could be related/connected to the issue I've been having. Also a heavy round count on mine. When I fire in semi, the BB getting chambered gets farted out of the barrel when the bcg returns into battery. PS. Love your content, very glad you're making stuff for the yama!
Without even pulling the trigger or releasing the hammer? Sounds like it's not being held in front of the air nozzle properly. I would check the hop, which is essentially the only thing holding the bb in place at that stage in the cycle.
@@bisterkding9249 I've replaced the hop rubber a few times hoping it would help. It did when I replaced the initial VFC blue rubber, but hasn't helped since. Currently running a ML MR hop for the contact patch. I've replaced the recoil rod, nozzle, nozzle return spring, and nozzle cross pin due to the NPAS putting a dent in it. I haven't replaced the recoil spring yet. I've been considering adding a small buffer to see if maybe the spring has weakened and is allowing bolt bounce, but slow-mo video didn't show any bounce...

In firearms, the behavior you are talking about is called "hammer follow" and it usually will not set off the next round because the bolt (being much more massive relative to the strength of the spring pushing on it) is moving much slower than the hammer would normally move and so it prevents the hammer from reaching full speed. The sear you point out is called a "safety sear" or an "auto sear" or a "connector". "Safety sear" comes from the fact that even in semiauto, it prevents the hammer from dropping until the round is fully in battery. Auto sear is obvious. "Connector" is because initially when the hammer gets re-cocked, the trigger doesn't release it even if still pulled (so the trigger is "disconnected") but when the "connector" is tripped, the trigger once again influences the hammer (lets it fall if the trigger is still pulled). I am curious about why an airsoft gun goes to all the trouble of having this mechanism. Isn't the BB actually propelled by an electric air pump? What does the hammer do?
Thanks for the info. The BB is actually propelled by the gas released from the magazine since these are gas blow back rifles (GBBR). Typical gases used are Propane, Polypropylene, C02, or compressed air with a regulator limiting output usually between 50 - 200 PSI. Auto Electric Guns (AEG) and some HPA, use a battery to activate a compression mechanism, piston, to compress the air behind the BB and propel it. The hammer in the GBBR, once dropped, hits a follower. The follower strikes the release valve on the magazine allowing the gas pressure to vent into the nozzle which will propel the BB and at the same time build up pressure within the nozzle to cycle the bolt.

@@ema1671 Thank you!!! These will be perfect for my TTI hop chambers that use set screws to stabilize the chamber against the frame!

Nobody cares
