Absolutely exceptional tutorial thank you what is more mindblowing is that you did this in 2016, many many years before anyone had any time on this platform to tinker and take these apart without losing half the springs in classic marui fashion, in 4K too another tip for getting it out is any openings you see, very gently use a flat head with masking tape over it as to not marr the reciever, further you can use a punch to ever so gently tap the housing from underneath where the firing pin sits you were ahead of your time man, thanks for your expertise

@@Dizzyfatpigeon kind words, thanks 🙏, would be nice to get back on the video band wagon at somepoint.

I needed to change the fire selector and mag release, perfect vid for me!

[@Solidsnake0208]

Lovely tan lines there Richard 😂 Thanks for putting this together!

This is a great video. I found however that if you open up the trigger guard you can get a decent punch behind the trigger much easier to do.

[@Eagle6Airsoft]

yup thats a great point, and actually how i do it in the workshop now. hopefully others notice this comment and it helps them out.

[@r4fken]

Great. Just a quick question I put in a new bolt stop (UAC) and after putting my selector back in its unusually stiff. What could cause this? Iv taken it out and had a brief inspection then lubed it and put back but that didnt fix it. Have you encountered this?

[@Reprobator]

At the 5 minute mark I could go no further on my MSW as the screw in mine is loctited in so hard even brand new screwdrivers with almost my whole bodyweight on them couldn't break the glue. So I've just got to hope I never need to replace a sear or something...

[@MothFaced]

Just found this video and I'm having a devil of a time getting the rear screw out (by the stock tube @ 5:00) and it feels like I'm just chewing up the screwhead - how does come out so easily here?

[@Eagle6Airsoft]

Get a nice ph1 I think screw driver, make sure it’s a good fit with a big handle. If that won’t move it apply heat. After striping as much plastic as you can from the area.

[@alexot9146]

You need a jis ph1 screwdriver it's different from a regular ph1. With a proper instrument it's easily removed.

[@FandyIPSC]

Is that sears already upgraded? What type do you use? Mine is just cracked.. Thank you

[@banana_ackchyual]

To relieve the most spring tension during long term storage, do I leave the fire selector on semi or full auto?

[@lemonjelly]

Thank you for doing this! Much appreciated!

[@notdavish]

Could the trigger be replaced by a real steel one?

[@Eagle6Airsoft]

David Rose don’t think so it’s still an airsoft gun inside the trigger box but I haven’t tried.

[@jimpgamingtv2158]

Is the bolt plate stop made of steel or aluminum

[@Eagle6Airsoft]

John Imperial it’s a coated steel or some kind of cast zinc that’s plated but not light enough for aluminium

[@kamppiruller98]

I have a problem with my TM gbb rifle. The trigger wont reset after firing on semi auto. I have to push the trigger forward to get it reset.. :/ do you have any idea how to fix it?? Thanks...

[@고유진-o7c]

Do you usually keep your gun coked while you're storing it?? It could make the disconnector spring weak and thus create problems.

[@willowrabbit]

it may be dirty, you may need a stronger trigger reset spring.

[@ENZO99141]

How did u fix it ? I am having the same problem

[@daedalus6533]

@@ENZO99141 Encountering the same issue, but it seems to be related to the hammer not resetting fully. Someone else on the other teardown of the trigger box that he fully tore down the trigger box & removed BB Debris, and it resolved his issue.

[@daedalus6533]

Going back to respond to this; trigger reset issue was related to bb debris being between the sears and causing reset failure. Clean the trigger box if you have the issue
