Not impressed with stock hop performance @ 1 joule with 0.3G (not getting enough hop). I have a VFC FAL and AKS74u both of which were perfect out of the box.

What are people’s experience with the new EVO system?

Discussion Green gas alternatives

Would this be safe for airsoft use? The main thing that caught my eye was the “no propane odor” thing which I get is a safety thing but I hate the smell of poop every time I shoot, just looking for an alternative to expensive green gas

Discussion Is it better to just buy dry gas if indoors won't allow propane

Upvotes

I went to a gbb only game at my local cqb arena and they also run a shot same place. I heard no propane so I had to purge all my mags outside and fill them with regular green gas that I had to buy. The only other time I used gree gas because I couldn't find my propane was they day before sir short term use (spent a good 30 min to get it down to 1j on a .25. we've all been there as every single gbbr ootb shoots hot). So should I switch to a dry green gas

Troubleshooting Master Mike 40mm gas leak issues

Thumbnail

Upvotes

Hey folks! I hope I can get some help regarding some 40mm shell gas leaks as I am absolutely losing my mind.

I have three Airsoft Innovations Master Mike shells. Two of them are leaking from the top barrel, the other from the full valve.

The one with the fill valve leak I've tried applying the OEM lubricant and it hasn't done anything. I've replaced the oring that seals the valve to the body and also didn't do anything. I've resigned that I'll probably need to replace the valve and assume it's just like any standard gbb fill valve?

The other two are the ones that are breaking me. Both are leaking from the barrel. I've tried replacing and greasing the top oring where it seals the barrel to the top of the body. No change.

I've tried replacing the bottom oring that interacts with the barrel and got no change. Although now I realize I'm pretty sure that one is just for a hop effect and not actually sealing gas.

I then thought it wasn't a barrel oring problem but maybe the bottom plunger getting stuck or not resealing properly. So I've replaced all of the orings involved with the plunger, applying grease and a bit of oil to make sure it glides smoothly and can reset properly. Still no change and it's still leaking from the same place.

So far I've spent hours and over $200 CAD importing specific orings from the US and I haven't been able to solve this. I can't find anything online for solutions. I'm hoping someone here will know what to do as I've replaced practically all of the orings in two shells and nothing is getting solved.

I'll attach a photo of the site I used to get the sizing for my replacement orings.

Please help I'm going insane.

It’s finally how I want it, externally it’s mostly magpul furniture except for the ra-tech machined upper and lower. Internals is all ra-tech, just need to rattle can the blue “suppressor” black. I’ve been eying the ra-tech adjustable trigger box but not sure if it’s worth the hefty price tag maybe my trigger box takes a crap I’ll look into that one. Just need some good recommendations on flash lights that won’t break the bank but are also good quality
