THE TM MWS thread

Well I am really hoping someone can help me with my MWS.

I have had this same issue with TWO of the same rifles in as many weeks. After a few hundred rounds, I have BBs falling out of the barrel on most follow-up shots. This is with hop up on FULL, which reduces the frequency a bit. If I lower the hop even a bit, BBs fall out after every shot.

The bucking is fine, but I replaced it with a Firefly and the problem still persists. It seems the nozzle pushes the BB too far and almost past the nub. Doesn't seem to happen when I manually charge the handle - only seems to happen after I fire a shot, so the force of the bolt / nozzle returning seems to then push BBs through. THIS IS ON GREEN GAS, which I'm told I should be able to use fine with this rifle.

The shop is getting back to me about the first rifle that started doing this - I'm hoping their technician may modify it to make it work properly, but I have to say, TWO rifles with the SAME problem in such a short period of time starts to have me questioning the reliability of these rifles.

Has ANYBODY experience ANYTHING like this before with their MWS?????

Any help would be very, very much appreciated.

Thank you

What bbs?

 
What bbs?


I only use Nuprol .25g

It takes quite a bit of force to push a BB all the way through the barrel, so the size of the BB doesn't seem to matter. It's when the bolt cycles when firing that I get the subsequent BB  pushed too far through that it only takes a tiny bit of force to have it drop from the barrel - but usually no force required - they just roll out regardless when firing.

Loosing my mind here!

 
Check you floating valve isn't stuck closed, this would cause the bolt to cycle back without firing the BB out the barrel and reload the next BB, subsequently pushing BBs out

Good suggestion - Unfortunately, not the cause of the issue in this case.

The first BB fires fine, it's the follow-up round that falls through once the bolt resets. It seems the nozzle is pushing the BB too far into the chamber so it makes its way past the hop.

I would definitely be looking at the nozzle / BCG closely

 
OMG! just upgraded my trigger box to the G&P adjustable one (flat trigger). Really delighted with the upgrade. if anyone is looking to upgrade the trigger box G&P adjustable one is the way to go!!!!

Please elaborate! I’m interested but just not sure it can make that much difference for the price.

well. from waht i can tell all the tiny parts in the trigger box are steel. upgrading all thsoe tiny parts of the trigger box to steel will set you back for quite a lot already if im right. also im in love with the idea of being able to adjust the trigger and ALSO the hammer (in case weather gets too hot i can increase the hammer strength to compensate the higher pressure of the gas from the magazine. I also have a soft spot for flat trigger lol

 
So, despite the new fill valves working like a charm at home, as soon as I skirmish today, they refuse to take propane properly, have to waste an incredible amount of propane to even fill the magazine enough to clear a mag. (Despite Green Gas mod). Will keep investigating, as both the Laylax valve and an original TM hi-capa valve were being temperamental.

They are also now refusing to take even regular GG bottles now....

Despite that, excellent performance, range and accuracy from the gun itself, just the effing magazines....

@RossF how are you getting on with the original TM Hi-Capa fill valves, they still taking propane well? Might ditch these laylax ones...

FILL VALVE O-RING works great for me... I have absolutely no problem and dont care about material of gas needle. Its cost me just under dollar for 5 pieces. Try it.

I have this ones, but its from my local shop...

I'll try an O-ring rebuild kit, I was under the impression that silent fill o-rings were bad? Well if they solve my issue fuck it because they'll save me so much money on propane.

That’s so strange. All I could think is it was temperature related if you were playing on a particularly hot day that maybe caused the valve to expand?

I haven’t taken mine to a skirmish yet since doing the mods - I tested each mag at home and all seemed good - will update once I’ve taken it to Airsoft Plantation in a couple weeks.

I thought silent fill with o-rings is best not to use as they prevent the displacement of regular air with propane?
