THE TM MWS thread

Hah yeh well we all know most upgrades are the complete opposite!!

 

[Jimmeh]

Just out of interest @Davegolf - do you have the Version A or Version B?

 

[Davegolf]

I have TYPE 'A', the TYPE 'B' is identical just even lighter.

It can only be a good thing! Faster cycle!

 

[Jimmeh]

I believe they made other refinements as well but I suspect they are quite subtle.

Damnit, @camden! I’m gonna have to sell some stuff in anticipation now ?

 

[Crazy_Crystal]

@camden I follow the reptile house, and yet I completely missed that. I am definitely looking forward to that. I have just bought my first mws, having had an aeg in L119a2 form. I am currently transfering some of the parts over and I'll take some photos once my order from Brownells comes in ?

I seriously love the short A2 form, it is as close to perfect for cqb that a 10 inch rifle can get, but that's just my opinion. I might be a bit of a fan ?

but I am definitely looking forward to seeing how that iur will turn out. ?

I wish they’d make a 416 kit as the other is stupidly priced.  Tempted by it though. Love the MUR uppers

Yes, I thought the upper looked good, I’d like one without a forward assist for my next MWS build lol

You could always just stop selling the ones you have ?

I build a gun, I (mostly) get bored with it, then sell it.

The only ones I haven’t are my Trigger’s Broom Vector and my SAI BLU

 

[Wo1f]

Trigger’s broom! I like that ?

 

[Immortal]

I need a John Wick conversion kit that changes me into John WIck aswell as my rif. :lol:

Does anyone have any issues with their bolt lock not locking??

I'm currently using green gas (ASG Ultrair) and it never seems to lock back though racking it back manually does lock it back.

I have tried unscrewing the buffer tube by one then two turns but no luck.

I did have a UAC bolt lock lever on it for a bit but i even change back to the stock one and the issue still persists.

Funny enough  i have found out that when the mag is near empty and only spluttering, the bolt lock seems to work fine???

Any fixes?

 

[Wo1f]

The mws is about the only gbbr I haven’t had a bolt lock issue with. 

If you’ve tried unscrewing the buffer to no avail, I’d consider removing and cleaning the ZET plate and the areas it makes contact with. It sounds like it’s not rising quick enough to catch the bolt when it’s rearward. 

If you have a heavier recoil buffer or spring, try that and see if it makes a difference. Should give you an indication that the ZET plate isn’t moving quick enough.

Hmm the ZET plate (assuming you mean the large-ish silver spanner looking thing) seems to move quite freely in the gun.

 

[Wo1f]

@Shizbazki you could try a lightweight ZET plate. They move quicker than the standard one. If it locks when there’s not much gas it definitely seems like a speed issue. 

Saying that... do you have an aftermarket mag catch? The mags could possibly be sitting low and not lifting the plate high enough. Try firing it with the mag pressed up in the magwell.

how many whole threads are between the buffer tube and the buffer retainer button?

I had a third party mag catch too, tried pressing up on the mag and then reinstalled the stock mag catch. No game.

The buffer tube is about 2 threads turned out (2 top threads and 3 valley threads).

Pressing the bolt release catch (on the bottom end) and firing a single shot does lock the bolt back which leads me to believe that the bolt catch is not rising up in time to catch the bolt.

 

[Shizbazki]

Ok in testing this and having stripped the gun down several times now.

I have tried:

Cleaning and regreasing the trigger mech

Tried both bolt catches (Stock and UAC)

Tried both magazine catches (Stock and UAC)

Tried pressing in and pulling out the mag with the mag locked in place

Firing in semi and full auto though sometimes on full auto it locks back

So far i am stumped as to why its not locking back

Out of curiousity i also installed a stock GHK M4 buffer and spring.

With the GHK spring and TM Buffer, no locking back

With TM Spring and GHK buffer lock back worked every single time though it does feel like theres some metal to metal contact at the fullest pull on the BCG so its not an ideal fix as i suspect at some point there's going to be too much wear and tear on the BCG.

I have cut the spring inside the TM Buffer to shorten its travel but this made no difference.

I have ordered a light weight bolt catch and see if that plays any game, hopefully it arrives tomorrow.

 

[Davegolf]

Sounds to me like your bolt is not travelling fully.

Firing in semi and full auto though sometimes on full auto it locks back

With TM Spring and GHK buffer lock back worked every single time 

Look at your floating valve and or nozzle for gas leak issues, or light striking on your gas exit valves, sounds like lack of power.
