Take the nozzle out of the BCG, clean out the insides and wipe it down with silicone oil and a little bit on the piston cup/sealing thingy. Over time it can get a little dry and hurt consistency

Fantastic post @KoheiN that would explain why the long contact patches hitting the orga barrel I had.

I’ve got a one off hop arm in mine. It runs fine on lighter ammo, just saying it has the ability to lift any BB. My Casv Mws is 310fps on a .20. I run that on .32-.36 have you tried the TNT TR bucking? Very similar to the maple leaf but squared like an R hop instead of pointed. What I think is happening in terms of the damaged maple leaf is it applies more pressure to the tip of the mound than the back because of where the end of the arm is. I tried using the wonder bucking which doesn’t have the tab as I initially thought it might be pushing the bucking forward onto the barrel lip, but that didn’t seem to fix it either so I abandoned it for the modify tan. For the FPS and the lift required for sub .36 bb’s there’s little if any gain to be had from a maple leaf. Particularly when it’s not completely drop in.

What are your specs? And FPS? I’m running 400 FPS on a .20 no idea on joules because I’ve not settled on a BB weight yet. I’ve tested it with .45’s and it will happily send them into orbit😂. Technically it’s an ER hop as the window has been enlarged. i had great success with the maple leaf, but the tip of the contact area seemed to get damaged after very little use. I figured it was cutting into the tip of the barrel window. I run them in WE GBBR’s though.

Yes a custom machined, R hopped barrel currently in my mk12 for initial testing. Id have posted results but there’s been gale force winds and none stop rain for the past 3 weeks. What I can tell you is it shoots further than my Kingdom of airsoft Real sword svd which has 30 more FPS.

Accuracy yes, but range is surely all hop pressure. If you’ve got a .32 flying straight and you increase the hop, you then don’t have a straight flight path, so you increase the weight of the BB to compensate. The only time I can see the range being effected is if you’re applying enough hop to almost jam the BB and reduce the FPS/power, which I’ve done before. That’s why R hops work so well. Large contact area but minimal intrusion into the barrel

On a standard TM recoil, .25 indoors and .28 outside I found to be the sweet spot. Or upgrade it and use .36’s😎

Because of how airsoft guns work, you can get more range by doing 2 things. Increase bb weight and hop accordingly (this works to a point. Too heavy and you won’t be able to impart enough energy to to BB, and heavier BB’s can increase joules) or increase the power, which is probably not possible if you’re at your FPS limit.

Remember you’ll get joule creep with heavier BB’s. I run .36’s, but I’d start with .30’s and see how you get on and what it chrono’s at

Using the super nub means you get to keep your original hop arm, which means you can use other nubs if you were to try long contact patch buckings like the TNT. With the strike arm you’re stuck with that. If you’re gonna stick to -.28 and under there’s not a great deal of point in changing anything internally. The nub will offer slight improvement, but massive improvement with .32+ BB’s. If you’ve already got the arm then you may as well use it though. PTS and Orga make one. I had to get mine from HK somewhere. Couldn’t find anything in the U.K. i had what I think was a madbull mk18 rail on one of mine. You could get it on, but I found it rotated a bit left or right because the alignment tabs are about 3mm too wide for the receiver. Whats your fps now? Standard barrel I believe is 6.08? So you’ll get an increase in your FPS. Personally I think if you’re staying to the same barrel length, just clean the one you have and use it. Unless you buy an EDGI or something like that, you’re probably not gonna notice a great deal of improvement. If you’re putting a longer barrel in to DMR it, a replacement makes more sense. I wouldnt put ASG ultrair in anything I own, but my CASV on propane (standard internally minus hop mods) is about 310. It depends on if you have a version 1 or version 2 nozzle.

When you thought it was Friday yesterday.. I’ve never been so disappointed 😭

Nuprol red is okay, but after using Guarder power up gas, I will stick to that for any time propane isn’t suitable. Seems to work like MAPP without the rancid smell

You playing at the weekend? If so, let us know how you get on with it. My aim for tomorrow is an 80m kill.

Despite the shit weather, DMR news will be here tomorrow night. I’ll just have to get wet 😂

Do it! visual representation of using an mws is game:

@Shizbazki Success! I've owned 3 GHK m4's (One of which i built from a forged receiver) and while they're nice, they just don't perform like the MWS does. If you're only gonna be using .28's or less, there's no real need to touch it internally. The nub makes a massive difference when using heavier BB's, which the standard one can't lift. I run my CASV mws (310fps) on .32-36 and my mk12 mws (400fps) on .36-.45's

i really hope that your comment was sincere.. You're one of the lucky ones that hasn't seen the fucking awful film.

Damn! Nice one!

Miles away from me sadly. North west.

Where in the U.K. are you located? If you’re not far, I could have a look at it and compare it to mine

@Shizbazki Definitely cycle speed by the sounds of it. Only other thing I can think of is have a look on the inside of the buffer tube and see if the bolt that holds the cap on hasn’t wound itself out and is stopping the buffer from going all of the way back in. I know the standard buffer tubes have the issue of the cap loosening over time. Would make sense as the spring on the FG buffer would go over the bolt, but the standard TM would hit it. You’ll need a LOOONG screwdriver though.

Is the GHK buffer heavier or shorter? To me, it seems like the BCG is going into the stock and then coming forward again before the ZET plate can catch it. If your catch surfaces are good, on the plate and BCG, I’d try stiffer springs/ heavier buffer. Have you got any duster gas to test?

@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?

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.
