DrFumbles Posted October 1 Share Posted October 1 On 29/09/2024 at 12:39, SSPKali said: First thing I would check is pull the bolt and charging handle out and check it and the inner of the receiver for sticking points, burrs and that it is suitably lubricated. While it is apart check the action of the “hammer” and sears that they move and reset smoothly. Some GT85 or similar aerosol teflon spray will help loosen things up. Then check how high the mag is sitting and if the mag gas router is catching on the underside of the nozzle or the bolt carrier. Thanks for this mate, Done all these checks and everything seemed ok...until I went to test it out. Clip attached because I'm still at a loss.

Wavey_Gravey Posted October 1 Share Posted October 1 Check your nozzle loading arm isn’t bent and try under filling your mags. Load them up to max then nock a few out, see if that helps. Link to comment Share on other sites More sharing options...
DrFumbles Posted October 1 Share Posted October 1 Thanks for the advice guys. I'm pretty sure it's the nozzle loading arm. The last time this happened though I had gas venting from the magazine. This time the bolt just doesn't travel forward as it should. Link to comment Share on other sites More sharing options...
Wavey_Gravey Posted October 1 Share Posted October 1 Yep that will be it. Heat it up a little and bend it back into shape, should get it working again. Link to comment Share on other sites More sharing options...

Kkylejjones Posted October 4 Share Posted October 4 What’s your thoughts, decided to move to GBBR and would never go back 🤣 was good out of the box put a few upgrades in it and it’s even better Impulse, Panama, ButcherBill and 1 other 4 Link to comment Share on other sites More sharing options...
Justjay1986 Posted October 5 Share Posted October 5 Jumping on this bandwagon with a noveske (I know technically it's no an mws lol) but boy do I love it. Upgraded the recoil buffer spring to a 120%, 130% nozzle return spring, g&p Ali buffer with one weight and a 50° flamingo bucking. Oh, don't forget the 3d printed flat hop nub! 😂 Ranging around the 65m mark nicely. Not that I play outdoors much but these things are a work of art.

ArranLH Posted October 20 Share Posted October 20 Is the SIXG and stock bucking still the GOAT or has it been knocked off the top spot?. I understand the SixG has been recommended all the time, but at the same time, it's been years since it had first came out. Link to comment Share on other sites More sharing options...
Impulse Posted October 20 Share Posted October 20 I found it didn't hop heavy enough BBs in my mk12 build, so I've moved over to Jaeger Precision Titan nub and a Flamingo hop rubber. That combination seems to work really well for me and outperforms the sixG + stock bucking setup at least in my MWSs. Link to comment Share on other sites More sharing options...
Hypokondrikern Posted Friday at 13:06 Share Posted Friday at 13:06 Back again after a detour with a GBLS and an AEG. It seems like all my builds return to the wishes of the MWS-system and its modularity. I also learnt something on my detour. A good replica doesn't equal a fun experience. Anyhow, my plan is now to build a DMR from a used / vintage MTR. I think it would be fun to build a 16 or 18 inch MWS DMR as those are really uncommon. I just wonder if someone could guide me to some inner barrel ideas and navigate what might be problems for the build. My limit is 1.7 joule with a 0.3 g while in Netherlands and 2 joule in Sweden (Berget). I see that a lot of people have gone with a 370 mm barrel for those limits. But I just wonder if one could go even longer? 400 - 450 mm without problems? Such a long barrel would fill the whole outer and make it easier to stabilize. It would probably lead to an outrageous muzzle velocity as well, which I hope could be tamed by a NPAS. However, am I right, when I say that it could also be more efficient? I imagine the gas getting more time to expand in a longer barrel thus using less gas. Correct me if I am wrong. Also, which one is the go to 45 degree selector atm? Thanks in advance for the insight!

I imagine the gas getting more time to expand in a longer barrel thus using less gas. Correct me if I am wrong. I'm in the UK and I have a DMR MWS built as a mk12 mod1 with the suppressor and everything (the Modelworks kit) and it's incredibly fun. Some people will argue that GBBRs don't make good DMR platforms because they're less consistent than AEG or HPA platforms and they're correct about that, however in realistic gameplay terms I don't see much difference in performance between my MWS DMR and my MTW DMR, outside of the depths of winter where the MWS struggles a bit. However, what you gain by doing a GBBR DMR is a hell of a lot of fun. Every time you squeeze the trigger it feels very satisfying! In mine I use a 510mm inner barrel because that's what reaches all the way through the outer barrel and comes out pretty much perfectly so it doesn't poke into the flash hider, but it comes right up to it. At the moment it's a Crazy Jet, but I'm going to swap it out for a Stalker barrel in the new year after I put one in my mk23 and it was amazing. You will need an NPAS to get the power where you want it. I have mine at about 1.8J (local limit is 1.88J) and it's lovely. The longer the barrel, the more it will joule creep, so while it does help you get to the power you need, you will need an NPAS to tame that power. I'm not sure it makes it any more efficient, because I think it basically just controls how much gas goes through the barrel to propel the BB and how much goes into the recoil, but I could be wrong about that. And for fire selectors, I just use the standard one, but modified. It's very easy to get it out and modify for semi-auto only, as you just need to dremel some of the material off. It's still a 3 stage selector, but instead of safe-semi-auto, mine is safe-semi-semi with the modification. Only picture I have at the moment, but it's got a nicer scope now, has a DBAL-A2 on the side and uses the short mags and a full m16 style stock that I'm going to swap out for a Magpul PRS stock in the new year when I also get the new inner barrel for it, as I won't be using it through the winter.

Hypokondrikern Posted Monday at 08:22 Share Posted Monday at 08:22 @Impulsethanks for the all info and insight! I have also been looking at the Stalker barrels. Happy to hear that they are of the advertised quality. Do you know if the flamingo rubber will work with said barrel and what NPAS do you use? btw. Good looking replica!

I have 3, but my DMR is my favourite one. And yes, the flamingo bucking does work with the Stalker barrels, as that is the combination I have in my pistols and will be sticking in my MWSs and m700s once I get around to it (not a high priority during winter). In terms of hop up configuration that I have in mine, I have the 60d Flamingo rubber in the DMR and the 50d Flamingo in the non-DMRs, all with a Jaeger Precision titan nub and it works very well and hops heavy BBs just fine. The NPAS I have at the moment is the RA-Tech one, but I want to swap over to the Jaeger Precision one at some point as the RA-Tech ones are fiddly to adjust, though it does work just fine. I don't have Stalker barrels in mine yet, but will be getting those in the new year as the combination has been really good in my pistols and I've really gone off Crazy Jet barrels.

martijn Posted Monday at 16:12 Share Posted Monday at 16:12 Hey all, i recently purchased a tm mk18 second hand with some upgrades like the 4uad bucking.

I live in the nether ands. thanks in advance! Link to comment Share on other sites More sharing options...
