I concur with all the above comments. I have a largish scope on my Mk12 as I like the look, but it rarely goes beyond its lowest 3x setting. On the very few occasions it does go higher than 3x its on large open sites when I'm using it for spotting rather than for actually taking a shot. Glass quality will actually be much more important for you to ensure the scope is usable in all conditions (dark tints can make the picture too dark if it is overcast or if you want to use the sight at night dusk, and some cheap clear coatings can cause awful haloing or glare in bright sunlight). Reproduction optics can be a bit hit and miss in this regard so id suggest either being a RS sight from someone like Vortex or buying from Amazon (yeah I know) where a return will be easy if your airsoft repro turns out to be crap.

Yes the MRT and MWS uppers are interchangeable. So much so that I have a build with an MTR lower and MWS upper. Any accessory that will fit one will fit the other (assuming you have the correct rail fitted, i.e m-loc accessories obviously won’t fit if you have a keymod rail. Etc).

At higher joule limits heavier bb’s make more sense. A 2.5 joule DMR rifle will get much more benefit from firing .45g bbs at 345 FPS than a 1.3 joule full auto rifle will get from firing .45g bbs at 249 FPS. The original poster said he was working to joule limits and seemed unhappy that his longer barrel had joule crept up to 1.4 joules. Given heavier ammo also joule creeps (and the MWS joule creeps like crazy) he will likely get better range shooting something in the .32g - .36g range if trying to stay under 1.3j to be U.K. legal. If he is prepared to semi lock his gun and get up into 2j + territory then heavier bbs make absolute sense, but then the longer barrel wouldn’t be an issue.

The only reason to increase the barrel length on the MWS is to increase the energy transferred to the BB thus upping the FPS. If you don’t want to do this then a longer inner barrel doesn’t offer any benefit. Just as a thought in the U.K. most DMRs will be semi locked so they can make use of the higher energy limits allowed by most sites for semi locked guns. If this isn’t your bag then you are really just tuning your regular gun. Just a note on BB weight, if you are not trying to joule creep and are measuring muzzle energy properly .4g + bbs will be on the heavy side to get the best out of the MWS .32 - .36g will give the best performance in my experience (there is mountains of info on this in the MWS thread.

At £300 i'll order one the day they are available in the uk. Any more than that and i'll wait for the used ones to turn up, which is bound to happen once a few of them get played with and the disappointed purchasers realise a £400 pistol doesn't immediately turn you into John Wick.

If I can see properly and that is $400 USD then by the time it reaches the U.K. it is going to be at least £300 (possibly more). That is a pretty strong price for a GBB pistol. I hope I’m wrong and they come in cheaper. I’d be prepared to pay £300 but any more and I’ll be passing.

I love gas. The sense of immersion is so much better than with AEG as they just feel like sewing machines to me now. Even the ones with recoil aren’t as satisfying as a good GBBR. That said for a regular skirmish (and depending on how you play) you may find yourself at a disadvantage compared to the AEG wielding masses in terms of putting down weight of fire. To my mind the best two GBBRs available right now are the Marui MWS if the M4 platform is your thing or the WE Apache if you are an Mp5 kind of guy. But then I may be biased as I own more than one of both types.

I’m not a brand snob, all I want is a GBBR AK with reasonably priced reasonably easy to get hold of mags. At the moment neither GHK or Marui are able to manage this so I’ll stick to my MWS M4.

Yes this is absolutely normal after enough rounds. red gas will just speed up the process.

Just picked up this little beauty (WE GBBR) that I can run as a Mp5k or Mp5 PDW. This now means I can run every MP5 variant as a WE GBBR….

Does the stock fitment mean that folding stocks will also require a new lower receiver? If that is the case it seems remarkably short sighted…

I normally carry anywhere between 5 (3 in the plate, 1 on a belt and 1 in the gun) all the way up to 17 (8 on PC, 2 on belt, one in gun and 6 in an assault pack) depending on what I am doing. I do lean towards the lower end of the scale most of the time with 7 being the norm. I don't think I will ever carry all of the magazines I own.

Oops, you just reminded me I have another 8 mags in a PC that I used at the last skirmish that I had forgotten about. ?‍♂️?‍♂️?‍♂️

Ouch!! That would bloody hurt, especially on a tiled floor!!!

I try not to think about it…. In fairness I only bought one set of mags when I bought my first new MWS. The others came as part of used packages when I bought my other MWS. My main reason for keeping them is I figure If I ever sell up I’ll get more for each MWS if it comes with a usable amount of mags….. Well that’s my excuse and I’m sticking to it…

Internet forum: How many mags do I need for my MWS? Me: Ummmmm…. Yes!

How new is the mag? I find the MWS mags all start off a bit stiff at first when speed loading. The extra mechanical advantage of the loading rod really helps for new mags.

Taking that part of the mag apart is easy, just remover the two hex head screws from the base plate and that’s it. Be careful though there is a small plastic piece at the base plate end of the feed spring that likes to shoot it’s self into orbit if you are not careful. while you have it apart check the bb follower for imperfections. I have had one mag with this problem and it had a small amount of extra plastic on the bb follower I had to carefully polish off. Be aware putting the feed spring back in is a PITA. The aforementioned small plastic ‘plug’ seems desperate to ping across the room and get lost behind the sofa of embed it’s self in your eyeball. I found a bbq skewer helpful to feed the spring on to before trying to jam it back in the bb channel. Have fun!!!!!

No personal experience with firefly hop rubbers, but in general soft hop rubbers perform really well in DMRs they just have a relatively short life span. The modify tan itself is very soft, this is one of the reasons it is so ‘grippy’ and works so well. I often use a 50 degree maple leaf in my DMR, with great results, but a rubber will only last a handful of game days. I don’t spout on about it because I don’t feel it’s right to recommend something with such a short working life. One of the reasons I went to Maple leafs in my DMR was that the modify tans don’t last that long at DMR FPS and a while ago they became very hard to source. The availability seems to have improved now, but they are still a couple of quid a rubber more than the maple leaf which really adds up especially when l have to pay shipping on top when the MLs are available locally.

That setup would certainly work and I have run similar before. Personally I prefer the deception rubber for consistency, and as I will always be down tuning the FPS with my NPAs to get to site requirements I'm not bothered that it requires slightly more barrel intrusion to hop any given weight of BB.

I have Crazy Jets in two of my longer barrel builds and have found them to be pretty good, but If you use them you really need to pair them with a maple leaf rubber and omega hop nub to get the best out of them, and the hop rubber needs a millimetre taken off the tab with a razor blade so it seats in the hop unit properly. If you use the brass nub and modify tan rubber which is well regarded in these parts then the Crazy Jet will be mediocre at best and there are several barrels that feature in these pages that are a better bet.

So I haven’t sold my NGRS to get an MWS as I still have it as a safety net, but I can’t remember the last time I used it in anger. I have a number of MWS and they are so reliable all year round that the NGRS doesn’t get a look in. I actually started a thread about selling it and it will be on the chopping block as soon as I can dig out the box. That being said I personally would never go to a skirmish without a backup rifle. I’m time poor so don’t get to go to as many games as I would like so it would suck if a mechanical failure ended my day early. But that is as likely with electric as gas.

You know you could just keep one. It would probably be cheeper.....

In My I have had a WE Mp7 for a while and it has been pretty reliable despite having a lot of rounds through it. I'm not really sure where the 'they break a lot' vibe has come from, but in my experience they are just as durable as the Marui, and when they do break something (and all full auto GBBRs will break somthing eventually) the parts support is much better. The bits that tends to wear first are the bolt catch and the trigger sears as they are made of finest pot metal. Personally I'd replace with stock parts. RATECH steel bits are available, but require time and effort and some careful filing to get to work nicely and given the cost aren't worth the effort. In my opinion the reason they come up for sale so often is they shoot like crap out of the box, nothing that isn't too difficult to fix, but it needs some work to shoot well. A couple of things to look at: 1. Out of the box they are covered in tones of shipping grease that needs to come off. Clean them out with some engine degreaser and then re-grease with a light spray of silicone over the bolt and a smear of grease on the runners and the gas efficiency will be much better (yes you still get some cool down, but you will at least get through the whole mag). 2. Before you judge it too harshly put 1000 or so gentle rounds through it (semi or short bursts) and then clean and re-grease it. The parts need a while to lap together so they run smoothly over each other. 3. The hop is totally rubbish as the hop arm fowls on the hop window in the inner barrel so you can't add much hop. You need to either file the bit of the arm thinner or enlarge the hop window (or some combination of both) to be able to apply more hop. I haven't done it on mine, but a crazy jet inner barrel may also fix the issue as they generally have a larger hop window.

I completely agree with this sentiment. I got an MTR used so I could use the ambi lower on my competition gun. Good job I got a good second hand price as the only bits that survived were the lower itself the buffer tube, charging handle and the silver bolt (which makes no difference to me). All the remaining parts were replaced. I even went as far as using a standard MWS upper receiver so I could still have a functioning forward assist. I used the spare MWS lower and MTR upper to make a, 8” PDW build where the forward assist deletion makes much more sense for concealed carry.
