Here is the first iteration of my new DMR upper for my MWS. Once I have the internals sorted I’ll probably convert it with a MK12 front end. At the moment it’s throwing out .36g bbs at 300 FPS with just the benefit of a longer barrel and some joule creep so getting a DMR FPS on .4g bbs shouldn’t be too much harder. I don’t really do the sniper thing enough to warrant a new gun so when an upper came up on the classifieds for a good price it was hard to pass up.

I ended up ordering this one: https://gpairsoft-uk.com/shop/en/53289-gp-dd-mk18-front-set-for-marui-mws-m4a1-gbb-black-gp-mws014a.html it’s good quality and fits well, but the flash hider thread is 14mm clockwise (not counter clockwise like everything else) So your choice of flash hiders is limited or you need to get a converter.

An AR wrench is really worth having when working on the MWS. Make sure you get a good one the cheep ones will break.

You can strip the magazines down and check the o rings and clean the follower and spring. I don’t do it every skirmish, unless it’s really muddy, usually every 6 months is more than enough. Otherwise a general wipe down and storing them with a squirt of green gas is all I do after most skirmishes.

looks like fun. What build are they for (vector?)???

My first one came from here with no problems so ordered my second from the same place. http://emperionstore.com/npas-kit-for-tokyo-marui-mws-gbb-ra-tech.html

I’m just about to start on doing a MK12 DMR upper for my MWS Having and I’m interested to hear peoples views on what inner barrels I should be considering. I’m aiming to get in the 450 FPS range with the gun locked to semi. At the moment my choices seem to be between (1) a 410mm long ORGA Lex 6.05mm barrel or (2) a 370mm long Prometheus 6.03mm barrel. Anyone had any experience with either? Which one will give me the best accuracy and FPS boost? I have the 250mm Prometheus in my current MK18 build and in that context it has been really good. I can also see that G&P do a 6.03, 410mm barrel, anyone used one or have any thoughts? I already have an npas on order and will be reaching out to buy a new brass nub tomorrow. Thanks in advance for any opinions.

I have used loads of WE green gas in my MWS. Its the same stuff as Nuprol 2.0 and it has always worked fine for me (providing the temperature was reasonable). If it’s colder then red gas (Nuprol 3) is good to keep you going.

Not sure exactly what you mean. If you are referring to consistency between shots then no, it makes no difference. The most consistent option is probably the stock valve as it has no moving parts that can get moved out of position (I haven’t had this problem with the MWS version of the NPAS, but on the WE version there are reports of the screw working loose during firing and thus the FPS changing.) If you mean between skirmishes or changes to different brands/types of gas, the NPAS will mean your rifle has much more consistent FPS as you can adjust it to take account of different gas pressures or ambient temperatures (it only takes 5 or 10 minutes with a chrono) so you can always be under site limits, but never so down on power that you can’t hit anyone beyond 10 metres.

You will always get some cool down with green gas it’s unavoidable. The problem is worse when the ambient temperature is lower. However 30 FPS seems a lot unless you are spamming the trigger. Have you down the green gas mod to your mags? If you have you may just be over filling them (do you see a lot of gas vapour come from the barrel and ejection port when firing?) This makes the cool down a lot worse. Alternatively try running red gas and using the NPAS to regulate FPS. Red gas is less susceptible to low ambient temperature. Final thought, consistency does get better with use as the silicone in the green gas penetrates and softens/swells the rubber bucking.

I’m running reliably at 350 FPS on green gas (Red gas if it’s very cold) with nothing more than a tight bore barrel and an NPAS. I could probably run higher, as there is still room to adjust the NPAS further, but I would need to lock it to semi before I tried and I don’t want to semi lock this gun. My next Airsoft project will be an MWS mk12 DMR build and I think I can easily get to 450 on mostly stock internals. One comment, on HPA it’s not necessary the FPS that causes problems, the potential for insane rates of fire can put a lot of stress on the internal parts. Keep the ROF realistic/sensible and at 350 FPS the stock parts should be fine.

And they are gone already....... Wow

Only 18 in stock as of 6:30. They won’t last long....

I have both the Taco’s and the Warrior ones. Both are fine and as made for real steel will easily hold an MWS mag. Personally I find the Taco’s to be slightly better, but it’s really marginal and not justified by the extra cost compared to the Warrior ones.

But does anyone know if the new p mags are any good??? Also that site doesn’t inspire confidence as the heading for the black mags describes them as some sort of fore grip for a Glock.. It might just be a proof reading error, but has anyone ordered form them before?

Good eyes!!! I didn't spot that.

what sight and magnifier is that? It looks really nice, much more compact than my vortex setup.

I have the MWS with the n-pas, and I just use a small jewellers screwdriver to stop it rotating when adjusting it. You may need to let it rotate a bit before you see one of the 'vents' in the Npas that you can put the screwdriver in to lock it up to stop it it rotating. Then just use the special tool in the nozzle to turn it.

Damn, Damn, Damn.... I was just talking about doing an MWS based MK12 DMR build. The Fire Support deal is really making it a test of willpower not to just start it now.... Really need to sell some stuff first to fund it.

Thanks guys, Not too worried about my ability to get through the day humping the kit (I’ve done worse) more about the fact that it may slow me down from a run to a nice sniper friendly jog. Also the extra two mag pouches fitted to my plate are quite bulky in confined places. Ill stick with 9 for now and see how it goes, easy enough to sling the extra mags and pouches in my bag and fit them to my plate during the day if I find I keep running out of ammo.

Thanks for the info. I have just put an order in. Out of curiosity how many mags do people run for skirmishing? Currently planning on 9 (6 on plate carrier, 2 on belt and one in the gun). I have the option of running 13 (10 on plate 2 on belt and one I the gun), but I’m concerned that the weight will start to limit my mobility.

Hi, New forum member here. Just wondering if any one had any info on any U.K. suppliers with MWS mags in stock, or any info on when they might be available? appreciate any info anyone might have.
