Smiller

Well, many days after starting, I've finally finished all 200 pages. Apart from figuring out that I really need to do more with my spare time, here are my main take homes from the thread:
The MWS in all its iterations is, as Snoop may say, the shiznit The MK18 version looks ace but the design is mental The third party support for the platform is huge @AlphaBearhates Nuprol The one constant upgrade that almost everyone agrees on as being performance enhancing and therefore an essential purchase, is the SixG brass nub Whenever retailers get any MWS's or TM original parts in stock (especially mags), they disappear rapidly, so act fast Angry Gun are shit, but they're not, sort of HAO Industries kits are incredible looking (416 and L119A2 🤤) but are jaw-droppingly expensive  @AlphaBearreally hates Nuprol Fire Support provide excellent service to the needy and cash-rich MWS brethren  Depending on barrel length, ammo weight, nub type, gas type, ambient conditions, lunar alignment and inside leg measurement, FPS ranges from 200 - 1,400 fps The green gas mag mod is not necessarily necessary @AlphaBearfrigging hates Nuprol Become familiar with Impulse101 and other Japanese sites and order well in advance of needing spare TM parts Nozzles, nozzle springs, TM hop rubbers and a decent armourer's wrench should be in everyone's tool/spares box This thread is an absolute goldmine of people willing to share information, admire other people's builds and welcoming other people in joining the growing number of MWS owners @AlphaBearabsolutely, positively hates Nuprol Thanks everyone. Looking forward to receiving the stock alert email telling me it's time to sell a kidney (or kid) as my MWS journey is about to begin.

I may do a comparison test in the future but I don't have anything except gameplay with the MTR-16: https://www.youtube.com/user/ucanhascheeseburger/videos?view_as=subscriber
 
The vast majority of my shots are close range (under 30 meters) but even for longer range shots across the field, I am easily hitting people from 50-60m away no problem.
 
Cutting nubs is very easy, you just take a sharp blade such as an X-ACTO knife for cutting cardboard boxes and cut straight downward on the front of the nub, being careful not to cut at an angle or make a messy cut. If you don't do this mod, your bucking won't be able to apply pressure evenly across the patch because the barrel gets in the way.
 
  
 
I haven't tried the TNT bucking with the brass nub, but I would imagine the brass nub would perform very well just about any flat or R Hop shaped bucking. Due to the concave shape of the nub, it will give the bucking contact patch more of a curved Maple Leaf-esque shape while a flat nub will apply a... well... flat contact shape over the BB. And due to the limited space where the nub can fit through in the hop up chamber, a slightly bigger nub won't make an insane amount of difference.
 
I've noticed that the most important factors are: 1) the nub must be very stiff and stable 2) the hop arm should be stable and not moving from side to side 3) the hop chamber should also be centered in the outer barrel, and 4) the contact patch must come down perfectly evenly over the barrel window after everything is assembled. #1 can mean anything from the brass SixG nub to the TNT flat nub (due to the length of the TNT nub it will require slightly more modification than others) to the Maple Leaf Omega Tensioner concave nub or even a Modify flat nub. #2 and #3 can be helped with a CNC hop chamber/arm combination lke the Laylax MWS hop chamber, or a small roll of teflon tape. #4 comes with a lot of patience and time.  
 
If you find that the Modify tan bucking wears down too often for your liking (it is an old design after all), I would highly recommend the Maple Leaf MR Hop 60 degree (if you're not using a lot of full auto) or the TNT TR Hop 50 or 60 degree, paired with a solid nub of your choice (assuming 350 FPS w/0.2g BBs). There will be a slight break in period of 300-500 rounds, but your bucking will last many thousands of shots easily.

Did you test the tnt with the brass nub (sixg)? What about best for running at 1 joule /350fps? Really interested in the results. You’re write up is fab by the way and really interesting. Giving me another combo to trial as the tan bucking just fails far too quickly.

If anybody is wondering about what bucking/nub combinations are good for the MWS, I have experience with four so far - the stock bucking, the Modify Tan + SixG brass nub, the Maple Leaf MR Hop (60 or 70 degree) + Maple Leaf Omega Tensioner/Modify flat nub, and the T-N.T. TR Hop bucking for GBB (60 degree) + Modify flat nub.   Stock Bucking + nub: +Accurate to roughly 40 meters, 50 meters on a good non-windy day and if the target's torso is fully exposed +Doesn't seem to get dirty too quickly, easy to clean +/-Decently durable, but you're limited to under 120 MPS/400 FPS -Can lift up to 0.30's only - nub is too weak -Feels smooth, not as grippy as Maple Leaf buckings   Modify Tan + SixG: +Very accurate out to 60 meters or so on 1.3 J, 0.30 - 0.36 G BB's (capable of lifting heavier BBs, up to 0.40, decent accuracy out to 70 meters - not sure about 0.45 or 0.48) +Drop in fit, no need to modify nub - the SixG nub is a good pairing with most buckings on the market +Works very well in cold weather -Not very durable -BBs often curve to either side at the end of travel, some lateral deviation observed -Limited to under 120 MPS/400 FPS, I would not go above 350 FPS in all honesty   Maple Leaf MR Hop + Maple Leaf Omega Tensioner: +INSANE range, approx. 70-80 meters accurately with 0.40g and heavier BBs @approx. 2.0 J and above  +Very grippy bucking, decently durable, makes a great seal with the nozzle +Consistent FPS +Lateral deviation is noticeably less than Modify Tan/SixG combo -Omega Tensioner needs to be cut at the front and needs to be perfectly aligned or else your gun will shoot way off -MR Hop bucking gets dirty quickly due to how grippy it is and is a pain to get squeaky clean (you'll need to strip and clean your bucking/barrel after every game day) -Very strange issue - has no trouble lazing BBs on semi-auto, but BBs will fall out of the barrel on full auto   T-N.T. TR Hop 60 degree + Modify Flat Nub OR T-N.T. standard flat nub: +Not as much range as MR Hop but even better consistency due to shape of patch, insanely accurate (it outranged most AEGs and I was able to score several cross-map kills) +Almost 0 lateral deviation +Doesn't get dirty as quickly, very easy to clean -Need to cut off front of nub in order to fit inside hop chamber -Needs teflon tape to seal better and prevent rotation of inner barrel inside hop chamber due to the bucking retaining edge being a bit thin - took more work to get this one right than the other combos       In close to medium range testing (placing shots at roughly 30-40 meters onto a large postcard sized target, about 8x10 inches), the Modify tan combination and the T-N.T. bucking are the most accurate, though at under 30 meters the difference is negligible across all the combinations I've tried and the stock bucking is more than adequate for hitting targets at this range. The main issue I faced with the stock nub and bucking was that it could not lift 0.30s very far unless I was shooting over 1.5 J. In addition, after a while of shooting I noticed a lot of horizontal deviation. I could literally see my BBs making sidespins down to their target and it was getting difficult to thread BBs through small openings.   However, past 100 feet is where the MR Hop and the T-N.T. buckings really shine. The MR Hop and the TNT buckings are on another level. The consistency of the T-N.T. from 30-60 meters is better than that of the MR Hop. The MR Hop is a little bit more "grippy." The T-N.T. seems to run cleaner. Both can send 0.40-0.45's out to 250 feet easily. The main issue with the Modify Tan bucking is that it's rated only at 50-60 degree and is not as durable as the TNT or Maple Leaf MR hop bucking. It also has more lateral deviation at long range than the MR Hop or the TNT bucking. There are numerous reports of people's Modify Tan buckings ripping from normal use. I don't see that happening anytime soon with my MR Hop bucking or my T-N.T. buckings.   Apologies for the long post. This is just my experience and results may vary from setup to setup.

I have a real one and it went on perfectly, no messing at all. Makes mag changes so much slicker and the obvious “i’m Now a proper operator feel”😬😉.  Never had any issues with bolt locking back etc.

Yep, I feel you, i'd got to the point where I was about to sack it too.  I had tried two different a.i. adapters, two madbull copies etc and in the end it was the bottle, I solved it by buying either the Coleman type or rothenberger plumbers propane - I was still fairly fed up as i'd bought a refill kit and a refillable Coleman type bottle along with £40 of calor's finest.  But once I'd binned that notion off she runs like a champ now.
I hope this is not teaching you to suck eggs but when you fill have you tried pressing that little bit harder and only fill in 1-2 second stab's. I do about 10-15 stab's per mag and if you weigh your mag before and after using a cheap eBay scale you can confirm it's filled right, for example mine weigh 473 grams gassed up with no bb's and green gas modded and 499 grams gassed,bombed up and magpul fitted. If you do that before a skirmish you know you can get away with one or two 'dodgy' fills and that you have 35 rounds on board i.e no guess work.
Hope this doesn't sound too daft but it's how I got it to work well for me.
 
 

Cheers fella, will give the file a go! 

Thanks fella. Will give it a go. 

Ive had this from a BB strike/malfunction. Found a ton of debris in the my trigger unit for some reason.

I *personally* use a spray lube for my trigger box. Nice and thin oil, and use a stronger trigger spring set as well to help the reset.

Also polishing the trigger box and the sides of the trigger itself will aid in reset.

I get the odd hang up but rather rare. Another squirt of silicone spray and im good to go.
