Final build, for now, you know.

Anyone got a HAO bolt carrier? Whats your experience with them?

No modifications needed. - Would have mentioned that earlier if that was the case. The sealing of the ProWin mags in combination with the stock TM bolt carrier assembly is "better" - and does infact not interfere with the mechanism. Ergo: no upwards pressure. It does however put the aforementioned pressure on aftermarket parts like the G&P carrier because of the buldge. The feeding was flawless with all parts - stock and aftermarket - on any combo that I have tested so far by the way.

After all it was a slight difference in the construction of the nozzle-intake. The G&P - and most aftermarket nozzles - have a slight bulge in front of the hole where the gas goes in. That bulge hits the gasket rubber of the ProWin mags ever so slightly since they are couple of mm's taller than stock to seal better with the nozzle-intake. That's it.

So I ordered two more nozzle-housings, some springs - in case I break any during fitting - and am now the proud daddy of a fully functional, bolt-locking, smooth rocking G&P carrier assembly while using the 50rds ProWin mags! Easiest solution was the first I tried and it worked flawlessly: - G&P SAI forged bolt carrier - G&P nozzle return spring and nozzle internals (come stock with the complete carrier) - ProWin nozzle housing - Dynamic Precision springset - some oil In case anyone ever needs help, ask me.

Hope it indeed is "just" the MCX and not the S.P.E.A.R. - that would make me rob my own bank account :0).

Anyone know if this will be MCX or SPEAR?

Checked it, must have been either bad lighting or dirt.

The one I think you are refenrencing to is the OEM one ;). Silver = TM stock (bruised, scratched and hammer assist literally hammering itself) Gold = G&P (not even the colour/finish is scratched) Also: my stock hop-up unit was all wobbly and only held together with one O-ring. It is forced shut by the barrel adapter but it didn't seem good enough to me.

That is one hell of a voice :0). Concerning the ProWin mag + G&P bolt carrier situation: tried cutting down the gasket as this seems to be the reason after inspecting the height in comparison with the OEM gasket. Not a good idea without a proper rubber cutting knife. My cutter did not cut the material clean and I left it hardly touched after seeing that it wasn't gonna to the trick. Three different nozzle housings are on their way to me atm so I'm gonna report back if any of them did the trick. Attached are some photos of the parts for informational and entertaining purposes.

Who the bloody hell is skylar by the way?

That's what I was thinking, the gas gasket or gas router will most likely be causing my issue. - I have many tools at my disposal but not a single one to work on rubber in a remotly close to professional manner... so having had someone already cut down the gasket the right way or grind down the nozzle to fit could have told me what he did instead of me having to massacre an otherwise perfectly fine gasket tonight :0). Thanks @Davegolf for not telling me to drink water when I really want a gin 'n tonic.

Thanks for actually answering to the origimal question. That's what I assumed. Only glaring discrepancy I could find is the gasket on the ProWin being a tad bit taller. This is the place I'll start. Btw and fyi: The OEM MTR16 mags are 20 rds not 35. But even comparing Stanag OEM TM mags it is 15 rounds per mag more with lesser weight, more pooooweeer and so on. P.s.: If I was a ckever man I would simply buy G&P pmags which should fit like a glove. But I am not clever I am enthusiastic ^^.

Answering as many as I can. Let's go. Pros of the Mags: The ProWin EVO mags, hold 50 rds instead of 20 rds (MTR16) mags. They hold more and stronger gas than TM OEM mags without any modification. They are noticeably lighter compared to even the short 20 rds MTR16 mags. The gas-intake is on the back instead of the bottom of the mag which let's you reload faster in the heat of battle since you can simply let them fall instead of having to immediately stow them away. - Granted, this is not necessary and I rarely had to do it so far but at least I have less worries when I do that. Pros of the G&P bolt carrier: It is noticeably lighter than the OEM one which let's the carrier travel faster. It is reinforced in all the places where it should be i.e. the hammer assist is steel and does not deform over time. The stock one already deformed after only firing the first couple of hundred shots. - And it is continually deforming which will inevitably lead to a serious malfunction at some point in the future. Bolt catch assist? - Same thing, made out of steel instead of aluminium. The nozzle assembly's performance is more suited to fit international energy limits. Mine shoots consistent at 1.4 joules with the nozzle G&P ship their bolt carriers with compared to 0.98 joules with the OEM setup using the same bbs and the same gas. The carrier weight is fitted with rollers instead of being flat. This not only allows for a faster cycle but also for a more stable movement of the whole bolt carrier. The G&P nozzle is also fitted with harder springs all around. - Including but not limited to the nozzle return spring that loves to snap and makes for a sluggish bolt travel. The problem I described only occured with combining these two things. The bolt itself is working like a mad trailblazing rallye car in comparison to a stock road legal car. The mags themselves are a blessing all around. I hoped for other owners already having the same combo installed and being able to tell me where to file/dremel/grind some material to let thise parts do their magic. Sadly this - so far - seems to not be the case. But in all honesty: I cannot imagine that the majority of people in this forum are just and only slamming cosmetic pieces onto theirs to look all shiny flashy bling bling and call it a day after that. At least I have had high hopes for help. Will post some photos and - if I manage to pull it off - I am going to let you guys know first. Cheers.

May I humbly ask: Why have a forum this size only to stick to statements like "keep the gun as stock as possible"? - Isn't all this to exchange experience and help each make MWS-dreams come true? From what I read through 250 pages of MWS-glory-forum-posts a vast majority of people here are fitting theirs with everythibg they can find on the aftermarket. I want to run the ProWin mags as they are superior in design, performance and handling with a G&P bolt carrier which, again, is superior in every aspect. - My question therefor was if anyone can help with the combination as the carrier seems to hang up on a part of the mag. So if anyone can help it would be greatly appreciated- if not, that's alright, gonna figure it out on my own then. "Keep the gun stock" is not an answer to my question nor does it help. Thanks.
