Got Wood? Posted March 17, 2019 Report Share Posted March 17, 2019 Forgive me if I’ve completely missed them all, but what with the growing popularity of 9MM AR platforms in the real steel world, why are we not seeing any of these in airsoft? One that fed of Glock mags would be a hot seller in my opinion? Link to post Share on other sites
Katotaka Posted March 18, 2019 Report Share Posted March 18, 2019 AFAIK Iron has one under development that seem to use TM mags Link to post Share on other sites
thatguy404 Posted March 18, 2019 Report Share Posted March 18, 2019 Essentially an MP9 wrapped up in a AR package. I can see issues with gas efficiency using glock mags, even if the bolt is tiny and lightweight. That said... I'd probably pick one up! Link to post Share on other sites
Got Wood? Posted March 18, 2019 Author Report Share Posted March 18, 2019 I reckon with the smaller profile ejection port you could happily have a bolt carrier group the size of a slide or less. Hardest part would be where to have the buffer so that you actually felt any of the workings at all, which is half the appeal. Link to post Share on other sites
hitmanNo2 Posted March 18, 2019 Report Share Posted March 18, 2019 It looks like it still needs a lot of work yet. Looks like a massively ridiculous bolt for a 9mm SMG. Stupidly large ejection port too. Just a prototype I guess. Link to post Share on other sites
thatguy404 Posted March 19, 2019 Report Share Posted March 19, 2019 Yeah that seems pretty excessive for what it is. However in real terms the 9mm bolt isn't much smaller at all. Though for airsoft's sake, surely a system more similar to the MP9's etc would work better? Link to post Share on other sites
Got Wood? Posted March 19, 2019 Author Report Share Posted March 19, 2019 Yeah it would work a lot better as a simple short bolt, that travelled as far as a slide, potentially with all the same internals as an GBB Glock, just a different blowback housing. Link to post Share on other sites
hitmanNo2 Posted March 19, 2019 Report Share Posted March 19, 2019 True, props for them for going with a seemingly RS sized bolt for realism but I just can't see it working out in terms of efficiency. Link to post Share on other sites
renegadecow Posted April 13, 2019 Report Share Posted April 13, 2019 An aluminum bolt should have as much mass as a zinc slide so it should perform similarly. But the felt recoil would be a lot less than the lighter glock carbine kits already out. Unless they make an all polymer receiver too. Link to post Share on other sites
Reppyboyo Posted April 13, 2019 Report Share Posted April 13, 2019 Came across the UDP-9 not long ago and gotta admit, I would buy a GBBR version. Looks cool as tits to me. Link to post Share on other sites
BigAl Posted April 14, 2019 Report Share Posted April 14, 2019 Bought time, KWA should have used Pistol Compatible mags for the Vector when they made that. Hopefully they'kk do a GBBR version of there TK45 and make it Glock Mag Compatible. Though if they do they probably use there own old Glock Mags, instead of the newer more common TM Spec ones.

sandstorm Posted April 14, 2019 Report Share Posted April 14, 2019 Kinda wish it wasn't such a hassle to figure a way to make an adapter for old KSC TMP mags in some GBBR AR, got a ton of the mags already. Gas rifle mags cost a leg, an arm and some dangly bits to get to decent amount. Link to post Share on other sites
Beeingmyself Posted April 14, 2019 Report Share Posted April 14, 2019 Just a silent though in the night But since Apple and the rest of the smartphone makers was told to make phones that use the same charger in order to save the world of unnecessary production how about somebody told the airsoftgun makers to use the same specs all over the line. Starting with the AR15 platform since it is the most common in all fra G&P AEG lowers fitting with KA AEG uppers Same goes for GBB and GBBR compatible magazines and body parts Think of the saving in materials alone in production.

Gas rifle mags cost a leg, an arm and some dangly bits to get to decent amount. I had converted a WE GBB M4 to take KWC C02 Uzi mags a year or two back in order to make a Colt DOE clone. So, it can be done but needs all sorts of modified internals to do it, a new loading nozzle, as well as magazine well adapters and feed ramp extensions. It probably wouldn't be too different to do the same thing for mp9 mags, so long as they physically fit in the mag well width wise. I have a build thread about it on the forums here somewhere, but either I can't find it, or it disappeared somehow. I do have a video of it on YouTube though. And it really does kick as much as it looks, the co2 really throws the bolt around. Link to post Share on other sites
MODDAN Posted May 2, 2019 Report Share Posted May 2, 2019 I remembered that build thread very well, Brigg. It made me want to do one myself. But at the time I lacked the skills and equipment necessary. And by the time I got a 3d-printer the thread was lost to the ages. Have you still got the pictures? I remember they where very detailed. Any chance of a 3d cad-file so one can make a similar SMG for oneself? Especially the custom nozzle and feed ramp, which keeps eluding me. The really tough part is the upper, which I guess is quite easy to come by in the U.S., but not so much in Europe. The handguards have already been made in CAD and is available for anyone to download:https://grabcad.com/library/m231-633-doe-handguard-1 But how did you make the front sight assembly? Did you buy a real parts kit, or was that also handmade? In any case, this made me want a KWC UZI for sure. Link to post Share on other sites
Brigg Posted May 3, 2019 Report Share Posted May 3, 2019 I might still have some of the pictures floating around but i may have lost them when my older laptop died. Back when i did that build, all of it was done entirely by trial and error, so even if i had saved any of the dimensions, they would be of very little use. I had no idea how to use CAD at the time so there were no cad files, everything was just milled manually, and tweaked till it worked. As far as the front sight assembly, that was all built by hand ( well, on a mini mill ), but i had found the schematics of it on google image search, from a thread on ar15.com iirc, so the dimensions for that should be available if you look through the image results. I have been meaning to make another one at some point though, And since i do now have a 3d printer, I would probably try printing a lot of the parts. Though some of them do have to be metal, like the feed ramp and loading nozzle arm i think would break pretty easy if they were PLA plastic. so they would have to be metal at least in some part., And the extended valve striker really has to be steel or it'll get mangled, even the aluminum ones i tried at first didnt survive long. If and when i get to try making a new one, my plan was to make a flat top upper version. And for that, the easiest thing to use would be the upper from a WE T91 since it has no deflecter or forward assist. So, its pretty likely that I'll be making another, i just dont know when, especially since i have an ongoing project at the moment. Link to post Share on other sites

SpecialWeaponsAndPlastic Posted May 4, 2019 Report Share Posted May 4, 2019 This thread is really excellent! Precisely what we where missing. I also did some more research on the subject and found these floating around the internet:https://i.pinimg.com/originals/0d/93/82/0d938284eeb787713b67bad634e6c715.jpg https://i.pinimg.com/originals/71/45/b4/7145b4d7ed1f35c2b6ae77ad9748325a.jpg Should be the schematics previously mentioned. La piece de resistance is, what appears to be, a full 3D CAD rendering of the front sight assembly made by someone on reddit:https://www.reddit.com/r/RetroAR/comments/b3f6wr/a_personal_projectexperiment_a_3d_model_of_the/?ref=share&ref_source=embed&utm_content=title&utm_medium=post_embed&utm_name=02f3247decc145dea7e3b18421e51360&utm_source=embedly&utm_term=b3f6wr Apparently, it is meant for printing via ShapeWays metal printing service in steel, which appears slightly overkill in my book for airsoft use. I've been wondering about the front handguard cap, it is supposed to be 1,8 inces in diameter. But could a 45mm freeze plug be a reasonable substitute? If so, all we need is a high quality resin 3d-printer and things are afoot. Link to post Share on other sites
Got Wood? Posted February 26, 2020 Author Report Share Posted February 26, 2020 ProWin have made this finally, currently at preorder. https://www.wgcshop.com/collections/pre-order/products/pro-win-ar9-conversion-kit-for-marui-m4-mws-gbbp£180 with 3 long magazines is actually very reasonable, especially with 2 nozzles as well. Maybe one day I’ll pick up an MWS and get this but it’s a lot of money all said and done. For now my £60 armourers works kit is a neat option. Link to post Share on other sites
