SixtyNiner Posted June 17, 2013 Report Share Posted June 17, 2013 (edited) While fiddling about with my SOCOM recently I noticed an expected benefit of using a Magpul MIAD grip. The swappable backstrap means you only need to remove the pistol grip base to get access to the anti-reverse lever and unlock the gearbox after a jam. Edit: also useful for checking the pinion gear sits properly within the gearbox. Edited June 17, 2013 by SixtyNiner 4 Quote Link to post Share on other sites
GavM14 Posted June 18, 2013 Report Share Posted June 18, 2013 Hey Everyone, I notice a lack of information on other forums regarding the TM Recoil Series and decided to create a group on Facebook as a place to discuss experiences with this specific system. Please do a search on facebook for "Tokyo Marui Recoil Next Generation EBB Owner's Group". The primary focus will be on TM's SOPMOD, M4A1 SOCOM, G36, SCAR, etc. recoil series AEGs. Thank You!

christhesecond Posted June 18, 2013 Report Share Posted June 18, 2013 Upgraded my Tm 416 with a new spring to 345 Fps. All is working perfectly. I went to change my hop rubber today but the front receiver pin won't budge. Anyone else had this problem? Quote Link to post Share on other sites
VIPER-GR Posted June 18, 2013 Report Share Posted June 18, 2013 Give it some time and usage and magically the front pin will vanish in thin air........The first upgrade i did was replacing it. Quote Link to post Share on other sites

Curly68 Posted June 21, 2013 Report Share Posted June 21, 2013 Little bit of help and advice please. I would like to buy the Firefly hop rubber and nub but what combination would I need? I can find the soft rubber and hard nub for sale in the UK but that's about it! I use 0.25's if that is any use? Thanks Quote Link to post Share on other sites
PureSilver Posted June 21, 2013 Report Share Posted June 21, 2013 It's occurred to me that since I will be changing literally every component in my SOPMOD's gearbox, I might as well buy a new gearbox casing from Echigoya and sell the original, fully-working low-round-count gearbox as a complete unit. Does anyone know anyone who might be interested in such a thing? Or what it would be worth? Quote Link to post Share on other sites
arne71 Posted June 21, 2013 Report Share Posted June 21, 2013 A mate is converting a Recce rifle to a Diemaco. But there is a slight problem. He can`t remove the Daniel Defense rail from the receiver. He has removed all visable screws, but the rail is still stuck to the receiver. Any suggestions? Quote Link to post Share on other sites
Number5 Posted June 22, 2013 Report Share Posted June 22, 2013 Arne71, my suggestion to your mate is to leave the beautiful recce rifle as it is and if they must have a diemaco then sell the much more expensive recce and use the money to buy a sopmod/socom which will be 100 times easier to convert. The rails on recces are notoriously hard to get off. Quote Link to post Share on other sites

arne71 Posted June 24, 2013 Report Share Posted June 24, 2013 (edited) The gear box cases have been out of stock at Echigoya for about a year, so don`t count on them coming back in stock anytime soon. Echigoya is the only place I`ve seen them listed too. Classifieds might be the best option. That`s unless any of the Japanese members on this forum have other suggestions Edited June 24, 2013 by arne71 Quote Link to post Share on other sites
SixtyNiner Posted June 24, 2013 Report Share Posted June 24, 2013 Have you tried Eagle6? Even if it isn't llisted on their website I think it's worth emailing them. Quote Link to post Share on other sites
sacairsoftsn00py Posted June 24, 2013 Report Share Posted June 24, 2013 My m4 socom is still purring. Gearbox shell is in tact...thanks to the ARS sorbo pad. It has spent most of its life shooting just under 400 fps. Upgraded the gears, piston, nozzle, gears, bushings, barrel, and spring. I have the bearing spring guide as well but it puts me over the 400 fps limit most fields use. Add far as cosmetics go. It's still work in progress. Everything always is when you have too much stuff you want to build up. Lol Top: TM M4 recoil shock.

Zereck Posted June 24, 2013 Report Share Posted June 24, 2013 I have a Magic Box piston head for upgrade and I noticed that the O-ring is kinda loose on it(you can move it a bit but it jumps back to its place), at least compared to a normal V2 piston head. Is that normal? Quote Link to post Share on other sites
GingaNinga Posted June 24, 2013 Report Share Posted June 24, 2013 PureSilver, I think I can track you down an empty gearbox shell, or are you looking for a complete one? Either way, let me know what you need and I will track one down locally if you like. Quote Link to post Share on other sites
VIPER-GR Posted June 24, 2013 Report Share Posted June 24, 2013 GingaNinga i will be much obliged if u can find one for me also.... Quote Link to post Share on other sites
PureSilver Posted June 24, 2013 Report Share Posted June 24, 2013 PureSilver, I think I can track you down an empty gearbox shell, or are you looking for a complete one? Thanks for the offer, that's very kind! Fortunately I think I've managed to source a shell second-hand, so I'm probably going to build up my new gearbox inside it and sell my older gearbox as a complete unit, which means I won't need another 'box. If you're able to source me an ARS/Echigoya SURUS, then I'd be throwing money at you! 1 Quote Link to post Share on other sites
arne71 Posted June 30, 2013 Report Share Posted June 30, 2013 I´ve come across a guy making custom Diemaco rear sling mounts, unfortunately only for aeg and gbb. I use the enhanced Laylax lock rings on my rifles. Would it be considered "safe" to use a dremel on a gbb mount and attach it to my Marui ebb based Diemacos? Quote Link to post Share on other sites
PureSilver Posted June 30, 2013 Report Share Posted June 30, 2013 Yeah, I don't see how that could be a problem. A Dremel/power-drill with a sanding drum should make short work of any problems, but do make sure that you're buying one in the right size. GBB, AEG and Recoil Shock buffer tubes are all different sizes. Quote Link to post Share on other sites
Number5 Posted June 30, 2013 Report Share Posted June 30, 2013 Before the ARS, etc, versions where available I dremeled a gbbr ASAP to fit. No dramas, just don't take off too much. Quote Link to post Share on other sites
arne71 Posted July 1, 2013 Report Share Posted July 1, 2013 Thanks guys, sounds good! Will order two for gbb then. Hopefully it works out fine. Quote Link to post Share on other sites
blobface Posted July 1, 2013 Report Share Posted July 1, 2013 (edited) Yeah the ASAP for GBB definitely works.. although looking at it in hindsight perhaps the real one would have worked with even less modding, they're practically the same price . A file would do the job, or dremel if you got one as pointed out. (although, mine is front wired, so you'd have to take a little more off for the wires) Edited July 1, 2013 by blobface Quote Link to post Share on other sites
Hatchet Posted July 2, 2013 Report Share Posted July 2, 2013 (edited) That problem I mentioned earlier does appear to be shimming, at least in part. Now, having destroyed my piston, I understand a lot more about it than I thought I did before. I suspect the original issue, before I started messing around, was probably down to power transference and slightly poor shimming. The trigger contacts were tan all over with dirt, and when I cleaned this away I can actually see through it in parts, so I suspect that's part of it. That with the shimming meant that at random points during the day there wasn't enough power to fully turn the box and you effectively got the "semi lock" even in FA. Another issue I discovered was incorrect motor height adjustment. I hadn't realised that unlike a lot of other aegs, the motor height adjustment disk/plate (that sits between the grub screw and the motor and pushes the motor up when you adjust height) has a small square of plastic that sits underneath it. This has obviously come out at some point as I found it an stored it away when I found it without knowing what it was. Its absence meant that the plate sometimes fell into the hole at an angle and gave inconsistent/no/full adjustment, which would have been putting a lot of strain on the bevel gear. I may also have trapped the motor wires on occasion, causing similar issues. In my most recent attempt to resolve all this, I had managed to incorrectly shim the sector gear. This meant that it sat too high and the half teeth on it engaged with the piston when they shouldn't have. This sometimes pulled the piston back using the half teeth and then released it early into the full teeth, or possibly meant the full teeth released the piston correctly at full tension, but the half teeth picked it up as it was flying forward, before it had expanded properly. Do this for a few hundred revolutions and it wears down the teeth at the front end of the piston, then the next tooth, etc. Eventually the mangled piston jammed. I've now cleaned the contacts as best I can and reshimmed it. This time starting from the bevel gear. I hadn't understood that if the gear is shimmed too low you'll either have wobble/slipping or adjust the motor a really long way down and that if you set it too high the motor will either be pushing it down and generating resistance, or if it's really bad only be able to have part of the motor (pinion) gear touching the bevel gear. Previously I had just been trying to get little play using roughly equal spacing each side, and I had never actually put the pistol grip on and realised that you can still have play in "gearbox only" but have no play when the grip/motor is in place and correctly adjusted. I suspect in my case that being too tight combined with poor motor height adjustment due to missing plate was giving me a situation where only the top half of the pinion teeth were engaged *and* there was a lot of resistance. Not a good combination. Then I shimmed the sector gear due to the critical height relating to piston/pickup lever and did the spur gear last as of the two it's the most flexible in terms of position. So, contacts clean, gears shimmed (bevel, sector, spur) and PTFE round the cylinder head with the o-ring then put over the top of that, rather than the other way round. Hopefully when I replace the piston, regrease everything and put it back together it'll do a little better than before. It also explains why the problem manifest itself more (blowing fuses) with a higher powered spring - too much total resistance overall compared to standard spring, even though the rest of the setup wasn't great in both cases. I may actually revisit some of my older AEGs now just to see if I can improve them. - Edited to add - I also hadn't realised it was possible to view the pinion/bevel gear interaction with the gearbox closed up and the grip on through holes in the gearbox, which helped a lot in working out what was wrong and getting much closer to the correct motor height from the outset.
