TM MP5 NGRS Owners

Finally in the club ? In regards to the tight magazines, I've noticed the one it came with seems to need a bit more encouragement to fit but the others are fine.

Finally picked mine up from 'my guy' on Saturday, thought I'd provide my findings on accessory fitment:

-Real collapsible F stock required the rubber buffer removing then further metal milling under where it sat, my example also needed some material removing from the tops of each stock bar.  Unfortunately I can't provide further detail as I didn't witness the process.

-VFC lighted forend goes right on; the TM pin is a bit of a bugger to get through as things stand so I may ream out the hole in the handguard a fraction but it can be used as stock with some persuasion, nothing too serious.

-Magpul plastic handguard is tight af to get on and off where the rear of it goes around the round chamber area of the receiver, pin is fine though. I think I'll take some sandpaper to the inside of the handguard to make battery changes more reasonable in the safe zone.

Just my personal findings with my gun and accessories.

I have fitted the G&P handguard to mine and have found the same issue with the pin. However if I use the pin from my old TM mp5k it goes straight through.

Been a long time posting.

I still have a cycle issue, and wondering if anyone can help. Basically to begin with out the box (posted back in November 21 with issue and haven't used since until last night) few shots then misfire a few times, then fires fine continuing this issue off miss fires and fires on a mid cap mag. This is on single shot fire. On 3 round burst or full auto you don't notice it. Not to say it's not happening. Tried the banging the mid cap mags if it was that issue but continued. Cut to last night, hop adjusted (on tech guidance) and the problem disappeared managed to get about 3 mid caps emptied no dramas. Then it's started to occur again but you get about a couple misfires out of the 72round mid cap. (Slightly more on a mid cap).

Am I having a hop rubber issue or the actual hop unit itself?

Tech guy I know says potential hop rubber, but wanted to get some of your guys opinion as you've all had yours a while or know of anything similar.

 

[mightyjebus]

did the hop creep after the 3 mag dumps? sounds like it did. Try resetting the hop or alternatively wind the hop completely off as this should allow you to empty a magazine without issue and will show if the issue is mag feed, nozzle or hop unit/rubber related.

If you can empty magazines with the hop off then the nozzle and magazine are probably fine. You can also do a quick check on the nozzle by having a look inside the hop unit and firing the AEG. You should see the nozzle move back and forward with every shot (obviously without a mag inside and the AEG turned upside down).

It would probably be best to strip the hop unit out and rebuild if the nozzle and magazines are fine. If it's under warranty then send it back for the shop to do it.

Thank you for help, I will give that a go. I have purchased a new hop and nub so might as well put that in. I have respected tech guy so will go to them to do it.

Unfortunately it's way past warranty as I got this in November 21. (Also my second one as the first was faulty).

In all honesty I'm doing all this as I'm getting rid of it so I want it right for the next person.

Almost forgot to say cause the forum was down when I tried - got my Midwest Industries MP5TR in (pic + M-LOK) and it drops right on to my gun.  Really was expecting to have to get it milled underneath or inside the claw parts to fit, but no, very surprising.

So, I'm experiencing a battery red light issue too.

To preface I also use the Midwest industries handguard and a couple small 7.4v 20C Nuprol lipos. 

Skirmished today in semi chilly conditions between 10-15 degrees and played in shady woodland.

The gun would consistently go into safe mode with the red led flashing, swapping batteries would remedy the problem only for a few shots then go into flashing red led mode. Batteries are all balance charged and checked by the organisers for the health of the battery (all 90%> charge and healthy cells.) 

After doing some research during lunch mid game, the MOSFET manual states the batteries should be between 20°c - 30°c otherwise will sense low voltage or something and turn off the gun. 

The batteries and especially the steel handguard are very very cold to the touch. After leaving the batteries in my rear pocket and holding the steel handguard with bare hands remedied this problem for one round. Then back to going into safe mode, touching the handguard, cold as ice. 

Has anyone come across this problem, and have any advice for insulation, or maybe a different battery? really wanted this gun to be my reliable electric gun for winter with the nice Midwest industries handguard set up. 

Thoughts, feelings, condolences?

Yer had this problem on 2 ngrs mp5's with low rate discharge batteries (1000mah) getting really cold and causing that issue. Was solved with bigger batteries on cold days in winter. 2000mah+ worked fine in the freezing cold.

Had my preorder conformation come through, hurrah!

So question time:

Recommend me a battery to fit the Magpul handguard please?

Im probably going to be a heathen and get the drum mag and adapter unless I can find magazines.

I use this battery in my magpul handguard: https://eagle6.co.uk/shop/catalog/product/view/id/4693/s/vapextech-airsoft-7-4v-1300mah-25c-lipo-cranstock-battery-with-case-lp302-deans-version/

I would recommend switching the connectors of the battery to MR30's so you don't need to use the adapter as space is tight

FINALLY got my hands on an MP5 and four spare mags. Found a solution for mounting a scout light which works really well, and allows use of the original TM forend for maximum battery space. The claw mount is the wide TM version. You can mount an optic towards the back, with room to spare for a Surefire offset mount in front of it. 
 

The Scout light is long enough that shadowing isn’t an issue, but short enough that ambidextrous handling is still possible without having to change the forend and use a vertical grip. Pressure switch is just taped neatly on the top, as I like to shoot thumb over bore / C-clamp.

Got a night game coming up soon and can’t wait to try her out. The suppressor is the TM pro tracer, attached to the adapter which comes in the box with the MP5. Looks good enough for me.

That's really neat. I was looking for a way to mount a flashlight to my NGRS. Though I run a UH-1 on mine so may have to go another route as I'm lacking in rail space. Absolutely jealous of your spare mags!

I got 10 minutes out of mine at the weekend and then it made the expensive noise.

Disassembly today reveals a stripped piston, although gears are intact. Anyone know if this is proprietary to the MP5, or if it's common to the AK/G36 series? (doesn't look the same tbh)

Obvious follow up question - where to get one?

talk to Frank at fire-support. he can order from TM but it won't be quick (usual TM slowness)

Oh jeez. That's not good at all. Had you done anything to the gun? This is the first I've heard of the piston stripping. 

 

[Hatchet]

Yup, installed a new spring a while ago (Eagle6 M100 I think), so I accept this is probably down to me. It was literally just a spring change though. Nothing else got touched.

 

[TheFull9]

Bet you didn't even conduct the swap in a hermetic chamber to contain the TM dust ?

It's half a joke... I think we're in that early-adopter phase right now with people treading unknown ground with the platform.  It may be a one off of course, or maybe this design really doesn't like to be not-stock, or maybe it was a bad early batch, no way to say for sure.  Personally I'm only changing the externals on mine and the plan is for that to be all I do, at least for say 3-5 years, even then only in the event they release more variants, the user base grows and really good MOSFETs come out perhaps that are even better than the stock one.  My SOCOMs have a few little internal changes in 2 out of 3 (Deans swaps excluded), but I've left one dead stock and I'll bring one modded + the stock gun to any given game, which has worked nicely for many years I have to say.

 

[Hatchet]

It's fair. I fell into the "moar powaaaah!" trap. Also playing outdoors in a dusty environment and judging by the amount of crap, grit, etc on the innards it hasn't helped.

I guess by the time I get spares, there'll be mags back in stock.

Incidentally, there were a load over at Impulse101, which I was going to order but... eh, maybe not right now.
