Was finally able to pick up the A4 with another couple of spare mags

Home safe with the baby. About to perform surgery.

surgery done… just swapped the spring.

just an FYI, the bore of the piston is on the smaller side… I’ve been using zci sp100 springs as they are within .5mm in diameter bigger than stock. I run a sub 350 fps setup. My other mp5’s shoot between 275-285 FPS with .25g bbs (hop already set). Supposedly eagle6 springs work well with the gun but I only have their sp90 springs. 

 

[PigDoggy]

So I rummaged through the box and found a piece of plastic that I had no idea what it’s for. Upon inspection, I realized that it was a tool for pulling the stock pin out! Pretty neat inclusion….

I’m sure it’s all in the manual but meh. ?

Before I utterly f*ck the ECU in my MP5, does this layout for the connectors look correct? Singled out pin on the MR30 for positive to the vertical pin on the deans? I'm like 99.9% sure but want to check ?

The ngrs has an mr30 connector?

That's interesting and bizarre.

You want a decent sized bit and good wattage for these types of connectors, plug a spare connector into the other end that you are soldering incase you overheat it.

 

[Jacob Wright]

Yeah comes wired to an MR30 as standard - I’m assuming to allow the ECU to monitor the battery level?

Gave up making a connector due to my shite soldering, the Eagle 6 one has been spot on.

hi guys, the mp5 has been out for a while now so was just wondering what are people's favourite options with regards to top rails and handrails for more mounting options.. thanks  

 

[BigStew]

MR30 are a MotherF*$ker to solder. That is all!

The biggest concern with railed handguards is the battery compartment. 
 

not so much of an issue with the mp5a4 as it’s wired to the back….the sd6 currently only has the option of running the wii tech b&t type railed handguard.

the a5 will be able to use Midwest industries handguards but you’ll have to find nunChuck batteries that fit it. Other railed handguards have the same issue….not a concern id you’re willing to run a peq box for battery storage.

I personally just run the Marui mp5 scope mounts as it’s  Marui spec. People have ran Midwest industries extended top rail as well as the Laylax full length top rail.

the laylax top rail will make the mp5 chunky. I opted to chop it to allow for a front flip and rear flip up sights (middle mp5 in the attached pic).

Cyma MP5/G3 claw mount is rock solid. Cyma extended m-lok didn't stay in place due recoil so that was wasted 35 quid for me personally.

None of the aftermarket handguards are generous regarding battery space but for me Midwest repro (Wii-Tech) offered absolute fuck all so I sold it and I bought a Magpul SL instead. More importantly you should solder your battery to mr30 because you save a lot of space not using that tamiya to mr30 adaptor.

Don't need another wire to monitor battery voltage, maybe it's for trigger positive

 

[rj1986]

I might just be special, but I've manged to squeeze a nunchuck 7.2 lipo (with mini tamiya) into a WiiTech repro handguard. It's tricky but doable - but yes, i admit it would be better with a direct to MR30. I run the cables above the barrel, and the battery at 4 and 8 o'clock. Long Mlok at 6 o'clock with a vert grip and small light.

 

[PigDoggy]

Cause someone had to do it.

Magpul stock and handguard along with the M-SL type lower from Japan. Front and rear flip up sights are Magpul MBUS Pro’s. Magpul M-Lok Cantilever mount for the Scout light. Have a rear QD sling pin from HKparts.
 

PTS muzzle and Laylax HK Mode-2 silencer towards the pointy end.

chopped down ZCI 100 spring installed. ~325 FPS with .20g bbs/ ~275 FPS with .25g bbs. All else are standard parts.

Per the description from impulse101, no mods were required to install the lower. However, on my unit….I opted to sand down less than 0.5mm off of the left side selector lever to create better clearance. The selector would have probably functioned fine without shaving some material down.

I ordered another one for one of my SD6’s. I’ll see how that install goes.

Moved on from having the mr30 to deans adapter…decided to re-wire my batteries with mr30’s so it plugged straight into the mp5. Deans plugs was definitely easier but I wouldn’t say it was difficult to solder the mr30’s into place. 
 

Ended up having to make a deans to mr30 adapter for the charger as well.

[Sewdhull]

I am puzzled, why didn't you put a deans on the rif instead of making 5 new connections?

It's up to you ofcourse, but the mr30 is inferior to the dean's in everyway.

 

[EDcase]

Yeah, just chop off the mr30's and replace with Deans. (One wire at a time of course ?)

More connectors = wasted power and less space.

 

[PigDoggy]

There’s 3 cables coming from the gearbox that’s soldered into the mr30 connector. I don’t want to touch that for a few reasons. One, is that there won’t be any place for the third wire as the deans plugs only has 2 leads. Another is that the wires are on the shorter side….I don’t want to go through the process of tearing into the gun to re-wire everything (not to mention the other NGRS mp5’s I own). Third, mr30 should be adequate for the job. The Marui 7.4v 1500mah 35c lipo utilizes the mr30 connector. I’m only running a 7.4v 1300mah 20c lipo.

I was running the mr30 to deans adapter for my mp5a5, mp5a4, and mp5 sd6. I just pulled them out of the guns so I can now run the batteries that I soldered mr30’s on.

Even if I was running the mr30 to deans adapter and still using the deans plugged battery, the battery is still essentially connected via the mr30 connector.

The other 7.4v 1300mah batteries that I was using with the deans connectors on them probably won’t be used for the mp5 anymore unless I end up pulling an mr30 to deans adapter from my box. They’ll be used for the 74mn, M4’s, Scar’s, and MK46 when I switch over to them.

Yeah, just chop off the mr30's and replace with Deans. (One wire at a time of course ?)

More connectors = wasted power and less space.

Less wires. Also neater.

[EDcase]

Yep, totally up to you.  (I thought the gun was wired to Deans)

Doesn't make much sense that there are 3 wires going into the mr30 which then connects to only 2 wires on the battery.  Two wires must be going to one.  (Likely a sensor wire for a MOSFET)

Yeah. I’m not sure. The mr30 has three leads on it. Maybe a low voltage cut off built into the Marui trigger system. The Marui 7.4v 1500mah 35c lipo using the mr30 also has 3 wires coming out of it which I assume is for balance charging.

on a 7.4v lipo, the connector for balance charging is also the same connector you plug a low voltage monitor/alarm into (when you’re running lipos on RC’s) so you don’t run the batteries too low.
