M4 pistol grip compatibility

[steverebo]

Are all m4 pistol grips compatible with all m4 aeg's?

I have a specna arms sa-07 edge and wondered if the ICS MTS M4/M16 Tactical Pistol Grip is compatible?

They are compatible but you may have to open up the screw holes in the top of the grip that connects to the gearbox slightly. As ics are slightly off spec to G&p and tm pattern.

Not quite as simple as that with ICS. You might find that the motor angle is off too with that particular grip.

Ask me how I know...

The above is me trying to find a grip to fit on to an ICS CXP-15 that has an MTS grip out of the box. Not even ICS' own newer stuff works (bottom,second from left) with the non-blowback ICS models which this grip was designed for. The motor angle inside the grip is very slightly different and specific to ICS - you could kill a (quite cheaply made) Specna Edge Bevel gear/pinion in no time at all.

You might be able to dremel the shit out of the insides to get things aligned better, but is it worth it?

No. The grip's crap anyway.

And I'm stuck with it. But the rest of the gun is awesome for my CQB shenanigans so it's a small compromise really.

OP - avoid that grip (or any ICS ones for that matter) and save yourself a lot of pain.

I’ve put G&p grips on ics with minimal modding, so I was speaking from my own experience.

The EBB lower gearboxes have different geometry to the non-ebb models. You also can't mix and match the Non-EBB and EBB uppers and lowers.

I have an ICS EBB model grip (UK1), and it will not fit any ICS Non-EBB models (of which I have three).

I have a Specna Edge too. I'll try and fit the MTR grip later. It'll be interesting to see if it fits.

Yeah I know the gearbox are different between the two ics versions… I have them both in my possession but never fitted one to the older non bb. So will be interested to see your results mate.

Some to some, not all to all, pretty clearly.  But that's not what you're really interested in.

Good call on binning of the Specna grip, that quick-drop base-plate is a solution to a problem that doesn't exist.

All I'll say is that one of these fine looking fellows fits my SA-EO2 Edge, with the motor angle seeming OK.  I don't remember having to file anything off to get a good engagement, although I may have done so without registering it as a significant event (airsoft, after all).

AliExpress, "Tactical M4 M16 AR15 Pistol Grip", doesn't appear to be brand-named in any way.

Ok, I've thrown a few on to test (note i didn't fit motors):

ICS MTR Grip - horrible fit - note the gap at the front and the angle even when tightened:

G&G Ergo grip (nearly identical to @Rogerborg's Aliexpress offering) - perfect fit with excellent grip/gearbox spacing, this was what was on the gun up till now.

Ares Ameoba Aliexpress knockoff - good fit, but will need a bit of spacing between the grip and gearbox (I use 3D printed shims).

ICS UK1 Grip - better than the MTR, but will need some dremelling at the front to get a flush fit with the rear receiver.

Hope that helps.

I would go for what Mr Borg suggested personally. Comfy enough and should be an easy drop-in fit.

I've found the tensioning screw in the base of the G&G Ergo grip a little weak.  Nothing thread lock wont cure but still annoying.
