Hey, new to the forums! Just recently got my new KWA KM4 M4a1 and have some external upgrading questions. So why not ask kwa forums?

After researching some threads here, I need to confirm if these parts can fit on my m4a1. (If not, can I get the link to the right parts?)

1. Stock - http://store.magpul....duct/MAG400/180

2  Grip - http://store.magpul....oduct/MAG416/61

3. Handguard - http://store.magpul....oduct/MAG440/62

Also, is it possible to fit a Ni-mh batteries in the magpul handguard? This thread helped me a lot - http://www.kwausa.co...?showtopic=3124 - But hopefully those same batteries fit in the magpul handguard?

Thanks in advance!

The pistol grip you linked will not work. You need to find one designed for an airsoft AEG.  http://www.airsoftme...fles-BLACK.aspx

I left the pistol grip alone as it houses the motor which requires precise placement to mesh with the gearbox.  The Magpul grip shows on the RM4 (see top gun in photo) and offers no advantage, not even stylistically.  :)

Stock and handguards mounted in my KWA-CQB without modification (see bottom gun in photo).  The stock is a standard milspec M4 stock.  The handguard is the airsoft version withOUT heat shields which will have to be removed if you intend to put a battery in there.

I ran the CQB gun with an 8.4v NIMH battery orginally but soon switched to an 11.1 LiPO with a Burst Wizard 3-round burst MOSFET (not hardwired).  There's a new Burst Wizard 3 with more capability.

Magpul pistol grips tend to move the motor off center, thus putting extra stress on motor and gears.
Leave the pistol grip alone.

Magpul grip for airsoft. Has vents & is larger keeps the motor cool. There a two models, this is the same angle.
No gear stress, using them for years. The other end cap has been discounted .

IMO, an improvement over KWAs

It seems like a no for the pistol grip.. though I do wanna go two tone at some point. how do I find the links to the airsoft version of the magpul items? Also, is the carbine length suitable for m4a1?

I seen no proof that the angle is off. I had both MP motor plates & returned the discounted plate.
You will see wear on the bevel or pinion, i never do.

Some on the board swear by the other plate. IME, with mounting motors without motor mounts to slot cars. I know when the angle is off

Never seen it with the MP pistol grip. Heat will cause more damage to a motor, and the MP is larger & vented leading to a longer motor life this is the 1st part i change on new guns, JMO.

The airsoft handguards only lack the heatshields and I have to look closely at the markings to tell them from the regular models.  Carbine length fit the M4 and the KM4.

Two-tone serves to break up the weapon's outline.  Brownells AlumaHyde II "Coyote" is a perfect match for Magpul FDE -- but I'm as tired with FDE as I am with black.  My latest AR15 has OD furnature.  Nice and subtle and blends everywhere.
