upgrade for KWA MP7

heman90210 · June 21st, 2015, 21:28

Hi, I have the KWA MP7 Sub machine airsoft gun. The gun is a H&K airsoft blow back gas replica. I think It's brilliant, but, the full automatic feature is lacking. I have never been able to finish a full clip on automatic fire without the gun malfunctioning. After two shots It will release all the green gas out from the magazine.

I took it to airsoft tech at trigger airsoft in Richmond. He said that was normal because when gas expands, it cools further and that make the mag too cold to function.

I know that KWA makes good guns as I also have a KWA Kriss vector as my primary. So I wanna know is there any internal upgrade ,or attachments, I could utilize to allow full functionality at full Automatic fire?

what do you need automatic fire for?

That's definitely not normal. Not sure why you need a mag dump anyway but burst firing my MP7 and I can get more than two mags through one gas charge.

Put in a tightbore barrel an a new hopup rubber an you're good to go.

The KWA MP7 is a KISS piece of kit.

Thx for your input guys. To answer some of your questions; I don't need full auto fire, but I want full auto fire. You could use full auto fire to suppress fire on target and allow a teammate or fellow soldier to advance position. It also works great when combined with a grenade. Although I used to be a soldier for the Canadian forces so I can get by fine on semi auto. Anyway, if I wanted a semi fire only weapon, I would have bought a pistol like a Glock or 6p9.

So I am to understand that my inner barrel and hop up are inefficient? Do you recommend anything? Brands?

Try the A+ REAPS, although the last batch seemed to have some issues with them. Required a bit of teching to get it running properly. My stock barrel is accurate to about 135 feet using .32s with Green Gas. I can reach much further than that but I can only reliably hit a 9" pie plate at about 135. Although that is from standing position.

I like the Falcon bucking.

Falcon and PDI both make good barrels.

Great, I ordered a precision falcon inner barrel. Still undecided on which rubber bucking hop up to get. Thx for the info guys
