WE HK416 GBBR downgrade

[BrokenBird]

I am new to the GBBR word and just got myself a HK416 and I am not sure what to do to lower the FPS. I read a bit about npas but I am not sure what to get. I do think my gun is closed bolt.

thanks.

You need an "NPAS" valve installed
Contact your local gundoc

You need a NPAS. RA-Tech makes them.
I suggest you read this over in order to understand the gas system and some of the problems you might face.

your gun should be closed bolt as i don't think they've released the open M4 type bolts yet. Closed has the large brass tube in the chamber.

Is there a close bolt to open bolt conversion kit for the WE HK416?

Not yet

Supposedly going to be released end of this year which is apparently very soon.

Hi Broken Bird, in order to lower your fps Ra-Tech makes a Npas kit. There are two versions available, one is just the valve and the other is the valve, plus a hop up and a few steel parts. I recommend that one. Send me a pm and I will show you links. You do not need a gun doc to install a npas on a WE, it takes 30 seconds and is idiot proof.
