I have a few questions regarding KA Sig 556 DMR. Here it goes:
1. How is the build quality of this gun?
2. Does it use standard version 3 gearbox?
3. If it use a standard version 3 gearbox, is the air volume enough for 550mm barrel when using 0.36g bb at 400fps with 0.20g?
4. Is the hop up unit standard M4 hop up unit, since I want to use HS5's LTH.
5. Is the any weak point in the gun that I need to be careful of?

Seeing as this gun is essentially the same as a normal King Arms 556, then yes it does have a standard v3 with a long air nozzle, and uses a m4 hopup unit. As for the cylinder, you may need a bore-up since a cylinder with no holes goes up to around 509 mm barrel.
As for build quality, King Arms tends to have relatively good products so I would assume it would be pretty good.
I used this video as a reference :

Hope this helped!

For 3: I know a fine DMR with its standard piston on a V3 gearbox, and it shoots through a 650mm barrel on a full draw. I suspect then 550mm might also be fine.

I had no idea these used a V3 gearbox. I'm going to have to get one now.

Thanks for posting this by the way. I'm going to get get the shorty version. Finally solved my v3 gearbox with mag compatibility problem. I don't care for the v2 at all, but now I can run a v3 with m4 mags. Even though it won't be a DMR, its still a damn sturdy box.
