Any airsoft experts?

I just bought 6 airsoft guns at a yardsale.

4 say knight's armament and are metal. Feel super high quality

1 is a giant machine gun with a drum but I can't find the maker.

One looks like a rwming700 but also can't find maker.

I also got a cool airsoft claymore, silencer, and drums.

I can text pictures to anyone who thinks they can assist with identifying and pricing. I want to sell them all but need more info first.

No clue about that stuff but.... check out the Tag-19 grenades!!!!

Maybe under a grip in the battery compartment or under the magazine there
Might be info?
