Please help ID these vintage parts!
 

Hi guys,
Got these mixed in with some GI Joe stuff, no idea what these are. Any help is greatly appreciated!

1. Some kind of brown grate or cover with four clips. It's about 3" long and 2" high. I have no idea what this attaches to.

2. 2.5" long brown projectile with a sticker on it. Power Rangers maybe?

3. 2" long purple claw/grabber of some sort. Looks like it has two handles and maybe something attaches to the hole. Ghostbusters maybe?

4. Large rubbery 3.5" by 3.5" machine with a backpack attached. There is a peg inside that looks like it attaches to a figure. Also has a horn or shell sticker on it.

5. Large 2" by 2" Black projectile or removable head. Has one green eye and the piece is very light. Looks like a Batman piece but I have no idea.

6. Small 1" by 1" Black twin gun with a bullet belt. Black and very flexible. Has a slot on the back, have no idea what it attaches to.

#4 - Barnyard Commando!

5 Looks like Lego Bionicle related. It might have a part number on it.

Thanks again guys! Can anybody help with the rest?

So that machine gun on the bottom looks like it's from Commando's Chopper
Item: Chopper

But I used to have that figure I thought his machine gun chest attachment was one piece. Maybe I just don't remember well.

There were 6 inch versions with similar accessories, but I don't see Chopper in that scale.

Thanks Sean! I researched it and that is Choppers gun from the Diamond Toymakers Commando line. It's two pieces, mine is missing the attachment that fits in his body. Thanks again! Still trying to figure out what that weird purple piece is!
