Unknown double barrel gun
 

Found this among some old 80's/90's toy parts in my parents' home, but can't recall what it went to or find it online.

Any ideas? The hold in the middle seems to be designed to snap onto a connector.

Thanks

Anyone have any ideas on this one?

I forgot to mention it's pretty big: about 3 inches x 1.5 inches

IDEAL's ROBO FORCE Fortress Of Steele from what I can tell.

Thanks! I searched for some photos, and though it's not pictured with accessories, it does look like it's the gun from the top of the fortress. Not only that, but the sled controls part is another item I remember seeing around somewhere. Strangely I have no recollection of my brother or I having this set, but if two parts of it are still around, I guess we must have...
