Blocky Iron Sights -- Barnacle -- Foam Dart Blaster -- Picatinny Rail

Blocky Iron Sights (combined in one piece) -- Barnacle  

for foam dart blasters with picatinny rail.

I made these low profile, blocky style and clearly visible iron sights for my Barnacle.
 
It's a bit of a loose fit at my Barnacle (but it's a good fit on many other picatinny rails and I wanted it universally applicable). 
I put a small piece of 2mm crafting foam between the picatinny and the sights to avoid wiggling. That works great for me.
