Picatinny to Arca adapter loose fitting

Last edited:
I bought a small picatinny to arca swiss rail adapter. It doesn’t fit my M4 or Krait on any of its picatinny rail but fits my Maverick’s picatinny rail.

Noob question, but is picatinny not a standard size “mil spec” in example? See videos below.

Not sure if I can explain this but will try. If the threaded bolt holes on the top pinch rail go all the way through turn the pinch rail around so the thickest part is behind the Pic. rail.
 
That's odd but you might want to purchase a different manufacturers Arca Swiss to Picatinny adapter to see if it will fit your M4 as the screw attach types are relatively inexpensive, I have one for my Taipan V2. There is also a Vanguard Quick Release version on amazon. You can always return it.....

Weaver and not Picatinny on the gun?
It's not weaver. FX states it's a picatinny rail on the sides.

Hmm. Might have to look into that.
