Picatinny Rail
 

I was looking at this add on rail from Seals Action Gear Picatinny Rail Short and I was wondering if it anyone would be able to tell me if it would fit on the handguards of a CA M15 A4. Thanks in advance!

if your vent holes are .75 inches to center then yes.

I bought one there for my foregrips and it fits fine. I did shim it up a bit with a washer to make it a bit tighter as I was running an M900 light.

Yeah, I checked my forgrip, and it was 3/4" but I wanted to double check anyway. Thanks guys!
