I'm making a shooter out of an M16A2, making it ar15 post ban legal. I removed the flash hider and I'm putting the Calvary Arms Compensator on in it's place.
The compensator screws on OK, but it doesn't align correctly. I'm assuming the cuts in the comp should be up and the pin hole should be under the barrel. Mine lines up with the pin hole up and the cut's on the comp under the barrel.
Any good suggestions on how to correct would be welcome? Anyone else run into this?
Get a Peel Washer, then you can index comp.
