Aero M5 Reciever/Bolt Catch Issue

[hurricanecasey]

Yea filing down the bolt catch was the original plan but since my buddy had some extra .308 parts i tried on of his bolt catches and it worked so i traded him. like yall said it may fit on a different receiver or whatever. just glad i didn't have to send my receivers back to Aero. On my thread on ARFCOM Aero acknowledged that they don't make the catch in house its sourced and that also the hole in the catch was probably out of spec. Sad that they can't catch that crap when they get it from their source and ship it out to people.
