I replaced my stock with a UBR with all the factory supplied screws and now the bolt won't lock to the rear. Something is preventing it to come all the way back.
What gives? |
Ok....I figured it out. I put everything together and tried to pull the bolt back and it would stop about a half inch before meeting the bolt catch. I took everything back apart and Magpul decided to include 2 of the screws that attach the tube to the stock. The other screw was in a bag in the tube and was blocking the buffer from coming all the way back. So I got an extra screw out of the deal!

| I had the same experience when I installed my UBR. Couldn't figure it out, then the third time I pulled out the buffer spring the bag of screws was stuck in the end. Magpul should add a note in the manual to get the extra screws out first. Or just stop sticking them in the tube. |
