| I have a commercial CTR that is loose on the tube. Compared to my millspec its driving me nuts. I would imagine its from the tolerance difference between the commercial DPMS tube and my BCM mil-spec but has anyone seen a link to a mod to tighten it up a bit. I thought I saw a thread somewhere but I cant find it. |
it's loose after you hit the locking clamp? Have you tried testing it on another tube? Are you certain you've got a commercial stock on that commercial tube? 
I'd test it with another tube, and if it's still loose, contact Magpul, before making any modifications to the stock. |
| I just went through this with the two that I have. Drive out the roll pin that secures the lock. Remove the lock and on the inside of the lock you'll see a metal piece. Carefully pry the unsecured end out slightly so you can grab the edges and squeeze them together a little. Like I said, carefully. There was a posting awhile back that someone did this and the metal piece broke, but was able to get a new one from Magpul. Don't know if he got a new lock or the metal piece. |
