I have an A1 Stock that I got on a police turn-in Bushmaster. The stock screw is stuck on the receiver extension. When I try to unscrew the stock screw the receiver extension turns. I have tried spraying WD-40 on it from both sides and letting it sit for a day or so. I am not having any luck in getting it to let go.
Suggestions? |
| When working on stuck screws, bolts, etc., forget the WD40. Get some Kroil. That stuff is magic on stuck bolts. |

One whack with a hammer and it will break loose. http://www.harborfreight.com/impact-screwdriver-set-with-case-37530.html |

Surely someone was not ignorant enough to use red Loctite.
The threadlocker that is applied to these screws normally does not require heat to loosen. Either way you are going to have to pull the tube and secure it. I have found that the proper size hollow ground screwdriver bit makes working with these screws easier. |

"Unscrew the extension out" How do do this with the butt stock screw locked up? . With it locked up, the screw at the butt plate will spin the buffer inside the stock body. this is where I am at. I got the extension loosened up before I realized it was the extension I was loosening and not the bolt. So, the issue is, the extension turns instead of the stock screw. Granted, it does not turn freely, it is pretty tight. I think I will pick up some Kroil tomorrow at Lowe's/HD and see what damage that can do. I have a sodering iron I will try next. Beyond that, how do you secure the extension so that it is only the screw that moves, and not the extension? Thanks |

RED locktite is what is used on these screws..... |

I was an armorer in the 70’s when M16A1s were in general issue.
The factory threadlocker on those screws does not require heat for removal. If anything the problem was keeping the damn things tight. If someone did use the high strength red on the screw you will need to get that screw smoking hot to break it loose, but it is much more likely that you just need to clamp the tube in a vise and use the right screwdriver to get it apart. |

Drill the screw so the head pops off, pull the stock off and grab whats left of the screw with a pair of vice grips. Thats what we do at the shop.. I had the same problem as the OP and this is how i got it off. I tried four or five different things, which all turned out to be a waste of time. This method is the surest way to get it off. |
