| which one do you use on front sight. several types of lock-tite on market |
|
No loctite on the front sight post. The front sight post is held in place by a spring and detent pin that will press up on the post slots, they go in the hole in front of the sight post. If you asking on the setscrews used on an adjustable indexing tower, for the setscrews that are on the bottom against the barrel, then Blue works the best. It allows backing out the setscrews if needed at a later date, without needing the heat the assembly up to break the bond. |

Most 'smiths building match grade guns use locktite on lots of parts. If you are lineing up your front sight, I would do it this way. Knock out the pins and clean the sight housing and barrel; Drill and tap the bottom hole in the housing for a hollow set screw to hold your settings while you get it right; Reinstall the sight housing with the set screw; Take lots of ammo and the right allen wrench to the range, center the rear sight, and shoot and adjust the front housing until it hits center; Weep in green Loctite - the kind that penetrates assembled parts. Yep, glue the whole thing to the barrel. It won't come apart until you want it to. A heat gun will be needed to disassemble it, but that won't be for 4000-7000 rounds (match limits, longer for rack grade requirements). This is how it is done on NRA High Power rifles. If you just try to Loctite the screws, it WILL come loose. We have seen this around the club. Just glue it all together with green Loctite. |

Quoted: going to use it on front tower,it is leaning to the right and i cant line it up. will have to remove pins. was told by some just to lock-tite it in place. BLUE or RED? I'm not sure if it's either one. There are many more types than that. I'd ask Bushmaster tech support what they use. All I know is that it takes a heat gun to break it loose. |

Loc-Tite is a bandaid for other problems. There is never a need to use the stuff on any gun assembled with compliant "mil-spec" parts. All the stuff does is make the gun difficult or impossible to service later without ruining parts. The only part is a stock rifle with anything that resembles thread locking compound is the fixed stock retaining screw. I have never seen that screw come loose even without traces of that "blue stuff" on the threads. If threaded fasteners are installed (torqued)correctly to the specified values, there is no need for Loc-Tite. |
