| If you look at my rifle HERE you will see that it has a 5 1/2 in. flash hider on it, with a 11 1/2 in barrel. but what the problem is, is that when I sanded down the edges to see where the pin is to take it off for a barrel change, there is no lines nor any evidence of any pins. I am asking because has anyone ever heard anyone putting these on with loctite or something. The ar15 in the picture has the shorty barrel with the long flasher on it and wanting to change it over to a straight 16 incher, and for my new project my tactical entry is going to use the shorty barrel. the shorty barrel is a HBAR from LMT, I am asking if I twist it off hard do you think it will come off? and also I sanded it off just using my hands, no dremel or tools. I bought the barrel assembly from a dealer of LMT. so do you think he couldve put it on with loctite? also what could be the consiquence of trying to twist it off with it "having" a actual pin in it? |

I understand that any of these manufactured in the 20 or so years will have a blind pin to make it a permanent installation. Also I have seen lots of them built in the 60's and 70's that weren't pinned. I presume yours is the former. Loctite wouldn't be a legally permanent installation. If this is a volume AR parts dealer they may be able to tell you if it's a brand they sell. If it's a trade-in to the dealer, or a brand X barrel, you may be on your own as to how it's assembled. I wouldn't recommend trying to take it off until you disable the mounting arrangement--the blind pin or whatever. If you do, you will likely wind up ruining the barrel, or some tools, or something you don't want to mess up. Others may have more helpful suggestions on what to do to determine this but all I know to do is to take off enough finish to find the pin--and hope it really has one. |
| Here is a trick that sometimes works. When you sand off the finish, if the pin was dressed down really nice even with sanding the pin may be all but invisible. The trick is to take some liquid cold bluing and "touch up" the area you sanded. The pin and the FS will likely be different steels and will take the bluing differently. IF this is the case, the pin will stand out like a sore thumb if it either takes more bluing or none at all compared to the FS. Like I said, this does not always work but I have seen it work on more than one occasion when trying to locate the welded spot and is a very quick and easy test to try. |
