I've got a barrel that had a standard FSB on it. I removed the FSB (the sucker was TIGHT) and now I am installing a low-profile Troy gas block. This guy does not want to go on.. I've been tapping on it and it seems like it's stuck. Is this normal? :0
ETA: <sigh> I just saw this thread posted a few below mine.. http://www.ar15.com/forums/topic.html?b=3&f=4&t=474919 |

Quoted:
A small amount of sanding is sometimes required. Alternative to that, you can use a little science. Place the barrel/upper in the freezer for a few hours, and warm up the Troy, she should fall right on,  Yep,, once I read the other thread, I felt better about using my Dremel attachment :0 It took about 30 seconds to shave a bit of material off and squeeze it on. Still a very tight fit, but no hammer required. |
