Hey guys,
Heres the question: Can I swap the front sight base from my bushmaster M4 to my dads colt Hbar 16inch? are the gas ports, pin slots and all that jaz the same? I will measure the actual diameter of the barrel under the FSB when I get home but I wanted to make sure it wouldn't be a problem. Here is why: I want to put a 10 inch rain on my upper, and my dads colt FSB is a preban w/o a bayoney lug. SO I was going to cut down his FSB to fit under my 10 inch rail, and he would get a FSB w/ a bayoney lug on it! Win Win!! What do you think? And thanks for you help in advance! Eric |

I can say with 99% certainty that no, it can not be done.
FSB’s are match drilled to the barrel. No two barrels are drilled the same. ETA: Recently covered.........http://www.ar15.com/forums/topic.html?b=3&f=4&t=418494 |
