I have a colt A2 style rifle length upper.
The front sight does not have a bayonet lug, I want to swap it out for one that does. what should I look for? (I know about the barrel thickness .75") I know that not all FSB have pins at the same spacing - Is there a couple "standard Sizes" used here or will I find that they're all a little different? I have all the hand tools that would ever be required for removal/replacement.. |

I've got a carbine that has a bayo lug but my rifle doesnt.
one is 1-1/4" spacing one is 1-3/8" spacing I am just curious as to how many different spacing sizes there are for a 0.75" thick barrel. I'm familiar with the process, im unfamiliar with "front sight base variations" over the years. (the rifles in question are late 80's, early 90's) |
