| I have an Sp1 reg receiver MG and want to put a new barrel on it. Will a F marked front sight work with the A1 carry handle rear? |
| It can; the difference is that the deck for the front sight post is .040" higher than that of an unmarked FSB. You will quite possibly be able to crank the front sight post down far enough to zero. Worst case would be that you'll need to grind a little off the top of a standard FSP. |
