If I have a mid length gas system and an A2 FSB what length free float can I get that will fit with my front sight? What length is the space from the upper reciever to the back of the front sight block? I am looking at some cutouts but would rather not get a cutout.

You want THIS ONE If you don't feel like driving out the FSB pins.
If you remove the FSB, you can use any 9" FF. I have an APEX modular on one of my midlengths. For a good quad, it is hard to beat that Centurion. |
