grasshopper_no_more Posted January 11, 2011 Share Posted January 11, 2011 I was wondering if the JP front sight with the adjustable gas system is the same height as an F marked fsb. I plan to use this with a flat top AR and a detachable carry handle, so Im worried about zeroing issues. This sight looks very useful. I can adjust the gas pulse to the type of ammo Im using, and I can save a lot of time not having to send the barrel in to have a FSB pinned. thanks in advance.

carbon9 Posted January 11, 2011 Share Posted January 11, 2011 I do not know if it is an F height. If not, this may help and it may not. Good luck. Link to comment Share on other sites More sharing options...
spd522 Posted January 12, 2011 Share Posted January 12, 2011 I have a MI folder on my JP gas block and a non-folding DPMS A2 rear. It is the taller made-for-gas-block version and it works fine. Craig Link to comment Share on other sites More sharing options...
