| Learned something new. The F mark is on the left side of the FSB to denote the higher FSB not on the right. |
| To make it even more confusing... Armalite doesn't mark their FSB with an F... So, all the web chatter and their own website says. However, this year, they started installing F marked FSB's on their M15. I called them about it and after some confusion on their end, someone comes on and says, their vendor marks them but they are not full height. Anyway, I guess I should get out the ruler to compare but it didn't really matter to me. The rear sight worked fine anyway. |
