New questions, everybody.
I've got my rifle almost complete. I have a 16" barrel with a midlength has system. I also installed a standard A2 FSB. But I'm considering trying a free-float handguard. Since I went with an attached FSB, I know a regular 9" (since I went midlength) handguard won't fit, but what if I bought a carbine length free-float handguard? Has anyone else done this, and how do you think it'd work?
Also, where are the points you measure from to determine the handguard length you need? Is it measured from the flat back of the FSB to the flat front edge of the upper receiver?
