HK_Shooter, you'd better specify...otherwise, they might mistaken me for you
Oh, yeah, Accountant30339, if you want to do as P806 suggested (16" with a sleeve) IM me. I have a sleeve that looks like the 5.5" FH but actually fits on a 16" barrel just like a regular FH that you can have.
ETA: Added pic. Also, I just looked at it...it won't be quite the same as a 5.5" since this one has actual FH slots and thus the threads are about 1.5" from the slotted end. It'll make it look like you have a ~13" barrel with a 5.5" FH.
