I received a complete M4 upper from Bushmaster direct through a trade deal with another member. The upper is a dream, and shoots very well.
Anyways, onto my topic. I requested an actual 14.5" with a permanent Phantom to make it to 16". How can I find out if my flash hider is in fact permanently installed? I really don't want to lock up the barrel and try twisting on the phantom. I've been told that Bushmaster uses a blind-pin method of permanently attaching these things, although I'm not familiar with the process and what the end result would look like.
Help me out, and keep the BATFE off my a$$. I like my 14.5", but I want it the legal way. (Yes, Texas is SBR friendly, but going home to Michigan within the year, and they are not SBR friendly.)
