Ok, my Noveske complete rifle arrives soon, along with the free lower. The rifle is a low profile recce. For the build, I am considering a 14.5" carbine to have a little variety to the recce. So, if I get a 14.5" with a permanent flash hider to make it legal length, can that flash hider later be removed if I convert to SBR? Also, I may just get a "basic" for the upper...is it reasonably simple to later change the hand guards to rails? Lastly, I want to put a magpul UBR on the recce, and use the stock I take off for the build, this is easy enough as well, right?
