Ok so I'm pretty much sol with that barrel and reverting back if i wanted, just on the fence if I wanna give up the m4 look, gonna be putting an omega x rail on it and it's a carbine gs, to bad I didn't get an omega fsp, also have a lite rail I plan to put on a bcm bfh in the future so wasn't sure how I'd like them being so similar when all set and done, would you guys even bother free floating a 16' spikes carbine length m4 style upper?
