Ok so I think I'm going to do something with this dissy barrel I've had laying around (BCM chrome 1/9 M4 cut) but I'm really wanting to run a 16" barrel and floated....however I'd need a 2 pc FF tube or remove the fake GB to install the tube then put it back it on...

Or just send it to the EE and buy a carbine/middy 16" barrel and 1 pc FF tube...

Any other options?
