Question about SBR form 1
Posted: 26 Feb 2016, 08:48
I bought a barrel and flash hider from cmmg and shipper it to my FFL and I'm not sure what to write for barrel length. I know the barrel is 10.4 but it has to be threaded into the flash hider to keep the reciver together as a unit. Should I put down the 10.4 for the barrel on the form or should I measure it with the flash hider on? I've never done a form 1 and I know alot of you have used the cmmg setup.
