If I have an upper for an AR10 that has what the BATF calls a short barrel installed, how do I go about SBR'ing something that doesn't have a serial number? The lower has the s/n on it, not the upper.
Sorry if I wasn't overly clear. You can remove the shorty and use the longer barrel, but if you install the shorty, it needs to go back on the registered lower to be correct and lawful.Yeah screw that. I have 3 other uppers, different calibers, with "normal" length barrels. I'm not going to dedicate a lower to a short barrel that'll probably shoot like crap anyway.
Thanks for the answer though![]()
Oh... derp... that makes sense. I can live with that.Sorry if I wasn't overly clear. You can remove the shorty and use the longer barrel, but if you install the shorty, it needs to go back on the registered lower to be correct and lawful.
