Hey guys,
I'm getting ready to send off two SBR forms and have seen differing instructions on 4f- overall length. My intentions are to buid one of each, a 10.5" and 14.5" rifle. When I measure, I get 27" and 31" respectively, on a guess of course since I'm not allowed to assemble completely.. Now, my question is, what if I decide to buy a 7.5" upper?? I was under the impression that an SBR was an SBR and you must always possess the registered componentes regardless of how it happens to be configured, but you werent required to perminantly keep them together... What if my 10.5" upper ends up on my 14.5" registered lower? The OAL will then be 4" shorter than registered.. Is that really a problem??? Now I'm also begining to wonder if I'll be allowed to pin a 300blk upper on them at any point.... Just trying to cover all my bases before sending out this extortion check.. Thanks for the help!
