Thanks for the reply folks. Sometimes it feels like we live in a police state... I won't give any reason for the authorities to reclassify these units.
..... as long as you only use it at the range when the 11 inch is installed......
Even with that I think you are still treading in a very gray area, The law says you must inform the CFO within 30 days if you intent to keep any modification to the firearm that will affect the classification, I will not be surprise when a judge interprets simply being possession of the shorter barrel is your intention to "keeping the modification", especially given a rifle like an XCR where the barrel can be changed without any special tools within a minute.
