If it is not non restricted it kind of doesn't matter to me. I may just get a another conversion done on my ACR if there is nothing out there with a .311 in NR, or wait for a unicorn like the CZ 805 to come to civilian market. The desert tech MDR looks interesting as well but who knows if they will do the correct bore size.
If it's either loud, obnoxious, fast, hated by the general population or any combination of these, I OWN IT!!
Both the ArmaLite M15A4 caliber 7.62x39 and the XCR-L caliber 7.62x39 have .311 bores, we have both in stock.
