Colt AR-15 A2 Gov't Carbine
used police gun
This belonged to a Douglas County Sheriff's Office deputy who was selling some of his guns to go to law school.
I purchased this from him in March 2020.
no box or other accessories
marked RESTRICTED MILITARY / GOVERNMENT / LAW ENFORCEMENT / EXPORT USE ONLY
This was required during the assault weapons ban (AWB) of 1994 - 2004.
These have been legal for civilians to own since the ban expired in 2004.
After the ban expired in 2004, Colt continued to apply the RESTRICTED roll mark on their AR-15s until about 2012.
Israeli soldiers - some off-duty - with M-16 carbines with fixed carry handles and lightweight barrels, similar to the Colt 6520.
Note that the IDF carbines have A1 style sights.
