Sorry. I don't stop in this sub-forum very often.
When I bought my Colt HBAR (Colt Sporter Match HBAR to be exact), in July, 1994, the dealer submitted the 'paperwork' on this rifle, even though according to the law(s), he didn't have to.
Now, IF I ever decide to sell it, this rifle has to be transferred just like it was a 'restricted' arm, in Maryland.
Once in the system . . . always in the system.
