Just a note for other that may read this.
Your application WILL be red flagged if you list a rifle as an AR-15, AK-47, etc.
Why? Because the Roberti-Roos Assault Weapons ban banned certain firearms by NAME such as Colt AR-15, Poly Tech AK-47, Maadi AK-47, etc.
While a Bushmaster XM-15E2S is an AR-15 family weapon it is NOT by NAME an AR-15. All previous "AR-15's" were supposed to be registered during the last ban (Roberti-Roos).
Calling it an AR-15 would cause a red flag where as the manufacturers name, such as Colt Sporter, does not as it is not BY NAME an AR-15.
The same applies for an Olympic Arms PCR rifle, etc.
