You do know that M16’s are not “machine guns”, right?
Only if they are full auto!
Most M16 stamped receivers definately are machine guns, specifically/technically, "SELECT FIRE", true assult rifles.
I have three (3) of them on ATF form 3s.
Price: H&R M16: $25,000.00
Colt M16A1: $22,000.00
M4gerty (Olympic Arms lower): $15,000.00.

There are even full-auto AR-15s from the factory for LEO.
MOST (99%+) AR-15s are full auto unless converted prior to May 19, 1986, or mfg after that from an 07/10 FFL with a Class 2 SOT.
