Speaking of AR-15s, my dad now has two Colt A2 HBARs, and one A1 SP1 in his shop. One HBAR is pre-ban so it can keep its bayonet lug and A2-flashhider, while the other is post ban, so my dad sadly had to grind off the bayonet lug and replace the flash hider with a Miculek muzzle break. It's still a nice looking gun, but it's been '96 neutered. Clinton/Biden, you cocksuckers.
The SP1 was pretty nice, I didn't check the caliber markings though.
This is the most "assault rifles" my dad's ever had out in the shop. And now he's bought the Bushmaster and the Jager AP-80, so I'm pretty happy. I'm cradling the Jager as I speak.
Hell, I'll take a picture...
