||I've had three of these guns and i love them. HFC makes good quality affordable guns! All but one of my guns is stock. The upgraded one has a threaded barrel and silencer. Now for the pros and cons.
Heavy weight, feels just like the real thing
Awesome blowback effect
Runs fine on propane
Good mag capacity
Tac rail to mount laser or light
Trigger spring. The trigger spring on 2 of the 3 guns i have had have broken. Now, this may have been due to stupid friends pulling the trigger constantly when they weren't shooting, but i don't know. My advice is if you buy this gun, only pull the trigger when you're actaully shooting, not just to click it.
I give it a 4/5. Only a 4 just because of the trigger spring.
