Hi ! I just bought this gun about 1 months ago but it broke after 500 shot. hahaha very funny. Look like, I never get luck with M4A1 gun, this is my second AR that broke just only 500 rounds. Anyway, Here we go the story :

This morning, I just want to test the gun to make sure everything perfect before go the game , but after 30 rounds, the gun suddenly stop working but the motor still running because I can hear the sound of it. The gearbox doesn't work at all, just only motor. So I decide to take out the motor to find out what happen again. I took it out, I saw one piece of gear tongue inside the mechbox. So I took it out and take picture asking you guy what is that piece come from ?

I want to open the mechbox but the I can't take it out from the lower receiver, there is one pin above the trigger but I can't take it out. Any suggestion will be appreciate ? Thanks.

Now, I'm so tired of fixing the gun anymore and I have to leave the country next two or three day. So I'm looking a gunsmith in Montreal that I can leave the gun too. Thanks.
