I watched a few videos on youtube and I am going to disassemble this afternoon and try to figure out the issue. Have a lot of experience with AR,s and AK's , but this is a new platform for me so I'm going to take it slow and get this issue identified.
Also the button to fold the stock is difficult to press. Funny I can lightly push it down on the surface of the work bench and it breaks free but I can't push it with finger pressure.
On the plus side, everything that came with the rifle is brand new except the magazine pouch.
Here is how I take mine apart.
1. Push out the Pin that goes through the Sear. It's the top
one when you look at the left side of the rifle.
2. Push down on the spring that is pushing on the Safety. It'll have a small
divot almost at the end. You can use that pick that comes with the cleaning kit
to depress the leaf spring to get the Safety out.
3. Tap out the small roll pin from the bottom out the top of the receiver
to get the trigger out.
Use a lot of oil.
What I did was use Ballistol in the Spray can and sprayed a
a lot in the receiver, bolt carrier, bolt, springs...etc ect.
Put it back together in the reverse order.
Then keep racking the Bolt carrier over and over.
It's going to peen 4 spots in the receiver. This is normal.
Then pull the trigger. it should work now.
With the folding stock I had the same issue.
I just put a bunch of oil in there and worked the button
with the handle end of a hammer. Just pushing it down about a couple
hundred times and it works perfectly.
