the pin should spin easy

Do you mean slide up and down?

Do you mean slide up and down?

360 spin and yes up and down

[JustinD]

Dam then it looks like I have a problem.

[GUB]

maybe try a small nail or punch into the pin hole and try and work it loose
oil or lube it also

Keep an eye on the inside track of the receiver where the charging handle rides if you have it set up left side.
The charging handle on mine was coming out of the bolt carrier every time I fired and clearly contacting this area all along the inside of the track with considerable force.
It was mangling the soft aluminum on the inside of the track badly. I guess it might not matter or affect function but I was surprised at how bad and quickly it was eating away at it.

Yep. Same with me.
Mangled to ####.

mine is gouged pretty good too, was wondering if it was just me.

Not a mark on my inner receiver (with left side charge handle)

Wide ranging variances and tolerances from rifle to rifle are no longer surprising me with this product anymore unfortunately.

No but an Mlok QD attachment can be had for $20.

Can now confirm mine does. The foremost hole in both left and right side of the handguard are both qd compatible and the end plate is ambi qd as well. With fake magpul from amazon it works anyway. No adapters needed for qd slings.

Hi Travis, If the bolt goes rearward to the point where the charging handle engages the rear of the slot, and then falls out, I would definitely be concerned with such excessive over travel. I do not have a WK as of today but if this issue is common and not a one off, it is of concern for myself as a future recipient. If you could post photos it would be a great help. I also understood from the YouTube videos that the charging handle was only removable in disassembly. PLEASE KEEP US POSTED.
