Check-Mate M14 mag pins

[BeaverMeat]

Interested in picking up some Check-Mate M14 mags. Before I hit the checkout button, I want to know what is the pin style. Internal pin, rivet on the mag spine, or spring retaining dimples?

Thanks

I have one that's on the side...

Mine were on the spine.

Sounds like you need to call the retailer.

Got it second hand. No other holes.
