Just starting out and was wondering if someone could give me a tutorial on the proper procedure to adjust feed from the mag and modifying the thickness of the selector stop plate. Is everyone doing this? What if you need a thicker plate? Do most of you use a new selector stop plate under the trigger guard? Thanks for the info.

If yo fit the trigger guard first then the front trunion to a couple of mags everything should work out fine without altering the plate.

I've had to thin a couple out, but I have not run across a case where a new plate was not thick enough.
Only had one, where a new plate was required. The original was pretty worn.

Before you start mods on the selector stop, make sure that the front trunion is in the proper location.
On my tantal build (ak74 style), I had to file the receiver in front of the selector stop.

This is what you do
Get some small bolts and nuts that will fit the triggerguard.
Bolt the trigger guard in place.
The put a mag in the mag well.
Slide the front trunion in so it is TIGHT against the mag.
put a C-clamp on the reciever section above the front trunion.
Once the clamp is tight, check the mag for looseness.
If the mag is loose then file the receiver (right in front of the selector).
Once you file the receiver you will need to loosen the clamp and slide the trunion back some more.

If you are using a matching #'s kit, and you are pretty sure the trigger guard came from that kit, you should not have to file the selector stop if you follow the above steps.

Thanks all for the advice. Looks like the key here is to mock it up with screws and verify function before riveting anything!

When you do this...

Insert that mag with a couple of action proving dummys. Take the bolt & slide it forward on the rails, and see how much engagement you get between the bolt & the dummy round. You will know right away if the mag needs to ride higher. To get the mag to ride higher, thin the plate on the RECEIVER side.
