selector filing for geissele trigger

[ilikeguns111]

I don't get where exactly I'm suppose to file to get the trigger to fire.

I just bought a national match geissele trigger I cannot dry fire it with the selector installed.

The instructions point to the outer left edge of the selector but what exactly am I suppose to file the little outer circle of metal down or widen it?:confused:

Is there a selector that I can buy that will fit without any modifications that will work with this trigger?

These were specifically checked to fit GA triggers....

Thanks Trident.

I called up Bill and asked what we could do on our end to make the DMR work with folk's receivers without them having to modify their selectors. Bill was very helpful and gave us what he deemed necessary to make this happen. The issue is with the receiver and the selector, but mostly the receiver, if it's in spec then there wouldn't be issues.

In PIP2, we widened the selector flat as much as possible, to allow slightly out of spec receivers to use the Geissele DMR.

This picture demonstrates the amount of clearance with the DRM ;)
