    5.45 receiver dims vs 5.56 receiver dims?

    What is required to convert/modify an NDS2 receiver to make it usable for 5.56 AKmags?

    Are there 'prints' available here?

    Thanks,

    Forest

    most of the time it's just the ejector that needs monkeyed with.

    A 5.45 receiver and a .223 / 5.56 type receiver is identical except for the ejector. The 5.45 has a slightly longer ejector. Mag well dimensions should be the same.

    I have also heard that the 556 mag sits further back in the receiver and the center support rivet may need to be modified some to clear the mag. The NDS receivers have this already done. their website has a picture of one showing the modification to the center rivet support.
