Mega ambi lower and lpk fit?

[WxWatcher]

So I have a Mega ambi lower and was working on assembling it with a Spikes enhanced LPK. On the Mega, the bolt catch release is held with a "bolt catch retaining screw", not a roll pin. The roll pin will fit through the appropriate hole of the bolt catch release, but for the life of me, can't get the retaining screw through.

Is the retaining screw a slightly larger diameter (on purpose) than the roll pin? just drill or file the hole on the bolt catch to get it to fit? Thanks.

Small burr on the catch, a few passes with a small file and all is well. Carry on.
