Can I safely use internal parts machined for a US Ordnance right side plate in a Rapid fire gun. The internal parts fit no problem in the ORF gun. My Rapid fire gun lock frame right arm is cracked and the Rapid fire sear broke today. I swapped out the lock frame,bolt with KMP trigger and sear and fired 20 rounds in this set up with no issues. Can I go ahead and run a 250 round belt through it now without worry ? Thanks.

I guess I would lay them side by side and see if the machining is the same for the denial island. I would not be afraid to rip a belt through it if they are the same...

Yes the parts are almost identical I believe the parts are machined slightly larger but they fit in the receiver well.
