Firstly, this is some high quality parts package. I have no way to verify it's dimensional accuracy but my gut tells me it is NASA quality.
I installed this FCG in a Receiver made by Ohio
![Huh? ???](https://czfirearms.us/Smileys/default/huh.gif)
I have had other problems with this receiver is a fact that should be noted. My problem was that I couldn't get the sear to release the Striker. The engagement was just way to much. The CNC sear doesn't seem to move down as much or as far as the OEM parts. That should account for the CNC having less creep or let-off or travel. The CNC is smooth but that counts for little if it won't go bang.
My fix was to file away the latching surface on the Striker till it fired. I removed a lot of material and I tested and blued all along the way partly driven by fear. It now works very well....I think. I have had many FTF and JAMS but I think that is due to the Receiver feed ramp irregularities.
I experienced the "gremlin" a few time out of 90 rounds. I cut and welded the piece that modifies the Carrier for that problem. It seems like such a straight forward fix I don't see how i could have gotten that wrong. Any ideas?
I have looked at maybe 5 different Strikers. They all "look" to be the same dimensions. NONE OF THEM has a engagement signature from the Sear that is close to the same. One is about 1/16 inch and that is by far the smallest and the rest go up to 3/16 inch. All of these were paired with OEM FCGs.
Thanks,
John
