FSB Install Option

[HKGuns]

Did you dimple, for the screws to "settle into", the way we do for lo pro gas blocks?

Because my issue with this would be rotational torque on the FSB from an impact against something, as a slight misalignment would mess with your zero.

I did not dimple as I didn't know if the FSB would align with the dimpling jig I use (KAK) for low profile gas blocks. I thought about it, hard, but decided since the set screws I use have knurling on the ends it would probably be ok. I actually had the FSB in one hand and the jig in the other and my brain was trying to figure out if the holes aligned.

But you are correct about the FSB rotational force. That thing is a big lever.......

Since you mention it, I may now go back and dimple as I'll have marks I can use to guide the dimpling.

Should be fun getting the rocksett out.
