Are these FNC parts? (Photos)

These were in my box of FNC parts. The spring is about 1 inch long. If I recall correctly, they were advertised as parts for the gas system when I bought them years ago, but a buddy believes they are fire control group related. All three came in a bag together labeled "543". The piece with a point and spring do look like they could work with a selector, similar to how an AR selector lever works. I'm not sure where the roll pin fits in.

Thanks!

543 is the hammer spring rest so that is not it. I does look like 161 indicating plunger, 162 retaining plunger spring, 163 retaining pin- indicating plunger, found as part of gas cylinder assembly.

Yep, part of the gas tube.

Excellent, thank you both for the info!

Correct ID on the part.
In our army, it is not a part we replace often. They just swap out the complete gastube assy.

And to the USA FNC owners, If you need parts, contact member FUATOS, no need to PM me unless he hasn't that particular part.
