FN 5.7 : Adding an RMR

[CDR_Glock]

Having an extra RMR I wanted to see how this performed. I have used red dot sights on my 5.7.

Well, the newer design just requires removal of the rear sight.

Tools I needed:

Precision mallet
1/16 punch to remove the pin
Flat head screwdriver
Blue Locktite
Bench vise to compress the roll pin.
3/32 roll pin punch
Lots of oil

The easiest part is removing the rear sight. Use a 1/16 punch to remove the pin. Screwdriver to remove the rear sight.
Screwdriver to attach the mount. Then, I tried to punch the roll pin without compressing. That didn't work. I used the bench vise to compress the roll pin. Then I used a 3/32 punch and gently tapped it through.

Blue Locktite to secure the RMR to the mount.

I set up the RMR for 25 yards. Was able to shoot it out to 50 yards very easily. It's a flat shooter even at 75 yards.

I was able to hit 150 yard plates, also, with a slight holdover.

With the RMR the target acquisition it fast, and it is consistent. No issues with reliability with the gun at all. Not with an RMR. I used SS197.

I'll tell you that ASTIGMATISM is the major limiting condition that may hinder your ability using a red dot/reflex sight.

Looks like a sweet set up! Enjoy! I have been eyeing the FN 5.7 for a while... My buying finger is itchy.

Thanks for sharing your project and pics. An FN 5.7 is on my short list of new handguns that I eventually must own. My old eyes would benefit from what you did to yours. Nice job.
