I'm having a hard time adjusting my FX rings for 100 yards after purchasing a new Sightron scope. It's hard to make small adjustments to get it just right. After a lot of frustrating attempts I thought of using a feeler gauge to hold the rear ring in position while tightening it. Is this a reasonable approach? This is the first time I've tried to do this.
Adjusting FX No Limit Rings
- Thread starter beeser

Keep the front one completely loose, tighten the rear so it takes some force to move it. Playing with it I was able to center mine. Got to find just the right tension on the rear that you can move the scope without moving the gun.

I was under the impression that they were primarily used for large adjustments. Get it as close as you can and then use the turrets for final fine tuning.

beeser,
I mounted my scope using no-limit rings. The scope was optically centered. The rings were in the lowest position, and the scope reticle was correctly leveled. I then used a feeler gauge... snugging and loosening the rings, l was able to zero the scope at my desired distance without elevation or windage turret adjustments. I raised the rear .031". I got lucky.
An adjustable cheek rest helped...no need to adjust both no-limit rings to get the scope to the correct height. I enjoy the process....I use feeler gauges often.

Hey beeser....... Could you post a picture with the scope mounted? I would like to see the Sightron with the FX rings.

Motive410 - Thanks for confirming that my use of the feeler gauge wasn't without merit. I was sighting in at 100 yds and was close to my POA raising the rear .020". I plan to do some work on it tomorrow. Since the scope was brand new I assumed it was optically centered. Is there a way of telling for sure?
Dirte - I'll post a pic of the setup tomorrow.

beeser,
The easiest way to get close to center, since the scope is already mounted, would be the mirror method. (Small mirror) You can google " how to center a rifle scope". The mirror method, turning scope in v-blocks or loose rings, or counting turret turns are the common ways.
I think the mirror method works best with magnification lowest, and parallax to infinity.....not sure...been a while.

I didn't get to shoot today because of rain but here's the pic of the RAW and Sightron SIII scope as promised.

Thanks for the picture. I'm debating on FX rings also. Hoping to keep the cross hairs as close to zero. 20 MOA rail should help either way.

Are you referring to the 22 MOA rail that's already on the 1000X or another rail? My apologies if this is a dumb question but I'm just learning about this stuff.

I don't know if this makes sense but wouldn't it be a good feature for scope rings to have a micro adjustment knob? The adjustment on the rear and solid pivot on the front?

Likely they worry about movement over time. The FX rings are kind of a air gun thing, but imagine them on a 50BMG taking that kind of thumping over and over and still not moving.
