Title: moving your scope
Post by: littlebuf on December 30, 2009, 07:49:04 PM: i decided i needed a little more eye relief on my AR so i slid the scope forward about 3/4 of a inch. this is a flat top with the weaver style mount so what i did was loosen just the ring on the front and just the base on the back, moved it up a couple notches and tightened every thing back down . you guys think this threw off my scope at all?

I'm bettin that your POA vs POI will be off a bit.

he also moved the whole thing to a different spot on the rail though...thats a little different than taking it off and putting it back on in the same spot.

True true! I'll bet it's going to shoot well off POA. What was said earlier??? MOC? (Coyote)?

Is it a POS or a good scope? :dunno:
Title: Re: moving your scope
Post by: littlebuf on December 31, 2009, 04:31:56 PM: its a good scope and it was off by a country mile! i was surprised when i went to check i figured it would be off a little and a couple of minor adjustments would put me right back. well at 100 yards i wasn't even on paper, at 25 i was barely on paper. it really surprised me how far off it was. i just barely loosened the ring and opposite base enough to slide it up. thought it would be closer. but that's why we always make sure.

Post by: carpsniperg2 on December 31, 2009, 04:35:20 PM: yep, not worth taking a gun, you don't know were it is shooting. into the field glad you shot it.
Title: Re: moving your scope
Post by: littlebuf on December 31, 2009, 05:05:19 PM: oh i never considered taking it into the field before shooting it i just didn't anticipate having to go through the whole sighting in process again. had her sighted in in about 9 shots then i just tuned it

its a good scope and it was off by a country mile!

-And everyone's mileage may vary. I had to remove a scope from my 10-22 this year when I noticed the forward rail screw came loose. I left the rings tight on the scope and removed the ring to rail screws carefully counting the turns to just get them off the rail. I locktighted and tightened the screw, and returned the ring bases to original positions. Tightening the scews the same revolutions until tight. Test firing... It shot 2" to the right @50yds when it had been zero'd at 50yds before that. That's with everything going back to original locations. I am not suprised that your gun was off target at all.

Post by: littlebuf on January 01, 2010, 09:54:54 PM: i wasn't surprised it was off, i was surprised how far off it was. only reason for the thread is because i was wondering how off it would be after i moved it and i tend to post whats bouncing around in my head on here. sometimes that's a good thing and some times that's a "oh my god this guys a nut job wacko extremest thing" :dunno:
Title: Re: moving your scope
Post by: JackOfAllTrades on January 01, 2010, 11:15:43 PM: Well, the crazy thing is... A friend and I pulled a scope off once. Out of the rings. Rings off the bases. Put it all back together after honing a new set of rings in place. It shot exactly where it did before we pulled it apart. That's only happed once to me. Total exception to the rule.

Off the paper at 50yds is a little out of the norm after puttin a previously zero'd scope back on is a stretch though. (although you did completely move the mount positions.) I almost think there could be a little torque on the tubes by the rings not being true. Or that the rail positions are not milled exactly the same at each notch. I use a 1" piece of stainless rod with 600grit wet/dry and hone rings to make sure they're straight and will not bend a scope. You'd be surprised at how out of alignment many ring installations are.
