I just bought a RRA .223 with 16" barrel. I put a hi-rise RRA cantalever scope mount with a nikko-sterling 4x10 on it, put the bore siter in and when I went to bring it up in elevation, I ran out of adjustment before I got up to the crosshairs. I have the cantilever faceing backwards for the eye relief to fit me. Any help would be appreciated.
-
got a pic?
-
Move the cross hairs full left then full right and count the full number of clicks divide by 2 and adjust to center and try again. Do the same for vertical adjustments; this is what 2 scope companys told me to do and it worked.
-
Sounds odd but ibwill give it a go tomorrow. Thanks! I will put a pic up tomorrow, its the new Wyle-Hyde

Heard of this before, but never encountered it myself. Maybe the ring height is canted to compensate for the wide difference between the bore and scope, and mounting the scope riser backwards is the problem. Measure the distance between the scope ring base and the rail to see if there is any difference between the two rings. :dunno:
I have a couple of the RRA scope mounts, and they worked fine for me....
-
Take the upper off, bolt out, set it on some pillows and look at an object a long ways away through the barrel. Wiggle your head to center object. Then adjust the scope to the object.
A high rise may be too high for the bore siter.

I'm with Len I doubt the bore sighter can compensate for the ring height on an AR. They are over an inch taller than traditional bore to scope height. Though I've always just put a few rounds through at 25yds adjusted and worked out to 100yds never felt the need to bore sight myself.

That's how I've adjusted all my scopes--even the bolt guns. Sandbag it on the bench, open the shop door, sight the bore on something in the neighbor's yard, and set the crosshair on the same spot. It's never far off at the range. I call it "The Poor Man's Boresighter". :chuckle:
-
:yeah: Never did fully trust bore sighters to be consistently accurate. Seen them off as much as 18" at 50'

I know what u mean, the last one I bore sighted was off over 2', but figured with the price and availability I would try & get ot close of possible. I got the idea to put the cantilever on backwards is buddy had his that way & it was spot on. Normally I try to sight threw the barrel, I'm going to try & recenter the adjustments first,but I will check ring height tonight. With for kids,by the time I get them to bed I'm not far behind.lol

Here's a couple more
-
how do you even see through that scope with it that far back? Your scope mounts are backwards, to me.
-
can try shimming rear mount a bit but that won't give you much. some air rifle scope mounts have some adjustment to bring the POI into the scopes adjustment range better. some break barrel air rifles have some barrel slooping and the the scope cannot adjust far enough so you adjust the mount/rings. Many air rifle scopes are very sturdy to withstand the hammering double recoil of air rifle springs. Check out or contact Pyramid Air an air rifle supply distributor on line.
-
I had to put it that far back for the eye relief or use a 30 round clip & flock shoot. Nikko sterling says that ther scopes are tested for air riffles. Guess the ponding is worse then that of .300 calibers. A buddy told me to try & shim it. I'm going to try & recenter the crosshairs first. I appreciate all in putuys thanxs.

Hay Johnvh, I don't know what picture u were looking at, but the stock is collapsed in two of the pics. That may be what u were looking at, every one that has looked threw it says it fits them good, but ya I am half blind too tho, no excuses! lol
-
General rule of thumb is to have your nose touching or as close as possible to the charging handle on an AR style weapon. Looks to me like having the scope mount on backwards would make that tough to do, unless you're pinocchio. :chuckle:

I was comparing it to mine. Mine is close to flush with the rear of the receiver. And I have the same furniture.
-
Just looked at one of my ARs, and the scope is about 1 1/2" back from the charging handle. My mount is a RRA High Rise, but not a radical cantilever mount like yours. My mount is as far back on the picatinny rail as it will go, and is pointed the right way. Turning the mount around and going fully rearwards should put your rings in just about the same place... :dunno:
-
To each there own but no way can that mount be comfortable. Nose to charge handle is general school of thought.

That wouldn't work very well for me. Maybe if I was tall and lanky it might be comfortable, but I'm 5-7, and occasionally I'll shoot with the stock collapsed, when I'm in a hurry, but it feels weird! Even that is too close to be comfortable.
-
Does this scope have a side focus adjustable paralax? If it doesn't then it looks like the scope is mounted wrong, with the elevation adjustment on the side and the windage adjustment on top. :dunno:
-
Well heck that's my problem! I have the scope on backwerds ! Lol It does have a side focus on it, I have the same one on my encore & love it. Out of all the scopes I have tried or have of diffrent brands I will stick to this one in Tue future. Going to try the diffrent ideas in a bit. I will post the out come.
-
Counted the clicks both ways & centered the crosshairs, bore sight hit in the same place. Turned the cantalever around in case it was tapered, bore sighted hit in samebplace & out of elevation, put shims in scope rings, now were talkin! Crosshairs were dead on with the light, I thought hotdog! Took it out and shot it....... Looked for a bigger rock,..... Then a biggenes shotin about 3' high. Took the shims out and adjusted it down a little and got it in the ball park, needs some fine tunein tho. Think I'm going to throw the bore sight away and go back to old school eye down the barrel & fire a few rounds. Guess modern tech isn't always the best. Thanx to everyone for all of there input & help! I was pullin hairs there for a bit. :bdid:
-
bore sighting is a waste of time, just find something 1000yds away, look through the barrel, center the scope on that, start at 25-50yds and youll be on paper.
-
Contrary to what many believe, boresighting will only get you "on the paper" at 25 yards. It is NOT ACCURATE! Only actual shooting will get the gun "dead on". Sometimes even after boresighting, it takes quite a few rounds to dial it in. Then other times I've gotten it "dead on at 100 yards" in as few as 3 shots!
-
I realize that now. Thanx for the input
