Title: Loc-tite scope mount adapters?
Post by: Tater on July 23, 2013, 08:09:15 PM
Well my scope came in today so I'm off to Cabelas after work. I plan on putting Loctite on the rings right away, would you guys put some on these adapters as well?

Here is the scope I'm picking up:  http://www.cabelas.com/product/Shooting/Optics/Red-Dots-Lasers|/pc/104792580/c/104752080/sc/104526180/Bushnell174-Trophy-Multi-Reticle-Red-Dot-Scope/748368.uts?destination=%2Fcatalog%2Fbrowse%2Fred-dots-lasers%2F_%2FN-1100252%2B10000049%2FNe-10000049%3FWTz_l%3DUnknown%253Bcat104792580%253Bcat104752080%26WTz_st%3DGuidedNav%26WTz_stype%3DGNU&WTz_l=Unknown%3Bcat104792580%3Bcat104752080%3Bcat104526180 (http://www.cabelas.com/product/Shooting/Optics/Red-Dots-Lasers%7C/pc/104792580/c/104752080/sc/104526180/Bushnell174-Trophy-Multi-Reticle-Red-Dot-Scope/748368.uts?destination=%2Fcatalog%2Fbrowse%2Fred-dots-lasers%2F_%2FN-1100252%2B10000049%2FNe-10000049%3FWTz_l%3DUnknown%253Bcat104792580%253Bcat104752080%26WTz_st%3DGuidedNav%26WTz_stype%3DGNU&WTz_l=Unknown%3Bcat104792580%3Bcat104752080%3Bcat104526180)

Tater... what gun are you mounting this on, co2? pumper? PCP? if so, very little Loctite needed if any  ???

No need to loc-tite the adapter no screws to lock the scope will keep it tight. Just wondering why your doing it to the scope before you even know if you need to?

It will be going on my 1377.  I guess I just thought I'd play it safe using Loctite ahead of time, but it sounds like I don't need to.

Tater, nothing wrong with a small dab of blue loctite on the screws... a little security  ;)

Post by: Tater on July 23, 2013, 11:28:28 PM
Thanks sir.
My POI with old BSA red dot would drift every few days, but since I loctited, it's been fine. Now to just remove it and try the two new dots to compare them. I'll be returning one of them.

Rather than start a new thread, I thought I'd add this here. As you can see in the pictures below, it looks like there are issues. The bottom screws on the rings are right in the way of where the adapter would sit. Since I've never used an adapter before, I hope there's something I'm missing because new rings aren't in the budget right now.

Edit to add: The scope has a significant green tint when looking through it. Could this be normal? My BSA is totally clear.

That adapter has the slot in it that should fit around that screw.  Should work fine and I wouldn't try to put locktite on the adapter no need.

Post by: cherokeesteve on July 24, 2013, 03:01:15 AM
The screw in the bottom of the rings should fit inside the slot on the top of the adaptor.  I've got those adaptors on a couple of my guns. The tightening of the screw on the bottom of the rings squeezes the adapter and I haven't used loktite on mine. I ditch the set screw that sticks up through the adapter, I believe it's for high recoil guns, prevents movement.

Thanks BGmcee, I've made a fool of myself here again.
Seeing as the slot is centered on the adapters, it give me no flexibility to mount the scope forward of the area to load a pellet. It will have to be mounted over the opening. I'll have to try it out to see if there's room to load it, it's gonna sit pretty low though.

Thanks for the info on the set screw Steve. I'd rather not scratch up the breech with it if it seems to hold tight, so I'll try it without.
Title: Re: Loc-tite scope mount adapters?
Post by: Fronzdan on July 24, 2013, 03:24:15 AM
Yeah that dot sight you have needs to straddle the breech opening.  It will be pretty low, cutting down on your access.  You might be able to roll a pellet over the edge with your finger, but medium height rings would be better.

These would work for you...

You don't need the adapters with these...save em for another build.
Title: Re: Loc-tite scope mount adapters?
Post by: Tater on July 24, 2013, 03:53:41 AM
I might have to resort to that at some point Fronzdan. I went and installed it, it looks like it wouldn't be too tough to load but I have to try it tomorrow, still haven't eaten dinner yet.

Cool, I think I'll be able to load it too. It's favorite pellet (Daisy HP   :o) requires me to have to push the pellet past the breech port with a toothpick. Next time the breech is off, I smooth up the port as mentioned in a thread here.

Post by: Fronzdan on July 24, 2013, 06:21:17 AM
Oh heck that's perfect.  From the pic of the scope alone it looked like it would be too low.  That's right where you want it!
Title: Re: Loc-tite scope mount adapters?
Post by: Tater on July 24, 2013, 06:29:24 AM
And the dot is TINY. Even the plain crosshairs are really thin. I might even go with the crosshairs® even though my intention was a tiny dot. I'll try 'em both tomorrow or Thurs.
Chipmunks, Hosps,and paper targets beware.....
Title: Re: Loc-tite scope mount adapters?
Post by: Fronzdan on July 24, 2013, 06:09:51 PM
Yeah for the sights that I have with the multiple reticle/dot, I prefer one of the crosshairs with the dot in the center.  It's much easier to see and works great for bullseyes.
Title: Re: Loc-tite scope mount adapters?
Post by: Tater on July 25, 2013, 05:28:08 AM
Update:
I made sure the rings/adapter/scope were all lined up and tightened everything down. I had minimal time to shoot and only took a few shots from 12'. Trying two different reticules, all shots were 5" low and 5" to the right.
I looked it over thoroughly under bright lighting and nothing seem canted or tilted at all. My wife looked it over very closely too. Could it be the adapter/rings combo? I'm using the rings that came with the scope so I know they are cheapies. Do you guys think just remounting it might give different results or are would better rings be needed? Anyone have a Bushnell red dot and have luck with the stock rings?
Title: Re: Loc-tite scope mount adapters?
Post by: breakfastchef on July 25, 2013, 05:39:12 AM
I assume you made windage and elevation adjustments to try and center the shots. I also assume you know the pistol can shoot on target with a different type sight. I am sure you have checked that all your screws are tights and the barrel is inline with the compression tube.


I have both a Millett and Ultradot with similar stock rings as the Bushnell and both are solidly mounted and very accurate.

I actually didn't try/have time to adjust windage and elevation. At 12' from the target, I figured I'd run out of clicks to have to move the POI 5". The pistol was shooting perfectly accurate with a cheap BSA 3 MOA red dot right before removing it and adding the Bushnell. I upgraded only to have the smaller dot and crosshairs.

Seems like a lot, not unheard of though. Make sure those adapters are seated properly.

Me and my wife looked very closely from every angle and nothing seemed "off" at all. I guess I'll try remounting it tonight. If that doesn't work I guess I'll have to look at new rings.   :(

Jerry,
Assuming you have both rings and both adapters oriented the same direction:
One thing I have done with regular scopes before when it was way off after the first few shots, is to center the reticle. Turn one of the adjustment knobs all the way in one direction until you feel resistance, and then turn it back all the way the other way while counting the clicks until it again stops turning.  Then turn it back half the number of total clicks.  Repeat with the other adjustment. IE, if you did elevation first, repeat with the windage adjustment.
Theoretically, that should center the dot but depending on how well it was engineered and constructed inside, it may not.  Just in case, count the clicks at the beginning in case you need to return to the original setting.
Hope you can get it sighted in.
Cheers,

Thanks, I will try that too. Would a brand new scope come with the adjustment knobs not in the middle of the range?
I'll switch the front rings with the back as well.

Seriously, why look for a problem that may not even exist. Three shots at 12' does not tell you anything except that your pellets were off low and to the side by 5". [size=78%]Just zero the scope.[/size][/size][size=78%] [/size]

That's what you are checking for.  It may depend on which knucklehead was on that part of the assembly line that day and if QC caught it or not.  :)

Tater, I'm guessing you had another sight mounted on the stock dovetails?  Were the rings also lower?

Keep in mind that the dovetails (theoretically) should be in  aligment with the barrel in both X and Y centerlines. Also, with the weaver adaptor inserted and higher rings you are now "stacking" height above centerline and any error or alignment issues in dovetail to barrel are amplified as you get further away from the dovetail grooves.

Also, try the new scope and rings on another gun if you can before you tear the rings/scope assembly down, and... you need at LEAST 10 meters to have a valid test of your scope. 12 feet ain't gonna work.

Last, 5 inches is a ton of adjustment and the reticle may not even adjust that far with out bottoming and loosening the reticle mounts/springs (bad, very bad)

This is correct.  If you are going to try to center the dot/reticle (as per my previous post), be very careful.  When you get to the end of adjustment, stop when you feel any resistance.

There was another scope on it and I don't believe the rings were high. It was a cheapy BSa dot. I'll try to find a picture of it.
Title: Re: Loc-tite scope mount adapters?
Post by: BDS on July 25, 2013, 09:03:18 PM
If it's the BSA I'm thinking of, it has a built in clamp that you can use on 11mm dovetail or on weaver mount, that sight sits pretty low compared to your new set up.

I had to work from home after work and didn't have much time again to shoot, but I will have much more tomorrow. I counted the elevation clicks in  each direction and it turns out it was off. 57 clicks overall and it was set at 37 from one end. I centered that at 29 clicks, then remounted the scope switching the front and back rings. Held off on the horizontal adjustment for now.

After several test shots, it was centered right on but still 4-5" low. So remounting it fix the horizontal but the elevation was still off. Next I moved up 7 clicks but at that close range, the POI only moved up a half inch or so. 7 more clicks yielded the same, so it was clear I'd run out of range. I had to stop to eat and it's getting late so I'm done for now and not sure what to do with it tomorrow.   ???

I guess I'll just return the thing unless anyone has an idea. I really don't want to shim it, I wish I had brought it in the work today so I could return it on my way home.   >:(

The one time I had this issue with a 13xx I picked up a pair of adjustable rings.  I don't like shimming either. They worked great. Nice and solid after adjusting the rear height and tightening everything down. I can't remember where I picked them up but I'll link it if I find out.

Just remounted it again for the forth time and same issue.  :( It's only 2" low now, but at 10-12'?   :o
I guess I'll be returning it. I shouldn't have to by adjustable rings for a brand new scope. Nicer rings would be great but they're not in the budget. Plus I can only shoot inside the house so the gun never get roughed up, it's babied.
The stock rings should at least get me on the target at close range. My previous cheap scope worked fine so I doubt the breech could be off at all.
