View Full Version : Washers Necessary?

02-01-2015, 07:00 PM
So for the very first time I put my scope on by myself. I'm pretty sure I have all the parts because I kept them all in a little baggie. I watched the guy remove it from my other shotgun and it didn't look difficult. Honestly though I don't know if I did it right. It LOOKS right, but it sticks out more than I remember and so do the bits. Wondering if there are some sort of washers that I lost somehow? The fit seemed snug enough, but not too snug that it was obviously missing a part. I don't think I tightened it *too much*...I did it by hand and I'm not the Hulk here. It went from exactly the same gun to exactly the same gun, no mods, only they are different colours. (Remington 870 Express Youth Edition 20 Ga)

Excuse the terminology (or better yet, correct it) I have pictures to show what I'm trying to say.

I gently bonked out the bolt/plug things, put the whole scope apparatus over top of the holes, lined them up, bonked longer bolt things into place and then tightened with an allen key. Ta Da. It seems sturdy, looks about right. Except.

The longer bolt things are sticking out enough that they catch on stuff, and the whole scope apparatus you can see daylight in between it and my gun.

OK. So. Pictures:

Is this right? Am I missing washers or some sort of end caps? Am I just analyzing this a bit too closely? I don't recall it looking like this but ... I never put it on myself last time. :/

You did it right. There's no need for washers on metal that thick. Looks fine to me.

Edit...hold on. In the last pic, the bottom hook of the mount that hooks on the rail doesn't look right. Can you take another closeup of it directly from the back, looking straight down the rail ?

Yeah, that looks like it needs to be removed and put back on.

Probably by:
a) loosening the bottom and top Allen bolts (loosening the top ones should make the rings slide around the scope giving a better/full contact clamp under the rail),
b) holding it in place (perhaps with a couple elastic bands around the sight and shotgun as assistance)
c) light tightening the bottom Allen bolts (to grip the rail)
d) tightening the top Allen bolts (to grip the sight)
e) final tightening.

Are you talking about the scope-to-mount screws or the mount-to-gun screw?

I have the same scope on a Mini 14. Did you know that knob on the side changes the reticle? I just discovered that option myself...
Good eye Den!
Cc you need to loosen the bottom allen head on the rings and drop the rings down over the rail all the way then tighten them back up.
Make sure the top gap of the rings is the same when finished.
The saddle mount bolts are fine. The holes are threaded on both sides of the receiver iirc.
If it was me I'd find acorn nuts for the excess bolts sticking out. Looks like a snag yer clothes hazard to me.

Mount-to-gun screw. They are sticking out, and aren't flush.

So. Terminology - saddle mount is the part over the gun? Rails are what the scope sits on? These are screws even though they only have the threading at the end?

I just learned on Saturday how to sight in my scope, thanks to DOOK. I am so proud of myself bahahahhaha :D

Here are more pictures. Don't laugh at my Hello Kitty footie pajamas. I have cold feet.

Ok. Seeing it from those angles, it looks ok. I think you're good to go.

Bang on with the terminology Cc.

the bit of light showing rail in the first pic is deceiving, the mount job looks fine in the other pics.

Even though there is nothing wrong with having the bolt threads sticking out on the left side, I would look for acorn nuts to cover them... or rather I suggest you look for acorn nuts to cover them. I'd shorten them...

otherwise looks 100%

did you know about the multi reticle knob?

Yes, on all counts. Saddle because it sits on top, with a stirrup hanging down each side.

Mount-to-gun screw. They are sticking out, and aren't flush.
And to my eye, that doesn't look right either.
I don't have an 870, but I think the setup is the same as on my 7600s.
The two screws holding the saddle on replaced two pins, each with a groove 1/8" in from the end?
There are springs in the trigger assembly that ride in those grooves and prevent the pins from sliding out, so you don't have to worry about the guts falling out.

I don't know the make of your mount, but I'd assume that the screws go through and don't actually screw into the mount, but into a threaded bushing, much like a Chicago screw you'd find in leather-work.

If you were to back the screws back out, you should be able to turn the bushings in tight. They may have a groove for a screwdriver, or you might even be able to do it with your fingers. Get them in a bit tighter to the side of the receiver, then put the screw back in and tighten.

Yes! Perhaps a "threaded bushing" could be found then to go on the end? This looks like it would snag on things, and that's why I thought it was wrong. I don't know the make of it either. 1 of Remington 870/870 Express 3.5 Mag 12 20ga. Shotgun Scope Mount [ASIN: B002XW07U6] purchased from SBD Global, Amazon Marketplace Aug 31/12. A quick Google search pulls up a lot of "Sun Optics" stuff if that helps.

I could only tap the screws through to the inside of the saddle mount, so I did need to tighten with the Allen key to make it through to the other side. It is secure feeling (bits won't fall out) I tried backing them out to be flush, but then the scope wobbled.

The pins they replaced looked like they were just a straight pin. I'll have to analyze them when I get home - they did not appear to have a defined "head" and bonked out easily, but then again...I tried my best to replicate what I remembered when it was removed. I approached my gun on the same side the guy did. He removed it very quickly but I watched very carefully.

And yes, BrotherR...I knew that the knob changed the reticle, and how to turn on the red dot to full fricking blast. I just learned the other two knobs COME OFF, and then you adjust it with a screwdriver. I assumed these would be like the other knobs. Windage on the right, elevation on the top. 1 click = 1/4". Repeating so that I remember. I need a manual :(

So long as those screws thread into the left side of the mount, one could make them flush pretty easily with a little file work. Then touch up the ends with a little bluing compound maybe?
