Quick Tip: Common Scope-Mounting Mistakes To Avoid

[@CalebSavant]

Nope, we did not cover lapping scope rings in this one, the reason is because it is typically not an issue for you average user, by average we are referring to the vast majority of rifle shooter. Lapping rings is important for precision rifle shooting and it deserves it's own video.

[@Alex325-z5l]

Hey Caleb, looks like you need to flip your front sight on that Armalite Rifle you have there.

[@dodgersfnshepard8673]

Do a video about keeping/cleaning lenses

[@halfinchholes88]

I lap nearly every scope, but if not, I still use the lapping bar to verify alignment issues before torqueing the caps down. A little Dykem Hi-Spot Blue can show it all. Normally, I marry scopes to a specific rifle, and never move them between rifles. Saves a lot of troubles and headaches.

[@MF_UNDERTOW]

It’s important to push the rings or mounts forward (towards the muzzle) inside the pic rail notches before tightening them down so that they remain snug under recoil.

[@montgomeryfitzpatrick473]

First time I put a $40 scope on a high fps air rifle I failed to do this and thought it was the cheap scope not holding zero, just turns out I just hadnt learned how to mount on pic rail yet

[@danschmitt2490]

​@@montgomeryfitzpatrick473also you need to make sure the scope is capable of handling the double recoil and high frequency vibrations of a piston air rifle if it is that style... Piston air rifles will wreck a lot of scopes... I have shot one out on mine... 😬 Was thinking any old center fire rifle scope would handle it but... I guess not.. now as we progress with tech... Alot of modern scopes will handle it.. but not all of them I figured that out!! Scope was 400.00 and now it's a paper weight... Everything mounted correctly... I mount all of my own equipment.. first time that's ever happened.. don't ever buy barska and throw it on an air rifle!! 😂

[@goosecouple]

Tip: Inspect the inner radius of the scope rings. Run your finger along the radius and feel for surface irregularities. Sometimes the radius are irregular due to machining defect. Don't mistakenly assume Made in USA to mean "defect-free".

[@LuvBorderCollies]

Good point.!! I learned the hard way to feel the radius on every brand of scope ring.

[@michaelb4528]

The E Coat or A Coat finish can also have runs like paint inside the rings that should be lapped out

[@aransasfirearms]

You should always make sure your rings or mount are pushed forward against the slot before torquing to spec, imho......

Thank you so very much for this. I checked my scope and rings while Caleb was talking and sure enough they were making contact with the turrets both front and back. I had no clue that them touching could make such a difference. I can't wait to get out to the range after work tomorrow to see the improvements. Thank you much gentlemen.

[@2CODO1963]

I don't know if anybody mentioned this, but if you are going to use a torque wrench, it is essential to return the setting to zero before setting the wrench to a different torque value. Do this every time you change the setting and every time you are done using the wrench

[@blackhawk7r221]

I’ll add a few that our shop sees VERY often: 1- the ring to receiver screws and ring screws themselves need to all be brought down together gently in steps to gain perfect alignment and seating. 2-average AR scope needs to be 1-1/4” to 1-1/2”. 3- Do not use separate rings and bridge a receiver to a handguard 4- a solid one piece mount setup is always better, IF your bolt action allows. AR’s no problem. 5- Interface problems between Weaver and Picatinny. 6-scope mounted too high causing a gap in cheek to stock contact. 7- clueless as to how to achieve proper cheek to stock weld, and clueless as to how to adjusting their body to properly shoulder the rifle. 8- believe it or not, placing the optic where it looks coolest.

@Hewhoremains420 What kind of rifle do you need to scope?

[@Jammaster1972]

Nobody talked about LocTite ????

[@blackhawk7r221]

@@Jammaster1972 We don’t recommend Loctite. It’s not so much that screws back off, but rather the aluminum rings, aluminum mounts, and aluminum rails all expand and contract going from indoor temp to outdoor temp, to hot barrel warmth, then cold outdoors temp, then back to a warm house. Aluminum is one hell of a good heat conductor, so expansion and contraction causes slight looseness over time, so setting the screws at the proper torque with Loctite will cause issues later when it’s time to retorque, which you WILL have to do with aluminum. Allen head cap screws round off easy enough as it is. Now if you have steel rings on steel mounts torqued properly, you’re good, Loctite or not.

[@Jammaster1972]

@@blackhawk7r221 I hear what you're saying. However, my experience with LocTite has been such that I've never rounded metal loosening them. Have you experienced this?

[@Grizzleback07]

​@@blackhawk7r221Weird....Locktite is used on automotive parts, many of which experience extreme thermocycling, and have not failed.

742 - been there and so funny that you mentioned it! 50 years ago, I was ready to use my Bicentienial 742 30-06 as a boat anchor as it simply would not hold a scope sighting... Scope rings may not need torquing, but the 742 forearm screw needs to be tightened by the hulk with a big ass screw driver! Thank you for your content fellas!

[@goodnewseverybody739]

Yeah that’s the only time I need to screw in the handle on torque wrench. My fore end had such a bad fit I tossed the nylon spacer and bedded it front and back- much better. As for poi shift, if everything is good up top with the scope, remove the 3/4 nut off the recoil lug, remove the barrel and check the treads on the stud. See if the nut runs down it good past the point it would tighten the barrel, I had to use a thread file cause mine were cut shallow toward the bottom. Clean off loctite throughly. I had to grind a wrench to get that nut off. After I did these 2 things it took a rifle that was shooting dirt to a 2” rifle😊.

[@allenseal5551]

[@johncmitchell4941]

1) I like 2-screw vs 4 or 6-screw rings with older, lighter glass. To keep a scope from slipping I'll dust them inside with powdered rosin. I learned this when still shooting gas piston vs PCP airguns. 2) Not for QDs but on some 1" setups I'll put a TGP bar into the rings before finally tightening them to the rail, then swap out the bar for the scope. This is quick & easy and why I don't feel a need to lap rings. btw, great video.

[@kevinyoung8651]

Suggestion; a video on the value of a good torque wrench. I bought one a couple years ago and I had no idea what a jack legged mess I had been making, especially on scope mounting but even worse was action screws. The difference is night and day.

[@briskyoungploughboy]

Some older rifles have hand-ground receiver tops. Misalignment of scope-bases is almost inevitable. Best way to avoid bending your scope-tube is to use the Burris Signature rings- the ones with the spherical nylon inserts. Or you can spend hours lapping your rings with a 1" steel bar and auto valve grinding paste.

[@emogowl]

Scope mounting is one of these areas where every tyre kicker in a club will have an opinion. Nice to watch/listen to experts, thank you

[@milboltnut]

Great tips! I just ordered a rail base last night to replace my two piece weaver bases. The rings were to close to the bell and parallex dial! Accuracy was good but occasionally went somewhere, and l believe the rings were pinching internally

Very valuable information guys!!! ....and the way you described common scope mounting problems with easy to understand examples was much appreciated. Every beginner shooter should be watching all your videos!!!!

[@friskywildthing]

Great info, gentlemen! I didn't realize how detrimental proper placement of scope rings on the scope barrel can be. Thank you. Some of the mistakes you mentioned I've already made with a Vortex Venom 5-25x56 I recently purchased. The 34mm Vortex Pro (medium height) scope rings I bought causes the front of the scope to contact the rifle barrel when the lens cap's in place. Luckily I haven't tightened anything down, so I can exchange the rings for the correct height.

[@unbereafigendlic8414]

Vibra-tite instead of Loctite for removing scopes if you need to. It's designed for guns and you can reuse what you've already applied instead of cleaning it off and reapplying it.

[@maxstueven1965]

Make sure you are careful the torque settings can change if you are using any compound that was not factory applied to the screws. Torque settings will be different for wet vs dry. This is why I follow the manufacturers instructions.

[@chrisfournier6144]

Vibra-tite is a great product!

[@xenomorph1317]

You also have scope ring caps with three screws on top, so what torque do u use then?

Sound advice, gentlemen, especially with all the different approaches, methods, and ideas out there now.

[@syork24]

Excellent advice. Your video explained why I have been having problems getting my scope zero'ed. The first thing I need to do is get a new AR scope mount.

[@kcMan7938]

I am a believer in using the wheeler scope ring lapping tool on all scope rings . It improves the fit and increases more contact surface for rings to hold onto scope. I consider it a necessary step when mounting a new scope .

[@tomforeman4976]

When I first mount anything especially scopes I use liquid white out in the little squeeze bottle with the metal tip to put a fine dot on each screw to check for proper tightness at a glance. After a box or so doubel check with torque wrench and use engine decreased to clean off white out and trust your work until it changes on patters.

[@TheFlyingZulu]

Some things I learned when mounting my first scope and that was not mentioned in the video well... Make sure the RETICLE and action of the gun is level before and after tightening down a scope. This will make zeroing a rifle much more precise and attainable. I emphasise RETICLE because the scope housing could be slightly off from the reticle. Some people just toss a level on the top flat part of the scope and go with that... nope. Put a level on the rifle scope rail mounts and then shine a light through the scope and it'll project the reticle onto the wall. Then use a hanging line to line up the vertible reticle with the line on the wall. This is called using a plumb bob. The rings should also be pushed all the way FORWARD in the rail slots before tightening. If the rings are reward in the slots the recoil could make the rings work forward and throw off your zero.

[@JohnDoeEagle1]

Unless you are using a $30 Walmart scope the housing and caps will be perfectly square and level. They are CNC machined in this day in age. "This" isn't a Plumb Bob either. It's a torpedo shaped object that you hang in the dead center of a door/window etc etc from a string from above. When it's perfectly plumb using gravity the point of the torpedo will be pointing to the exact center on the bottom and you can start nailing. Have to find exact center on both the top and bottom for it to work.

[@davidunderwood3605]

Very good video. You forgot the one piece scope mounts, they can be turned around backwards. Some makes no difference other than looking non conventional but those that offer that extra 20+ moa is another way to not getting good groups if you can adjust to get on paper

[@Casper0844]

Also its important to use the same material scope base as the scope ring, right? Mounting tip: front load the mount i.e. push it forward. That ensures solid engagement with the rail under recoil and more importantly allows repeatable zero if you run a QD and swap optics

[@hopewilliams6705]

Getting ready to mount one soon great information and timing

[@jamesdaniel6081]

Tip: Level your scope with/using the reticle, not the elevation cap.

[@yeejay6396]

Interesting..

[@JohnDoeEagle1]

Have to use the elevation cap to place the level on to get the crosshairs level in addition to a level mounted on your barrel or Pic 1913 rail. Start with the barrel or rail being level first. Once it is.... level the crosshairs to that level and itself using BOTH levels together. You will have perfect alignment if you do. I use the Wheeler Engineering kit for all my scopes. It has all the pieces included.

[@JohnDoeEagle1]

@Hewhoremains420 Too close to the objective or front of the scope.

[@leewilkinson6372]

So, I watched a video where the guy shined a light through the scope so that the reticle appeared on a wall. He then leveled the receiver with spirit level and aligned the scope by using a plumb Bob on the vertical cross hair because a plumb Bob is "hands free" Seems like it would work really well, but needs a bit of space and a clean wall to work. Neither of which I have in my workspace unfortunately. I'd like to try it though.

[@ethanterry3370]

Small tip: Level the vise, then the rifle to the vise, then the scope to the rifle to the vise. You can buy leveling kits, but there are magnetic line levels out there that will work too, for like a couple bucks a pop. Remove the elevation turret cap to place the level, since the cap is just one more layer that will throw off true level.

[@lanceschul]

Good stuff. How about a debate on reticle leveling? I’ve determined that the plumb bob method works the best for me. What do you say?

[@Steaknjake.45]

Do what works, right? Lots of scopes are flat under the turret and a quality rail is flat. So I’ve had good luck with using a piece of steel to align those surfaces. There are alignment tools that use two wedges to do the same thing.

@@Steaknjake.45 for sure. Feeler gauges work too. I have tried the wedges but when I get things snuggled up they tend to get stuck…

In the case of the scope being a little loose in the rings, I've seen a small piece of friction material like 320 grit "wet or dry" sandpaper cut into a strip, and placed under the scope. It gives the rings the needed "grip" onto the tube. Not the best solution but it works for plinking guns, etc.

The rear ring on the bolt gun is “on the bridge” and not “on the island.” Is that best practice?

[@LJK301]

Because there's always a bit of loose tolerance between the mounting points on a rifle (whatever standard that has an integrated recoil lug) and the rings, I've had a habit of pushing the scope rings forward whenever I initially tighten them to place. Since the rifle moves backwards when firing, everything "hanging" on the gun will tend to want to stay in place, effectively pushing it forwards on the gun. If the rings are already at their forward most position, they can't move in place. Don't know if this practically makes a difference but it's at least a little bit of peace of mind. Also applies the other way around. If I have a front grip on my AR-15, I'll pull it backwards before tightening it, since I'm going to be pulling on it fairly aggressively when shooting.

The biggest mistake I see people make in mounting a scope to their rifle is letting Sportsman's Warehouse charge them $25 do the job with laser bore sighting 😜 Can't keep track of how many "hunters" I've seen at the range with a new set-up and they aren't even on paper at 100 yrds. They say it's a new set-up with Sportsman's doing the work. Even though they bought the rifle and scope from Sportsman's they still get charged $25 for mounting and laser bore sighting. Many times even the scope is not squared-up to the axis of the bore. So because at that point I feel sorry for them I'll pull the bolt and do a quick by-eye bore sight which usually results in the first shot being within a few inches of the bulls-eye.

That look in Caleb's eyes at the mention of Loctite...

Some good simple tips here.

The scope mounted on Lee Harvey Oswald’s scope was loose and flappy (per this video it was reason #2 for inaccurate rifles), yet we’re told he made those shots with that rifle..

[@CutlassOutdoors]

Another common problem is adhesives like Loctite getting between the rings and the scope’s body tube, preventing the rings from properly gripping the body tube.

[@woohoo2you966]

How much of a gap between the scope and the rifle (and things mounted to it) are acceptable? For example, I have an AR with a LPVO, mounted below the eye piece is a folded down rear BUIS. There is about 1 - 2 credit card's worth of space between the two. No touching but is CLOSE. (Look's similar in setup to Steve's son's AR in the video)

If a piece of card stock fits without interference, it's good.

Me too I've been mountain scopes forever and everybody's always been very happy with what I've done for him

A guy just did a video show large distance between bore and scope. I'll have to see if I can find it.

It's MDT who made the videi

I just use Burris signature rings..that takes care of alignment

[@jeffreyMagnum460]

I always use medium thread locking compound on the fasteners.
