How to Mount a Scope on Your M14/M1A/M305 PR or SR or DMR Rig and Keep it Level


On one of my previous posts, I spoke about installing a CASM Mount on your M14/M305/M1A/Garand rifle. Now let's chat about ONE very common mistake and that's leveling your reticle, and keeping it level, but on the CHEAP.... This technique will work for ANY scope with flat surfaces (most of them on the flat top of the elevation knob). :cool:

Many rookie scope mounters find that keeping your scope reticle level as you tighten down both left/portside and right/starboard screws, they may cause the reticle to shift/slant/tilt over to the left (like Turdeau) or right (like Rona Ambrose... whom I have a crush on... okay, maybe Calgary's Michelle Rempel...) :nest:


Hopefully you are more comfortable (skill set, experience, tool inventory) with doing scope mounting that most rookies, so that's where I'm gonna start. If you are very experienced mounting scopes, then I hope to raise the level (great pun, get it ? :eek: ) of your skill set. ha ha ha :evil:



Materials needed:

* your scope
* scope rings of your choice
* your rifle already mounted in it's stock, clamped in bench vise, hopefully not on a slanted floor :eek:
* Reliable screwdriver with correct sized/shaped bits (Allen, Torx, Flat blade, etc)

And finally:

A string level... I bought this one at Home Depot for $5.00 give or take (didn't I say CHEAP??). I told you guys I've 30 years in the classroom as a professional edumakator so I'm a cheap bugger.... :cool:





This baby happens to balance nicely on my Bushnell 10 x 40mm Mildot scope that I bought off the EE Forum from a super CGNutter in SK. :wave: Yep, it's sitting nicely on top of the elevation knob. I've also done this with my Leupold Vari-X3 4.5 x 14 x 50mm hunting scope that sits on my Winnie Model 70 .308, all Leupold's elevation knobs have a tiny flat circular surface, and this light and small sting level fits the top surface. :cool:


Okay first thing you gotta do is space out your rings on the base (I'm assuming you know how to do that). If you need help doing this, we gotta talk. I'm also assuming you know how to adjust your eye relief to obtain a clear image (I like to use a white freezer door in my basement) without any black donuts. If you don't know how to do this, re-consider reading this post, it might be a tad advanced for you.

Now that you have your ring spacing and eye relationship and field of view established you are likely ready to start screwing down the top hemisphere of the rings. Go ahead and lightly install them.

Now place the string level on top of the elevation knob like this:





Begin torquing down one side BUT ensure that bubble remains level and balanced between the stadia lines... if it tilts (bubble moves to one side), back off the screwdriver. Start again, from level and light tension on that screw. Tighten down just before that bubble shifts.

NOW, do the other side... the bubble should not shift. If it does , back off , and switch sides.

What you are doing is ensuring that the screw(s) from side to side do not tighten so much as to CANT that reticle. :(

THAT is the key to ensuring a flat reticle as best you can on the CHEAP ($5 sting level at Home Depot) or what ever hardware store you frequent/support/shop at. :dancingbanana:

Now go and do the other ring the same way. Ensure that bubble remains level. If it shifts, they you know that screw tensioning process is shifting the level of the reticle. Start again and screw down JUST Enough to avoid tilting that bubble.


Questions?


I'm done....




Many of you experts / experienced shooters out there likely have your OWN techniques and skill set doing this. My point is a $5 level can sure make life very easy and ensure your reticle is level (for the most part)... :nest:

Hope this helps your game! :wave:

Train like you compete, then compete like you train.... :evil:


If you learned something from this post, have a look at my dealer forum where I store the rest of them blogs on M14 tweaks and tips....

Then again, many of you following me knew this already.... hey, it's all good! V:I:

This is all very good advise but please make sure that the rifle's action is level first. If you use a scope base with a level surface, put the level on it before mounting the upper scope ring halves and level the rifle in the vise. The side to side level is the important one here just like the scope level. Then proceed as described by Hungry.
 
AND...make sure that the reticle is true to the turrets/caps...or vice versa...

Some inexpensive scopes have turrets that are cocked off to one side or the other if the crosshairs are perfectly level. I've owned several older
Weavers (steel tubes) with that affliction...and, oddly, a couple of 1990's-vintage Leupolds that came that way from new. If you suspect that this might be an issue...or maybe even if you don't but you're just a bit OCD...it's easy to check the level of the crosshairs with a plumb line after completing the mounting procedure as outlined in this thread. Just holding the unmounted scope up to your eye and comparing the turrets to the crosshairs will give you a pretty good idea right up front; best to do this on the lowest magnification setting.
 
Now a days a smart phone can be used a level. Installing my latest scope I put my phone on the rail and noted what degree it was sitting at. I then matched the angle when I put the scope in the rings by laying the phone on the top turret. Pretty accurate down to 0.1 of a degree!
