The sale posting tends to get buried and I'd like to solicit feedback from those who have received their sets already but don't want to keep bumping that. Sounds like some folks are just doing trial and error with the set, which is fine it provides alot of height adjustment potential. But I'm genuinely curious and wanting to confirm the labeled measurements are lining up fairly close on others scopes.

Classified link for shims

For those that have received their sets and tried to match up the labeled shim stack height versus what they measured was needed on their scopes (mils from the scope zero till the turret was dialed all the way down to the minimum travel) are things matching up well?

For those that have ordered the 6x version with intention of trying them in the 3-15 gen 1 scope what is the fitment verdict?

I appreciate any feedback, thanks.



A little more explanation since some said they didn't understand my initial directions.

ORANGE shims are for the 3-9x42 Gen 1:
The turret cap has a tall dead space in it that needs to be filled up before a shim would even start to engage as a zero stop (versus the turret bottoming out at its end of travel). The way I decided to tackle this set to not have fragile thin shims for the adjustments was to make a base shim that was shorter than needed (I provided two bases that were 9.5 and 10 mils too short respectively, hence the -10 and -9.5 labels) and then a series of shims from 10mil thru 20mils thick. The set can result in hitting a stop height in approximately .5mil increments across the ~25mil of travel the scope has.

The (BASE -9.5) shim combined with a (20) mil shim would result in stop that is 10.5mils above where the turret is completely bottomed out, or another way to look at it would be 2 full revolutions and .5mil more from the bottom of travel.

Your rifle would need 17mil of shims if you dialed down from your zero 3 full revolutions plus 2 more mils.
(BASE -10) + (10) + (17) shims would result in 17mils. If you wanted the stop past your zero a bit further you could use the (BASE -9.5) or (16) shims instead to move it back another .5mil or 1mil.


Green shims are for the gen 1 6x42 mil:
(These will supposedly fit all the gen 1 fixed power the same and should fit the 3-15 turrents but I am seeking confirmation on both fitment and how well the labeled shims match the needed height since the travel of that scope is a little different on their specs)
The fixed power scopes didn't have as much of a dead space in the turret cap to fill up so for these ones I decided to make the base shims fill the cap fully and provide the fine adjustments from .5mil thru 5mil and provided a 5, 10, 15, 20 mil shim for coarse adjustments to cover the ~40mil of travel the scope has.

The (BASE +4.5) shim combined with a (20) mil shim would result in stop that is 24.5mils above where the turret is completely bottomed out, or another way to look at it would be 4 full revolutions and 4.5mil more from the bottom of travel (almost 5revolutions).

Your rifle would need 17mil of shims if you dialed down from your zero 3 full revolutions plus 2 more mils.
(BASE +2) + (15) shims would result in 17mils. If you wanted the stop past your zero a bit further you could use the (BASE +1.5) or (BASE +1) shims instead to move it back another .5mil or 1mil.

QUESTIONS OR CLARIFICATIONS?

I'm reposting this detailed feedback @TheM1DoesMyTalking added in the classifieds thread. I appreciate the confirmation!


This is a great shim kit. I appreciated the easy transaction and quick shipping, @pods8 (Rugged Stitching)

I have a SWFA 3-9X that had 12 mils of travel from my zero to where the turret bottoms out. I started with the base-10, 10, and 12.

This worked, but I could go about .5 mil past my zero. The second combination I tried was perfect: base-9.5, 10 and 13.

After checking zero at 100 I practiced at 300 and 500 yards today and I really liked having the zero stop there to give feedback as I was approaching and reaching zero. These shims are a home run upgrade for this optic.
 
Any feedback like above from the guys that ordered the 6x? What about those who were going to try them in the 3-15, can you confirm they fit and if the measurements like up like they do on my 6x?

@Sierra Hunter iirc you had ordered a set of the 6x mil to try in the 3-15MOA knowing the labels wouldn't correlate but did they otherwise fit and allow you to get a zero stop set up?
 
Do we know if they work in the 3-15?
They fit, the reference height may be off since they were designed based off the fixed series but within the stack the reference heights would be relative so you can walk in a height still.

Overall the set of shims can make up a lot of variation even if just doing trial and error combos.
 
I own a 3-9, 3-15 and 5-20 SWFA’s.

That being said, is there a shim setup for the 5-20 series as well? If so, I’m interested in 3 sets of shims for the above scopes.

No 5-20 shims currently, I don’t have one. If someone loaned me one I can make some up but for the moment it’s just the 3-9 orange set and the green set for the fixed series (which can also be used in the 3-15 but the reference height will be off).

If you’re interested and willing, I’ll send you my 5-20 for you to measure for a set of shims for the 5-20.

I’ll buy the 3-9 & 3-15 shim kits you have currently. I’d like all my SWFA’s to be uniform
 
I don’t have a 5-20, but I do have a 10xHD. The turrets on it are larger diameter than the turrets on the 3-9s.
