might be a dumb question but with 2 mile shots and extreme ELR becoming more mainstream it seems that even if your scope’s mechanical elevation adjustment is repeatable and there is enough internal adjustment the barrel starts getting in the way.

so people have made custom spacers that look like a high school math book between the action and the scope:



or they spend big bucks on a Tarac which is a really nice piece of kit that gets the job done. (although i still dont understand why some one wants to add more pieces of glass and mirrors to the scope that we all research "which has the best glass")




why dont we just offset the scope like a old M1-D.
barrel wont be in the way.
can still stay behind the rifle with out getting into strange positions.
measure off the center line of the bore, if its 1" to the left of the bore and you sight if in the it always hits 1" to the right compared to the point of aim there should be no worries.

i havnt run out of elevation/barrel obstruction out to 1800, so i might be missing something for these crazy distances.

Sounds logical . Next time you are on a rifle with a decent quality scope , get on target and cover the
front lens of your optic with your hand . Try say a quarter of the available area , then half then 3/4 , it’s
surprising how much area needs to be covered to lose the image .

TacomHQ is making an offset unit and $1500 for the Taco Unit is the cheapest thing in ELR shooting you'll buy.

This is for elevation, an offset mount alone will not fix that and when it comes to ELR shooting why does everyone compromise their fundamentals. They add huge bases with their zeros set to a distance that includes wind and weather, and they can't get a cheek weld.

The Taco Unit at least lets you zero at 100, nice and clean, the mirror has no bearing on the optics of the scope, and it works

Hi,

I think the ELR guys are the least focused on "Best Glass" genre of shooters you can find. The focus per say is on exacting scope functions with precise reticle subtensions. So adding the TARAC prism unit into the mixture is not a problem. ESPECIALLY since it lets you keep your fundamental shooting position in regards to head placement vs trigger feel intact.

A very overlooked issue that arises from some of those crazy high mounts as you have pictured is the mental "feel" of your shooting position. It just does not feel right to have your cheek on such high plane in regards to your trigger finger plane. It is sorta like how a set of stairs feels when they are 1/2" short/high or long/narrow compared to stairs that are within spec.

Sincerely,
Theis

One thing to note here is when we look at the set up in the original post its refers to the extreme innovated set up that a shooter had, not so much what the majority of shooters that are using in the 3000 yard plus zone. The more common scope mount systems being used with or without the Charlie Tarac allow the shooter to still utilize the fundamentals and not sacrifice the shooter platform. In this game the focus on fundamentals still ranks high in order to have any consistency down range. Typical setups will run a 60 to 80 moa picatinny rail or a moa adjustable rail with a scope that has a good amount of travel in adjustments.

If the picture works - here is a typical system being used that still has a solid cheek weld and shooting form that feels comfortable yet has the capability to shoot 3500 + yards - the reason to show this pic is that the scope does not have to be extremely high to function and still be able to dial, adjust and hold to attempt extreme range targets while still in a normal shooting position.

If the shooter understands his equipment and ballistics program well enough they should be able to dial and aim at a extended range target and then dial and aim to impact a 1/4” dot at 100 yards under demand without any issues.

One of this and a NF 7-35 ATACR would do the job.

The Charlie TARAC unit is a much better setup for elevation than that abortion of a setup that Bill Poor has.

As others have mentioned, you sacrifice the most important asset that you should be deploying while shooting, especially in ELR, which is the fundamentals.

“ Methinks thee doth protest too much ....”

Everything pictured below has placed top 3 in KO2M last two years . It would appear , that there are quite
a few shooters having zero issues with their angled optics and raised cheek pieces . Results speak louder
than words .

Looking at the amount of money people put in to ELR setups that specialize them so much that they really shouldn't be shot at normal ranges, the TARAC seems like a decent deal.

On the other hand, it looks like they just used mirrors from 2" telescope diagonals which means about $100 in glass, the rest is the housing, mirror mounts and a pretty healthy dose of profit.

If they were selling in the thousands instead of dozens, they could probably retail for $499 which would be a slam dunk.

Ding ding. The mirrors can be had on the internet for cheap, a 3D printed housing could be had for a couple hours of printing time. I have a prism, the simplicity behind it is awesome but the price is a bit steep. A carbon fiber reinforced plastic print would be much lighter and more economical on price.
