Aimpoint Micro H & T Series – Toughest CQB Red Dot

The Aimpoint Micro H1/2 & T1/2 are probably still the king of the micro red dot market for its superior durability, battery life, and accuracy even when used on sharp recoil impulsive rifles like the SCAR.

What we liked about the Aimpoint Micro is for its ultimate durability for a fixed power 1X optic for close & medium range engagement using its 2 MOA dot.

But there is MORE!

Since this optic is low profile and its favored by tons of people in the community on various combat style rifles, adding a red dot magnifier behind it instantly turns your SCAR into a close-range & medium range rifle. If you choose to…

This tiny and super rugged micro red dot built with 7075 T6 forged aluminum is the gold standard for the micro red dot industry. It’s the best optic for pistols, shotguns, and rifles like the SCAR.

The reason we picked this optic is for its durability and size, which is perfect for anyone looking for an offset red backup sight on their SCAR 17 heavy.

If run and gun is your shooting range routine with the SCAR, then this is it for you.

But here is the best part…

If you plan on mounting a long-range scope like the Leupold Mark 6 3-18X44 on the SCAR, but also want the ability to cant the rifle for close-range shots, then the Trijicon RMR is also the solution.

Trijicon ACOG 3.5X – Best Fixed Power Mid Range Optic

SCAR 17 with ACOG 3.5X best scar acog

Trijicon ACOG 3.5X is the latest ACOG upgrade from its original 4X32 model with significant eye relief improvement.

What we like about the ACOG is its superior durability and its undeniable real world combat proven performance since 1987.

Related Content: ACOG 3.5X vs 4X

Shock-resistant internals proven to hold zero from 22LR to .50BMG and everything in between. So anyone who is afraid of their SCAR breaking their scope should have peace of mind when using this optic.

When mounting the ACOG on SCAR 17 it is best for medium-range engagement with its generous fixed eye relief distance of 2.39″ and an amazing 10mm exit pupil, which is absolutely great under super low light conditions.

Also there are multiple reticles options available. In our testing the simple Chevron reticle for the 308/7.62 is the model you should get.

On top of that, please get an aftermarket SCAR rated ACOG scope mount from Geissele Precision, or LaRue for the tightest mounting solution to ensure absolutely no optic movement shifts during recoil for max accuracy.

  • COMBAT PROVEN: No other magnifed optic has been used more in combat than the ACOG

U.S Optics TS 1-6X FFP – Best SCAR 17 LPVO

If the Aimpoint Micro with a magnifier seems like NOT your cup of tea on the SCAR 17, but you still like to shoot close & mid-range, then the LPVO is the next optic solution you should take a look at.

LPVO has been extremely popular in the rifle shooting world, and it’s a hybrid scope between 1X power and magnified optic. The U.S. Optics has been making custom rifle optics for almost 29 years, and their 1-6X second focal plane is a great scope for anyone shooting close and mid-range targets.

The reticle comes with a 2 MOA center red dot for fast target acquisition with the help of battery-powered illumination. This scope is best for night light use since the 4mm exit pupil diameter isn’t optimal in low light when it’s at 6X.

You probably have heard about the Vortex Razor HD 1-6X a lot because they advertise on a massive level to the civilian market, but when it comes to the real deal check out the U.S. Optics 1-6X.

NightForce ATACR 4-16X50 FFP – Best For SCAR 20S Long Range

Image Referenced Larry Vicker

Why we trust NightForce so much – The NightForce ATACR line of scope produces “bright, virtually perfect image…immune from recoil and just about anything else” according to skilled shooters and our own experiences.

This 7075 T6 hard anodized scope body and its ED glass have distinguished the ATACR as the ultimate precision instrument for long range shooting among military, tactical professional and ranger goers.

The 16X magnification is a perfect magnification level for long-distance shooting without the image being zoomed in too much for easier target tracking.

First focal plane MOA or MIL-C reticles are just right for anyone doing any precision shooting.

On top of that this 50mm objective lens on a 34mm tube body gives the shooter outstanding low light performance & 110 MOA/30Mils of total elevation adjustment, which is plenty for most long range distances up to 500 or 800 yards when using the SCAR 20S’ free float cold forged hammer 20″ 1:12 twist barrel.

Leupold Mark 6 3-18X44 – Lighter & Compact LR Scope For SCAR 17s

Image Referenced IRAQVETERAN8888

Why this might be the best – Following the release of Leupold Mark 5HD, the MARK 6 3.6-18X is a more compact version of the Mark 5HD with just the right amount of magnification ideal for accurate drop-dead accurate shooting. Fits great for SCAR 17 heavy’s overall profile.

Just like anything else, it’s based on SCAR owners’ preferences. When picking between Leupold Mark 6 and the NightForce ATACR, it’s important to understand that they’re very similar in quality.

Both scopes have world-class glass clarity and durability. Elevation and windage adjustments are 0.25 MOA/click also available in the 1/10 MIL dot / click. The side focus parallax adjustment helps shooter adjust focus from any shooting position…

We like the Leupold Mark 6 on the SCAR 17s because it’s only 23.6oz compared to the 33.3 oz NightForce ATACR, which is perfect for non-DMR rifles.

How tough is this American made scope?

All Leupold scopes had to survive over 5000 impacts on the Punisher, Leupold’s recoil testing machine before putting their products on the product shelves.

To put things into perspective, the force of each impact is 3X of a .308 that means the recoil impulse damage we keep hearing about from the SCAR will not affect this optic whatsoever.

Use it with confidence!

Highest Durability Optic Mount Specifically For SCAR

best scar rated optics mounts

The SCAR rifle in the 308 platforms have soft perceived recoil but the gun’s forward recoil impulse when its heavy bolt slams forward after a shot has been fired still poses the possibility for scope damage.

We do our best job to only show you the most durable optics such as Aimpoint, Trijicon, NightForce and Leupold.

The next thing we need is a solid mounting platform that can additionally absorb much of the harmonic recoil waves before transferring that energy to the optic.

So that we can prevent the SCAR 17 from damaging optics.

Here are the ones we trust:

  • Leupold MARK 6 & NightForce ATACR– Sphur Precision Mount, Geissele Super Precision SOPMOD certified mounts [Rated For SCAR], Badger Ordnance 34mm scope rings. CHECK OUT: BEST 34MM SCOPE RINGS
  • Trijicon ACOG – Geissele Precision ACOG Mount with Keeper Nut [Built with 7075 T6 Aluminum provides 2800 lbs of clamping force + 4 recoil lugs for max rigidity & zero repeatability]

Round-Up

Image Referenced Vigilance Elite

The SCAR 17 is a 308 battle rifle and the FN SCAR 20S is it’s a bigger brother for long-range shooting. This gun has its good and bad, but for the most part this is must-have rifle for people who really love guns.

The SCAR 20s is an SSR (Special Support Rifle) kinda like a DMR. The Leupold Mark 6 & NightForce are a great fit for long-range purposes.

Aimpoint Micro & ACOG 3.5X35 are best combat optic for SCAR 17 for run & gun actions, and for home protection an Aimpoint Micro without a magnifier will be the ultimate choice for close-quarter.

Overall you have a lightweight & compact weapon package that puts a smile on your face!
