Whenever someone asks how many bucks he/she has to spend to get a good quality riflescope, the first answer that comes to mind is the more you pay, the better you get. This is an age old cliché that is true even currently. On a more general note, if a person really wants to have a great scope, he/she must start looking for one that starts above the price range of US$2,000. There are some established European brands such as Schmidt Bender PMII 5-25×56, Swarovski Z6i 5-30×50 P, and Zeiss VICTORY V8 4.8–35×60 scopes. However, none of them are manufactured in the US. If you want to have a purely US-made high quality riflescope, Leopold Mark 4 6.5-20×50 ERT M5A2 riflescope is surely a viable option for you.

In this blog, we will try to see how good is the Leopold Mark 4 ERT 6.5-20×50 M5A2 Enhanced Sniper riflescope. For raking a closer look, we have selected a purely US-manufactured Leupold Mark 4 6.5-20×50 Extended Range/Tactical rifle scope that comes with 34mm tube, .1 milradian turret adjustment system with auto-locking facility, Horus H58 reticle, wide FOV, and generous eye relief. Leupold Mark 4 ER/T 6.5-20x50mm M5A2 riflescope is a military standard scope that has been manufactured specifically for Remington M2010 rifle system.

Let’s start with the Specs of Leupold Mark 4 ER/T 6.5-20x50mm

Leupold has designed and manufactured this riflescope by keeping military sniper in mind. That’s the reason why this scope has been incorporated with amazing features such as Xtended Twilight Lens System, 2nd Generation Argon/Krypton Waterproofing DiamondCoat 2, generous eyebox, M5 – 0.1 mrad clicks – target knobs, side focus parallax adjustment (75 yards to infinity), 6061-T6 Aircraft Quality Aluminum, Front Focal Plane (FFP), auto-locking elevation adjustment, 1/10 mil windage and elevation adjustments, and many more. This optical device is 14.5 inch long and weighs around 30.9 oz. Other important specifications of Leupold Mark 4 ERT 6-5-20×50 M5A2 Enhanced Sniper Rifle Scope 113780 are 6.5x to 19.5x magnification range, 34mm scope tube size, 14.3 feet to 5.5 feet at 100 yards field of view, 4.4 to 3.6 eye relief, Flip Back Lens Covers, and presence of Horus H58 reticle (located in First Focal Plane). All these advanced specs and features make this scope a highly advanced one and that’s why has become a standard device used with XM 2010 Enhanced Sniper Rifle of US military. Due to the advanced features, this US-made riflescope is compared with the best scopes available in the market currently such as Schmidt Bender PMII 5-25×56 and a handful more. Leupold Mark 4 ER/T 6.5-20x50mm has high level of accuracy and is accurate to the extent of an incredible 4,000 feet.

Testing the Big Boy

While testing the 14.5 inch long and 30.9 oz Leupold Mark 4 ER/T 6.5-20x50mm M5A2 riflescope, it was put over a Savage 111 in .338 Lapua Magnum. We found, during testing, that this riflescope works extremely well during extremely low light conditions – dawn as well as dusk. This has become possible due to the incorporation of Xtended Twilight Lens System. If this feature is compared with the Index Matched Lens System of Leupold, this feature is found to be of superior quality and produces a better output. Leupold Mark 4 ER/T 6.5-20x50mm M5A2 worked extremely well when just a few minutes were left before dark.

We noticed that Leupold has ensured that the lens comes with highest abrasion protection level, ensured by DiamondCoat 2, which is an ion-assisted lens coating. This system is even better than the earlier system Leupold used in their premium scopes. The 34mm M4 tubes of this riflescope is now filled with Argon/Krypton in place of nitrogen. Therefore, now the Leupold Mark 4 ER/T 6.5-20x50mm M5A2 riflescope is more effective in terms of waterproofing as well as reducing thermal shock.

One of the best aspects is surely the decently sized eyebox. With this scope in hand you can acquire target quickly. The FOV at highest magnification is just over 5 feet and the same is over 15 feet the lowest magnification from 100 yards. Only one aspect that made us a bit uneasy is the heavy weight of the scope. This rugged big scope weighs above 30 oz but most long range hunters as well as tactical shooters are quite alright with this weight of the scope.

This scope will be especially useful for those who are instinctive shooters and the main reason being the magnification of the reticle in accordance with the image viewed through the scope. Therefore, range estimation can be done rapidly throughout the entire magnification range. This is the reason why both tactical and hunting shooters love targeting moving targets through this scope.
Leopold Mark 4 6.5-20×50 ERT M5A2 riflescope is purely a medium to long range scope. If your average range of shooting is 75 yards, this scope will surely be a liability to you. In case, you are mulling the idea of buying this riflescope, it needs special mention that you should go for it only when you are aiming targets at longer distances.

After using this scope with the Savage 111 in .338 Lapua Magnum, we put it on a long bull barreled Colt HBAR Elite. It was then sighted at 100 yards and the entire process was lucid, taking only minutes to get it done. While checking out the image clarity through the scope, we didn’t find any issue up to 500 yards. As always the case, long range shooting is a playground for the pro shooters and not so much for the amateurs. If you want to get a perfect shot through this Leupold Mark 4 6.5-20×50 Extended Range/Tactical rifle scope you must have a steady hand, have enough control on your breadth, easy transition ability from unaided FOV, and good standing capability of shooting.

Conclusion

Leupold Mark 4 ERT 6-5-20×50 M5A2 Enhanced sniper rifle scope is a military standard riflescope whose listing price is way above the US$3,500 threshold but is available at way below US$3,000 price at some renowned registered dealer of Leupold. If you are a pro shooter and place quality of shooting and preciseness of target acquisition above any other factor, this riflescope is the right choice.
