This scope, I put on my 22-250 and it's perfect for coyote and bobcat hunting. It has a clear glass and functions well. I've had no issues with it.

Mark 3 HD 4-12×40 mil

I purchased my Mark3 HD 4-12×40 through Euro Optic. For the $600, it's a decent scope. I like the TMR-mil reticle, especially for shooting out a little further. I've had no issues getting 1st round impacts out to about 700yds (with proper info and ballistic calculator). The only complaint is you only get about 1 rotation of elevation, so I would run out of dial and move to holding over using the reticle. Still a good, clear scope.

Great scope perfect on Remington

Great scope perfect on Remington 700 308 with 20 in barrel. Dead on, every time, when mounted on mark 4 mounts. Clear glass and firedot makes target acquisition quick. The TMR takes the guess work out of elevation adjustments on the fly.

This is the perfect blend

This is the perfect blend of quality and a smart budget. You get all the quality without breaking the bank. Firedot is a must for early morning or last light hunts.

Originally I planned for this

Originally I planned for this scope to be used on my Ruger Mini 14, it has since found a home on my Ruger American . 308 Win. It is a great compact scope, the 1. 5-4× magnification is ideal for woods and field deer hunting, and I really like the FireDot for fast woods sighting especially in low light conditions. Added Bonus- the BDC reticle, when sighted in @ 200 yards, gives me 300-500 yard capability if the occasion calls for it.

Optic is great and love

Optic is great and love the red dot aspect as it's very easy for your eye to lock on too. Almost took a star away due to not finding any info and had to contact customer support. (They where fast and friendly. ) Mounted to a 6. 5 creedmoor ruger american ranch 16 inch barrel and shot to high maxing out the turret. Just had to remove turret and adjust with a wrench than install turret at zero. Everything is good to go now.

Mini 14 Marriage Made in Heaven

Got this scope for a Tactical scope for my Mini 14. The 'meat and potatoes' of this rifle and scope is 0-200 yards, and the BDC works out in my rifle with Frontier #FR260 with 62 gr FMJ as 310, 360, 408, 455, and 501 yards. Sure hits on 100% size IPSC silhouette steel. Love the red dot reticle for fast fast fast target acquisition, especially in low light when crosshairs can get lost in deep shadows. At 9. 5" and 13. 1 oz. complements my Mini perfectly so it stays fast handling and light weight.

Variable scopes may well be

Variable scopes may well be popular and sell well but I am a fan of fixed power for specialized purposes. Too bad you cut back on fixed power production so I am forced to crank in a setting and keep it there. Anyhow, you continue to make fine products and I like my Leupold scope.

Greta for a BB gun scope

The red dot at the three highest setting is when it's possible to see even in a dark room at night, the hold overs are very hard to see also even when looking at the target, i own three other luepolds and they are all of high quality don't know where the quality went on this one if they won't let me return it I will put it on my grandson's Daisy Red Ryder very disappointed to say the least

Ticked all my boxes

My Mark 3HD 4-12x40 Firedot TMR ticked all my boxes for a shorter barrel . 308 bolt gun. MPVO. Very usefully illuminated. Very light weight. Mil-Dot second focal plain. MRAD turrets. Elevation good to 600m, with stop. Good glass. Good warranty and real support. Lacking a fifth star because they included the wrong size Allen for the elevation turret. Should be 1/16", not 0. 05". Also there is play in the windage before first click. And I could only get it at MSRP, which was expensive after adding their nice caps and good rings.
