Standard Two-Piece Scope Base

I purchased these bases for a Browning A-bolt Medallion in 243 WSSM. NOTE: These are specific fit bases for this rifle. If you have an A-bolt that is not a Winchester Super Short Magnum, these bases are not for you. The fit and installation of these bases was simple and very high quality. I matched them up with some engraved Millett Rings and it really complemented the appearance of my Medallion rifle. They are sturdy and rugged enough for any caliber rifle.

I love the Leupold STD bases and rings. They look great, do not loosen, and are easy to mount with the correct scope mounting tools. Koodo's to Kimber for the 8-40 threads in the receiver. The provided torx wrench works great.

Ultra fast service, new in box as advertised, no issues

Leupold is quality

I bought windage adjustable bases to adjust for some seriously misaligned scope mounting holes on the receiver of an older Model 70. I paired the bases with Burris Signature rings so I could use the inserts instead of messing about lapping rings. Worked great for that and I was able to adjust ~24" of windage and get zeroed with minimal scope clicks. However, I have a few other probably 15-25 year old sets of Leupold mounts for other rifles and those clearly have better worksmanship/finishing. These newer ones have a noticeably rougher finish and sharper edges. I have no reason to believe the new ones won't hold up - just disappointed in another shortcut to save an extra buck.

I favor the Leupold/Redfield style of mount because they allow solid ring mounting without a lot of fuss. The mechanical dovetail front is easy to install (no scope tool? Use a dowel or a piece of 1-inch PVC pipe). The screws provided are high quality Torx head screws, and they have a bit of blue loctite already on the threads; I found this a nice touch and highly convenient. The rear mount has a modest amount of windage built into the ring mounting screws. I purchased my set for a new Browning X-Bolt. The Leupold set fit the provided mounting holes perfectly and installed without any surprises. I also like the fact that Leupold provides the proper Torx wrench in the package, so you don’t have to hunt for your toolbox or Allen key set for installation. For endorsement, no rifle I own with the Leupold/Redfield Austen has ever had any problems with accuracy or shifting zero. While I have other bases such as Weaver, Millett, Remington, and Tikka, I much prefer the Leupold system, even though I am not a Leupold scope snob.

Bought these for a Centurion model 30-06 that was described to me by a BassPro gunsmith as being a Mauser style. Must have tried a least a dozen different mounts at BassPro/Cabelas and they just didn't have the right one for this gun. I was very pleasantly surprised that this was a perfect fit and it allows plenty of room for the bolt action and ejection of cartridges/shells. Mounted a 3×9×40mm scope on it, has a semi raised profile that would probably work up to 50mm and the mounts have held up and scope has held zero with close to 50 rounds fired through it so far. Make sure to use a little bit of Loc-Tite on the screws when assembling, or just take it to any decent gunsmith for install.

The rear base in the picture should be turned around. If you mount it that way; the bolt won't open. I bought this to replace a one piece base that I had on a Remington 700 in .30-06. With those mounts, the rear ring sets farther forward. I also bought an extended ring for the front. Long actions seem to put the scope too far forward in my opinion. The Objective end of my scope's outside diameter is 115/16 inch in diameter. I bought High Rings. The bottom of the scope in the front clears the rear of the rear ramp sight enough that the ramp doesn't show up as a blur when looking through the scope. I recommend putting gun oil on the front mount and then using an open end wrench to loosen up the ring in the base. A few turns back and forth makes a big difference. This design allows you to get the scope lined up with the barrel as needed. I have a Winchester Model 70 that I installed the Dual Dovetail Bases on. I couldn't get the windage in the scope to line up right. I used a Bore Sighter. Somebody at the factory messed up.

arrived on time & just as described :)

nice

as expected for the name - great quality

What can I say LEUPOLD! FYI: these fit Savage 93R17 too, that's where mine are
