AR Scope Mount vs Scope Rings

[FUBAR]

I just purchased a Ruger Precision Rifle in 308 and deciding on how to mount a scope. Should I go the two extra high sope rings or one of those AR scope mounts like the Burris PEPR?

Kinda depends on what kind of scope. Some scopes require a long eye relief, so you use the AR-style scope mounts to push the scope forward. This allows it to only be mounted on the upper receiver and not be on both the upper and the rail. With scope rings you may need to mount one set of rings on the upper, and one on the top of your rail. I opted to mount mine with the cantilevered AR mounts

If I go with the cantilever scope mount, should I go with the extended version?

Which two mounts are you looking at? also which scope?

I have a 1-6 on mine and use a 2" cantilever mount

I have the Burris PEPR QD mount on a AR, I also have American Defense mounts on another AR. The American Defense is by far higher quality, and like another forum said, Spurh mounts are excellent. I'm not really sure what a advantages a mount would give you over rings, I prefer rings only on bolt guns. On gas guns, QD mounts only. It's personnel preference obviously, you just have to look at what your going to use it for in the end. Are you only using high rings due to your objective lense?

whoops. I didn't see you were using an RPR. You may not need to cantilever your scope.

one way to find out is to get your scope and a couple decks of cards. stack them up and find the eye relief you need. see if there is a place for your tube to mount rings directly to your receiver. haven't shot an RPR so take that for what it's worth. That's just what I would do

Normally I would say get rings on a bolt gun, but depending on the size of your scope the AR style mount might be a better choice to get clearance over the handguard while still maintaining your ability to take it off for cleaning or upgrading.

With that in mind I would look at the Bobro (SWFA has an exclusive model) or a Larue. Both are going to be pricey but quality. Spuhr mounts are always a good choice but come at a premium. American Defense mounts are also solid but I have seen their screws break on my buddy's AR which gives me pause. Not that the hardware reflects the entire product but if you are paying a premium, quality components should be a given. If you want to go with standard rings I have been very happy with Seekins Precision.

I prefer 1 piece mounts but a 2 piece will be fine.

I don't bother with QD - some of the popular lever mounts on the market are not that good and I've been saying that for a while. Clamp mounts are superior in terms of strength and clamping force.

Depends on your scope. You need to tell us what scope you're using.

Also, don't get a QD mount. There really is no need for one on a bolt gun. Rings should work just fine on the RPR: https://www.google.com/search?q=ruge...w=1920&bih=987

Seekins offers rings in different heights to accommodate different scopes and flat top rifles. But before you go buying rings, you Need. To. Tell. Us. What. Scope. You're. Using.

Ok. So...

The objective bell diameter for the SWFA is listed at 49.5mm / 1.949". Rings are typically measured from rail to the center of the scope tube. So for this scope you will need rings that are at least 24.75mm high. Add some additional clearance if you plan on using scope caps.

For the Primary Arms, its objective bell diameter is listed as 50.8mm. Half that is 25.4mm. So you need rings that are at least that high. Again, add more for scope caps if you plan to use them.

Seekins offers good rings in various heights that will work for you. The eye relief on your potential scopes doesn't look to be more than 4 inches. So you should be fine with rings on the RPR unless you plant your peepers super close to the receiver. Remember, this a bolt action, not an AR15. Don't shoot nose-to-charging-handle On the flip side of the coin, if you plan on shooting out to long-range and want some cant to your scope so you can have more elevation adjustment, you might want to look into a canted single-piece mount (20 MOA). For your .308... depending on the scope's internal elevation travel, you might need a canted mount to reach 1,000+ yards. I would avoid quick-detach mounts.

Thanks FourT6and2.

Solid advice right there
