Use a flat feature on the scope and reference it to a flat feature on the rifle.
Scope bases usually have a flat top.
Most scopes have a flat under the scope 180 degrees from the elevation turret.
Lacking that, use the top of the elevation turret.

Old trick... use a deck of cards between the rail and the scope.

Rifle goes in a vise, rifle gets leveled on the scope base. Scope goes on and is leveled using a Arisaka Defense scope leveling tool. Bubble level goes on scope and is checked against the level on the scope rail.

i am just curious as to how you do it. My method is to slide a hex wrench that is closest fit between flat bottom of scope and top of rail. If there is a little bit of a gap twist the hex key until it touches evenly on both scope and rail and shine a flashlight to see if there is a gap where light can pass through. If there is no gap then i know it is set.

but i like the deck of cards idea too

Feeler gauges used for car cam shaft/valve clearance. Best method, IMO.

You can use a smaller size parallel too but honestly, the Arisaka Defense leveling tool is very inexpensive and works much better.

I'm looking for my first bolt action rifle and want it in .308, is the RPR a solid choice for a first time bolt action buyer?

IMO no, but I like wood and pedigree. RPR has neither.

On the other hand, if you don;t care about either wood or pedigree, why not? A rifle is a rifle in that case, right?

I was reading an article about leveling and they found the human eye can easily detect square/vertical/horizontal within a half degree. Most can tell within a quarter degree or less.

The article pointed out all the problems with mechanical levelers. Your vise may not be level. Your stock/barrel interface might not be level. Your rail may not be level, your scope base or caps may not be level. Your level may not be level.

I've also mounted scopes with tolerance stacking problems with all of the above. The errors compound themselves to become very obvious errors. Everything checked out perfectly, yet when you got behind the scope it was VERY obvious the reticle was canted against the gun.

My whole life I've basically used the eye test as my final check no matter what the technique I've used and it's saved my butt more than once.

I've never found a foolproof method that was better than just my eye.

So after reading the article, I decided on my RPR to try the eye test only. I mounted it all up and took it to a 4 day long range class and it performed flawlessly out to 1,200 yards (we didn't shoot further than that).

Interestingly, my OCD friend who jumped through all sorts of hoops to level his scope using a bunch of fancy equipment and techniques was struggling the first couple days of the class. So in the hotel room that night, I did the eye test and his reticle was off. So we corrected it simply using the eye test and he shot lights out the last 2 days of the class.

I think the level may help me to be consistent if anything else.
It's certainly easy to glance at briefly.

If you need a way to measure scope cant, tall target test. Pretty straight forward.

Regardless if you install via shims, eyeball, black magic, plumbbob, paid gunsmith, whatever.

What's your intended use? Hunting? Then no. It's not the best for hunting due to its weight. Getting into Precision long range shooting? Then yes, it's a very capable rifle out of the box and well worth the asking price. And I'd recommend the 6.5 Creedmoor. It owns the 308 as far as ballistics are concerned.

I'd really love to take my RPR in 6CM varmint hunting.

Would the twist rate to be too fast for light varmint rounds like the 58 or 65 gr Vmax?

Here is the new bolt shroud on the right. You can see it's milled very differently, in the documentation they say it will fit loose and it does wiggle around a bit after installing unlike the original which was a tight fit. The flip side is it's much easier to seat it in place now. Getting the little tool to unscrew on the back was a pain, I had to use pliers and protect it with some tape to prevent marring. Once it was off a little oil made it hand removable.

Just got my replacement shroud today too, so just under 4-week turnaround time. A couple more pics, because pictures are fun:

Pretty simple to level your glass. Level your base, attach glass, attach level. Adjust. Level never lies.

The level lies all the time. Just rotate it 10 degrees on the scope tube!

What doesn't lie is the tall target test.

In my experience, installing a scope level that attaches to the scope tube, if I align the reticle to a plumb bob placed off a ways, and ensure the bubble is level, I'm GTG. Regardless of how I have it on the rifle.

But I don't really shoot many tall target tests.

Thanks for the info again. finally cut mine down today. It was a bit nerve wrecking but I got it done. Did not have to shorten the buffer tube but did not trim it quiet as much as you did. Balance already feels better just trying it in the garage.

Glad it worked out for you! Post a pic!

I think 6.5CM brake should be fine? I asked the same question in another thread...except for a 6.5CM. most of the brakes, when i was shopping for one are made for .308/30cal. did a little digging and most folks were able to use the .308 with 6.5CM

I would think the 6.5CM should be fine.

Get the 22 caliber model and open it up to 0.020" over bullet diameter.
