What is the ideal size objective 50 or 56 that I could comfortably use on a manners eh 1 non adjustable stock. Wanting to try the 4-16 ultra bright 56mm Schmidt Bender but not sure if it’s better to get a adj check or if I can get away with out it? Don’t want to add more weight. If not I think I’ll stick with a 50. This will be a hunting rifle with defiance action and proof sendero.
 
I have a 56mm obj with my EH1 and need a Defensive Edge Kydex cheek rest. Granted it's not much higher, probably .5", but it's higher than the stock for the perfect cheek alignment. I would say 50mm and below. If you want a 56mm, just get the DE Cheek piece. It's very awesome, and very light. WAY lighter than adding the KMW Loggerhead pieces to get the manners adjustable. Pics below show my NF (56mm) on there with my DE cheek riser.

I posed your question to Jerry at S&B and he replied:
"I have 5-20's, a 3-20 ultra short and a 3-12x50 PMII on hunting rifles and have never regretted any of them for that application. The 50mm objectives have never had any issues transmitting ample light during legal shooting time and beyond. I prefer a little more compact set up on a sporter and a 56mm objective usually comes on a bigger scope which I don't prefer for hunting.

Even my 338 edge elk rifle is wearing a 5-20 ultra short with an MSR and I consider that the perfect sporter."

Thanks for the info. That’s really helpful to know!
 
You can run either. I have run both 50mm and 56mm over the years in Manners T3 stocks which have a similar rear end cheek height to the EH1. I always run a stock pack for comfort and don't have a problem getting behind the scopes. Most all my scopes are in 1" height rings but below is a 56mm in a 1.26" height as with my other barrels on this rifle and the Surgeon action the 1" were too low. Still fine with the Triad stock pack and a couple fillers in there.

1" is too low for cycling bolt?scope obj too close to barrel? Or its too low for cheek weld

Too low for the scope objective with scope cpas to hit the heavier contour barrels I have for this action. The integral 20 MOA base on the surgeon sets it lower than it would with a standard base like a Seekins or Badger which i have on my .308 and the 1" height works fin there even with the heavier M24/40 barrels,

I decided to save weight and go with a manners EH-1 non adj. and use a stock pack if i need to.


I would use the stock pack anyway. It makes shooting more comfortable instead of a hard stock in your face it's a padded surface. You can build up under the stock pack as much as you need. You shouldn;t need much but the risers that come with the stock pack should be more than enough.

That's a good point on the risers Rob, I tried installing all the strips and my cheekweld was way above center, so I removed 3 strips and that put me just right with the 24mm rings, obviously YMMV depending on your stock, rings, etc. but like Rob said, play around with the number of strips and you'll find that sweet spot pretty quick.
 
2.5-10 x 42 NXS on EH-1 works pretty damn good.

There is a guy here that can install the adjustable cheek piece for you.... stockdoc or something like that.
 
Yeah, both my S&B PMII 3-20x50 MTC/LT and S&B PMII 5-25x56 DT had the turret bell slightly touch with low .92" Seekins rings. A quick shave of the Picatinny rail in the center and they clear fine.


Guys I’m running into a similar problem too. I’ve got a PMII 5-25 that I am planning on moving to another rifle that does not have a cheek riser so I’m trying to mount the scope as low as possible. I would prefer not to shave my pic rail. By my math, using 0.94” ARC M10’s, I would have have less than half a millimeter of turret bell clearance over the rail. This is too close for comfort because my “math” is based on a guesstimate of the actual measurement of the turret bell-below-the-scope tube body measurement. It’s mounted on another rifle and I just can’t get a good enough measurement to be within half a millimeter precision. I cannot find the actual measurement of this on S&B’s website for this scope.

Does anyone know precisely how far below the scope tube the turret bell extends? Half a millimeter is cutting it pretty close. Going to the next higher M10 ring height of 1.1” is not ideal but I will if I have to at the expense of aesthetics and the possible need for cheek piece installation.

Thanks
 
Don't want to shave the Pic rail? Get two piece Pic rail bases. Viola', done.
No, I don't have the measurement. But, .92" Seekins low rings DO require shaving the Pic rail below the turret bell. I doubt .02" more will clear it. You can do a 1.0 (.08" higher), and that will clear. I doubt you will notice .08" difference in cheek weld.

Thanks, that’s what I needed. My other option was go with the 1.0” Seekins like you mentioned. I’m currently using the 0.82” Seekins for a 30mm scope on this rifle and wanted to try the M10’s. The rifle is a CZ 550 and there’s not a lot of pic rail options out there. I’ll see if I can find pic bases for it as well.

The .82" 30mm lows are way lower than .92" 34mm rings. You can clear a 56mm objective with the 34mm lows and easily up to Proof Sendero or Rem Sendero contours.
 
56mm is nice the sightron's 60mm objective is nicer shame its only a 30mm tube it would be nicer if it was a 40mm tube with a 60mm objective . the difference in how much light it lets in and how bright and clear the picture is is noticeable even with my old eyes even the difference in the glass aside .

I'm using the Seekins 30mm 0.82" rings with an SHV 4-14x50 on a 308. It is just about the perfect height, maybe 5mm of clearance between the M24 barrel and objective bell. It has a nice wooden stock with a fixed monte carlo cheek piece so I am trying to keep it as stock as possible and keep the scope low. But it is now time to upgrade optics.

I am getting a Minox ZP5/MR4 so I plan to swap the PMii that is currently on my 47L chassis rifle (with high rings) over to the 308. That is when I started worrying about that PMii's fat turret bell hitting the piccatiny rail with the lower 34mm rings. The objective should clear the barrel with the 0.92 Seekins or 0.94 M10's, but the turret housing is the issue. I think I will just go 1" Seekins and forget about the M10's.
