Rifle Scopes S&B Sunshades

[DeltaDan]

Looking to get a sunshade for my S&B scope. Both the aluminum and rubber one are the same price. Any advantages of either? Also saw there is a killflash available, in my experiences these seem to kill light transmission a lot to, is this still the case with excellent glass and a 56mm objective?

USO has them as well. Their ARD is pretty good as well.

What model S & B do you have? If you want accurate info that relates to your specific application you should be specific about the equipment that you're using. Also, speaking from personal experience, a better ARD (anti-reflective device) will not noticibly affect the image quality of high-end optics. IMHO, the honeycomb insert that USO uses in their ARDs' is the best - it is very efficient in reducing off-axis light (which helps eliminate image "wash-out") in very bright/intense direct light. The USO ARDs' do this without compromising light transmission.

I've used 4" and 2" USO ARDs' on USO SN-3s' and 2" USO ARDs' on a Premier Heritage 5-25X56mm and S & B PMII 5-25X56mm scopes and the results were universally excellent. I use a 2" USO ARD to help keep dust, grit and the elements off of the objective lens. It works pretty well for keeping rain out unless the wind is driving it hard.

I highly recommend the USO-manufactured ARDs' and Sunshades made to fit the 50mm and 56mm PMII - I <span style="font-style: italic">think</span> that USO made a 42mm at some point as well. The USO ARD's honeycomb design is very efficient and the housing is quite robust. I've used USO ARDs' on several scopes including two PMII 5-25X56mm (2"), a Premier Heritage 5-25X56mm (2"), a USO SN-3 3.2-17X 44mm ERGO (4" and 2"), and a SN-3 3.2-17X 44mm TPAL (2"). From what I've seen, the build-quality and performance the honeycomb-design in the USO ARD unit is better than the Tenabraex ARDs'. I haven't used the S & B units.

Although I only shoot on a one-way range, my USO ARDs' serve two purposes for me:

(1) Help keep dirt, rain, and other crap off of the Objective Lens. This minimizes the chance of having to clean the lens, which reduces the necessity of lens cleaning, which reduces the chance of scratching an (expensive) lens.

(2) The ARD actually helps sharpen the target image because off-axis light is prevented from entering the scope (off-axis light reduces image quality). This effect is noticible whether I am shooting from a covered firing line or in full sun.

I've found the USO ARD is so efficient that I just leave it on. On the rare occasions that I have used the scope at night the ARD did not reduce the image clarity, requiring removal, although your eyes and the particular scope in use play a part as well.

Not only are the USO ARDs' very efficient - they are also very well made. The USO ARDs' consist of three (3) components:

(1) A threaded, Type III hard anodized aluminum housing, (which by itself is the USO Sunshade), (2) a high-efficiency anti-reflective <span style="font-style: italic">"honeycomb"</span> insert that is expoxied into the aluminum housing, and (3) an aluminum "Stop ring" that limits the depth of the honeycomb insert within the housing.

The <span style="font-style: italic">actual</span>, OALs' of the Housings are .25" longer than the <span style="font-style: italic">installed length</span> (male .25" threads into scope). Therefore, the OAL of a Sunshade (or an ARD) of a 2" USO Sunshade or ARD is actually 2.25".

Re: S&B Sunshades

Thanks for the informative post! Exactly what I'm looking for my PMII 5-25X56mm. Where is the best place to acquire one these USO ARDs?

Re: S&B Sunshades

Thanks Aries 64 for posting all the pics and information! I think I'll ring up the good folks at USO and see about an ARD/sunshade for my S&B 5-25x based on your information.

BTW, that's a mighty spiffy scope you have on that 10/22

Thanks for the compliments guys. As far as <span style="font-style: italic">"the best"</span> place to buy the ARDs' goes - I would call USO first. USO only makes a run of them when they are ordered in minimum quantity, so if they're out of inventory they may suggest other Hide' vendors who also carry/have carried them in the past.

Thanks. I actually sold that Premier 5-25X and it's ARD and used the proceeds to help fund the purchase of my second PMII 5-25X 0.1 MIL Gen 2 XR. After having the turrets converted to CCW that scope found it's way on top of my Kimber Model 82B Classic in .22LR. Below are some photos of said PMII in NEAR Manufacturing 34mm LOW Rings.
