Dual Rings or Unitized Scope Mount (SWFA 3-15x42mm on AA S510 XS)

I had issues with both the one piece and two piece BKLs when mounted on my .177 HW95. The one piece mounts would slide on the HW95 receiver dovetails even when the horizontal base screws were torqued to 40 in/lbs which is 5 in/lbs above the BKL recommended torque. Also, the scope would shift in the mount rings with 15 in/lbs of top screw torque unless the rings were lined with cloth electrical friction tape........

With the two piece BKLs the scope would slip using 10 in/lbs of top strap screw torque, however the scope tubes were damaged when I used 15 in/lbs of top screw torque on the rather narrow top straps. Notice the distinctive "double dents" ........

My scope mount issues were solved by using a UTG Universal dovetail to Picatinny adapter with Weaver Quad lock scope rings...........

As you can see, the combination of UTG adapter and Weaver high Quad Lock rings sets a scope with a 50mm objective at the perfect height above the receiver tube. The downside is that while there are other Picatinny rings for scopes with 30mm tubes, the nice light weight Weaver Quad locks are only available for 1" scope tubes. The Quad Locks are offered in medium, high & extra high profiles and my scopes with 50mm objectives are to large to use the medium profile mounts.

Anywhoo.......the relatively low cost UTG Universal adapters are one piece functioning similar to the expensive BKLs, however the UTG offerings also includes a scope stop pin which isn't available with the BKLs.

I bought my Quad Lock rings at "WallyMart" for under $10

"Do you think that the slip issues you mentioned would still exist in a PCP?"

Nope, plus the scope doesn't even have to be "springer rated". A couple advantages of the PCP is the fact that a cheap scope will hold up well on an "almost absent recoil gun" which also makes the PCPs easier to shoot accurately. The ease of shooting a PCP accurately and lack of "scope wrecking recoil" does offset the hassles of PCP "care and feeding" such as buying or pumping air, counting shots, dirt in that frammis causing leaks, transporting a "high pressure "bomb" (especially in a hot car), counting shots, so on and so forth.

Back to scope mounts........

My .177 R9 and HW95 springers have a moderate "home tune" (about 13fpe), are twang and vibration free, yet the BKL mounts haven't held on the shallow scope mounting dovetails since the BKLs don't include a stop pin. Perhaps the rather thin wall of the HW95 doesn't allow deeper dovetail grooves so the BKLs don't have a "proper bite". The one piece UTG universal adapter with stop pin did stop all scope shifting, plus using Weaver/Picatinny rings with the mount makes it real easy to "remove and replace" scopes without the need of loosening top strap screws, only the large base clamp screw, on each ring...........

“what does he mean a bomb in the car?”

Obviously uninformed of what 3000+psi air can do if a fitting lets loose inside a car!

"how do you like your Hawke turrets?"

I own these Hawke scopes models with 1" tubes and "front AO focusing"..........

LOL....the Panorama at the top still has the Weaver rings mounted because it was taken from my Beeman R9 springer. I just "twisted the turrets" of all three scopes and the clicks were distinctive and audible. Surprisingly the cheaper Vantage scope had the most "distinctive and audible" clicks. All three of these scopes are of Chinese origin as I'm supposing other Hawke models so perhaps "Chinese QC" comes into play here.

A couple a side notes that probably only applies to my way of scope setup but it works well for me and my recoiling HW springers.......

I first check the "optical centering" of a "new outta tha box" scope by using the easy "mirror method". New scopes are supposed to be optically centered when shipped so if the reticle alignment agrees with it's reflection in the mirror within a click or two I use the mirror method for reticle aligning thereafter. I do this to maintain good scope erector spring tension so the reticle doesn't "wander around" with the recoil of my piston guns. IMHO (or so I've read) that centering the scope reticle also allows light come through the center of all lenses in the erector instead of going through "slightly skewed lenses".

To be able to return to the "mirror optical setting" without returning to the mirror I reset the scale on the turrets so they read zero........

After mounting the optically centered scope I then bend my HW springer barrels till the poi at 30 yards (my usual zero distance) is less than 1" from the aim point. Then I do the "fine adjusting" using the turrets and since I only use "holdover aiming" the turrets are only used for the occasional "fine adjusting". Using this method my turret marks never move more than a "quarter turn" off the "zero mark" when "fine adjusted" (usually no more than 5 clicks with my Hawke scopes). It's easy to know which way to turn a turret to "optical zero" if needed. 

This MAY be of help...........

How I bend my barrels...........

For break barrel "snoop or windage" I've used a "tweaking tree" off the side of my practice lane.........

This "method" doesn't work for adding "snoop" to a barrel so I mage up a "barrel tweaker" that can be used for any direction of bend and the bending can be done upstairs...........

Here is a target I used for bending a new barrel mounted to my HW95 upstairs at 18 yards (fine adjustments were later done at 30 yards on the practice lane using the turrets)...........

LOL....all the above "barrel tweaking" can be eliminated by using adjustable mounts.

Decades ago I tried a couple versions of adjustable mounts and found it so frustrating to have them "shoot loose" with use after spending a couple hours mounting the scope, shooting a group, removing the scope from the rings to adjust the mount, replace the scope in the rings to shoot another group, so on and so forth till the scope "pointed straight. After a few of those sessions I simply started bending my barrels and have been doing so ever since!

Maybe one of these BKL to dovetail adapters with a set of Picatinny rings would work...........

"she's the safety and environmental manager"

Ooooppppssss sorry!

I tried the adapters in the link and they didn't work well with my HW95 since it has a round receiver.
