I remember these little black padding strips came either with the scope, or with the mount. I put them in and now one has drifted out. Is it necessary to have this? If so, what do I replace it with? Or can I just clamp it down metal to metal?
I actually have a set and no complaints. Had a picture in my head of silver scope mounts to go along with the silver parts on the butt pad and cheek riser of the Craftsman Vit stock I had coming for my HW95.I suggest BKL mounts. They have an excellent line up of products and are made in The Great state of Texas.
I for one cannot give a definitive answer. I have a Diana 54 Air King Pro, recoilless and it is alleged one of the guns to be super destructive of scopes. The need for a tight fit both to the scope and the rings to the gun may have to do with the recoil impulse, impulses being contained within the air gun cylinder barrel assembly and attached scope, On my other recoilless rifle, a FWB 300 that is what I can see occuring, although I only have ever had the factory diopters mounted on it.I imagine the radius of the hole is wrong without the tape. Does it match the scope tube now? If it doesn't at very least you're gonna get some ring marks. Might affect your ability to zoom as well. I personally don't seem to have any problems with various brands as some seem to. Only Sportsmatch I have are on my Daystate which is recoiless and in this case they are really overkill. I never needed bank vault rings for my .22RF's so why would I need them on a recoiless? The scope tube slipping has never even been an issue on any of my many springers. Have to say BKL are nice because they mount your scope squarely over the barrel. Side clamp mounts don't ever quite accomplish that. I have single strap BKL on my magnum Tomahawk (22 ftlb) and the scope tube has not slipped yet after several shooting sessions. I tried them because I had them here on hand
If the shoe doesn't fit don't wear it.
Ron, You maybe, and probably are, right about the 56 in lbs, but why on earth would anyone need to torque the rail screws that tight?People like what they have. If it works for them God bless.
I will tell you the Sportsmatch are a better design and better made than BKLs. Primarily because the BKLs have been known to slip because there's no recoil pin.
The part about the BKLs tighting evenly is a non issue. All rings tighten evenly. This is different than being centered. For that the BKLs are much better than the cheap Chinese Hawke or UTG. The Sportsmatch are made specifically for 11mm airgun dovetails so they are centered within a few thousandths of an inch when tightened.
The Sportsmatch rings don't need any bogus tape to make up for sloppy tolerances. They are also made with better materials and fasteners. The dovetail clamps will hold the recommended 53 in lbs with no problem. The Hawkes and UTGs will strip long before that.
The Sportsmatch rings and caps fit the round scope tube perfectly. They secure my heavy Airmax scopes on my 20 fpe R1 with only 16 in lbs of torque.
I know I sound like a broken record about this. In fact there's people here that mock me about it. Frankly I don't care. This is mechanical tangible facts not bias.
Use what you like.
I wrote 53 and 16 in lbs because that's what I've been using. I just double checked and I was wrong. Sportsmatch recommends 55 in lbs on rings with 5mm dovetail clamp screws and 38 in lbs on mounts with 4mm dovetail clamp screws. They recommend 15 in lbs for the caps. Not 16 as I suggested. Their Weaver clamps are tightened to 28.Ron, You maybe, and probably are, right about the 56 in lbs, but why on earth would anyone need to torque the rail screws that tight?
BKL Mounts are self aligning. No need to lap rings anymore.No one laps their scope rings anymore?
Granted, manufacturing tolerances have greatly improved over the years, but lapping the rings can only improve the accuracy of a given rifle scope.
I see that BKL rings and mounts are manufactured from aluminum; their “self-alignment“ feature is accomplished by relief cuts and flexing.BKL Mounts are self aligning. No need to lap rings anymore.
