Rings loosen after firing
590326
Rings seem to come loose after some use which can cause issues with the scope no longer being properly sighted.

These snap caps work just fine in my Glock 19, but they have issues in the Glock 43. Once the trigger has been pulled and released, the slide is locked into place and you cant manually cycle it. It seems it has to do with the firing pin getting hung up and not resetting properly. In order to eject the round, you have to either keep the trigger fully depressed while racking the slide, or field strip and remove it manually. I bought these primary for my wife to practice clearing malfunctions in her gun (G43), but Ill have to find a different brand that works for that model. Ill keep them for use in my other pistols, and they were inexpensive, so Im not too mad about it.

Mounted these rings on my sons competition rifle and so far so good. They have noy come loose so far' but he has only shot 2- matches with them on his rifle. Will let you know how they hold up.

Thumb nuts rust.  They fall off when loosened too far because threads are not staked.
On Magpul rail sections, after seemingly fully tightening thumb nuts, HS-802 flashlights are not always clamped tight.

When you cycle these through your gun the soft aluminum gets eaten by the extractor. This will lead to small metal flakes in the gun, metal clumping on the extractor, and rounds which will not eject due to missing metal on the rim.  These will work for you but not for long.  I used them for dry fire training and these last less than 2 months.  I have since switched to snap caps which have a brass base and have lasted over a year and still work great.

I was setting up my 10-22 for a CMP rimfire event. The scope I have on the gun is short, more for a AR style gun.  The problem was with that scope on my gun the eye relief was too far forward.  I saw these and thought they may solve my problem.  When the rings came in I was struck by the simplicity of the design.  Instead of clamps on one side of the ring which could put the scope on one side or the other of the center line of the receiver depending of the width of your scope rail.  This slide onto the scope rail, you put the screw through the ring assembly and tighten it up and the ring pulls in from both sides evenly and clamps the ring into place dead center of the scope rail.  These things are rock solid.
The interesting thing was before putting these rings on my gun, it seemed to shoot an oval pattern which was more noticeable using HV ammo.  Evidently the original rings had a bit of slop allowing the scope to move with each shot.  So these gave me better eye relief and a tighter pattern.  Whats not to love.

Rings are heavy duty. Mounted a scope on a Savage 220 slug gun with these rings. Have no issues yet and don't expect any.

I did not care for these rings - I temporarily installed and the screws self tighten... so tight, I could not remove them. After breaking the tool it came with, had to drill them off and ruin the rings. The rings were fine until this happened.

The swivels fit well and seemed like a perfect mechanism for my rifle.  However hiking thru thicket deer hunting to my stand the lower swivel loosened on the second day.  not sure if I had screwed the attachment screw completely when I adjusted the length of my strap.  I rescrewed the keeper.  Two days later the again hiking thru a thicket to my stand the lower swivel again loosened and separated from my rifle. Since I was wearing a heavy coat and a pack I didn't notice my rifle had fallen until I got to my stand.  I had to wait till daylight to retrace my steps not sure if I would be able exactly retrace my steps accurately enough to retrieve my rifle. in the thicket/marsh I had walked thru.  I can't trust theses swivels.  I will be replacing them.

Got loose a little after multiple openings, had to tighten twice now..using grip oil on screws so they do not move now.

Either the clamps were not machined properly, or they were not not designed properly.  When tightened down on the base, the part that I'll call the mobile side of the clamp did not seat very well into the groove in the lower half of the ring.  I could tell visually that the stationary side of the clamp was slightly lower than the mobile side of the clamp. I hope this makes sense.  This added to the frustration I had with the genuine Weaver bases I had purchased that were not drilled properly to allow the screws to sit flush in the front base. This was far from my first scope mounting, but it was the first time I've had problems with either the base or rings.

solid stainless steel rings.  it was expensive AF but they are the best rings you can buy.

I wish I would have bought some medium height ones too for long range shots.

I bought these for my 1969 winchester M70 in .338 win mag.  I have a Nikon prostaff 4-12x40 BDC scope siting in those rings, torqued and threadlocked. The rings have held up to 16 shots on my .338 and are still going strong. I put them on a picatinny rail and I found out you have to slide them onto a picatinny rail. These are by far some of the best rings I've ever used.

Not only does it feel loose on my firearm, but after firing a few rounds the laser moved all over the place.
That's not very reliable, had to return.
No recommendation.

Mine came super loose, gun (Springfield mod. 2) would just fall out. Found a guy locally who said he could put a tensioning screw might have to do that.

i like the light stoppage, but not so much the ring. i would prefer a brass ring like some of the higher end brands, but i rarely need to shoot with this much stoppage, so this price point was decent for me. The threads screw in well, but like i said, it' not brass, it feel like it would break/bend if mishandled.

I use my case for my reload block and find that it is a little too deep and the shells fall out of the reload block if it doesn't remain flat.  Started shimming it to provide a tighter fit.
