Very accurate but scope always has zero wandering issues, not too much but drives me crazy

[SHV]

TR is the best ammo for it
Scoped at 25 meters
Sometimes you can get amazing accuracy sometimes not and sometimes the rings and scope move backwards because the shocks and vibrations
Even put the pin down to the hole on the rail the scope ring screws still keep loose

So I use some parts to DYI peep sight
Cut a 22 case glue (super glue and baking powder magic) to an aluminium ring and cut and trim the ring a little bit, easy job I know it’s ugly but it works

25 meters quick test
Much easier to aim
Much tighter group compares to original open sight which is ok for most of the shots but always a big fly far away from the group each 5 or 10 shot （it maybe is my fault)

Yeah I have same issue with my Gamo rifles of the same model - I have 4 of them. Will get good groups then after about 30 shots its all over the place. Scope wanders around, tried different scopes, mounts but the spring going off rattles them. Resight them in and good for another 30 or so shots.

Not sure if a new spring would be classified as a firearm part or not and if you could import it or not but you can order a tuning kit from airgunheadquarters which will replace the spring, piston seal, top hat and supply the correct lubricants. This will smooth out the action amd reduce recoil substantially. I did this on a gamo hunter 440 years ago and it was a night and day difference. I would also recommend a single piece scope mount on a springer. If available I would also suggest trying JSB pellet of you can find them.

Basic peep sights are easy to make. I've use about 4 or 5mm ones and not a bad compromise for hunting. But to be effective they need to be close to the eye. Not 6 - 8 inches away. See pic.

How about Japanese type 38? Peep in the open sight position, one of the most accurate rifles during the WWII

Maybe at the start of the war they were, mine appears to have belonged to some little bloke who sat in the bushes with a mountain of ammo and just fired the thing into the jungle non-stop for weeks on end
The bore slugs .270" and patterns rather than groups with sideways bullets. I powder-coated some of the Hornady .267" 160gn RN's to bring them up to .270", and paper-patched .243" bullets up to .272", but they're still sideways.

I agree with Oldbloke, apertures near the eye are best. My M96 came with Mojo sight which were replacement front and rear apertures and I don't play well with apertures halfway down the barrel, I prefer open sights over those.

If you got better eye sight open sight maybe better but unfortunately for me the open sight always guess work but the peep sights are more comfortable to use and always much better accuracy

My eyesight is failing me rapidly now, front sights don't exist anymore and rear notches have become "W"-shaped (so I can pick which one I want to look through). But if you practice getting a consistent cheek weld you'll find you can still shoot remarkably well without being able to see the sights.

But the aperture sights work best when it's close to the eye, as close as you can have it without endangering yourself from recoil.

For precision try one of the apertures that fit onto your glasses, like the Eyepal. For about $40 it is well worth trying as the difference is astonishing. I can be looking through my open sights and have no front sight and a blurry W for the rear, pull down my glasses or goggles with the Eyepal on them and immediately have a perfect sight picture. It does not work well at all with aperture sights I've found.

Goggles work much better for me. With glasses, they move with every shot so you have to find the hole in your glasses first, then look for the sights, and then the target. With goggles they stay in place every shot, and when I remove them and put them on again they're still in the same place. Goggles do fog up though so I drilled a hole through them so there's nought but air between my eye and the sights. It means I can't see much through the fogged up left lens though so I may decide to remove the left lens entirely.

I shot with LERAA last weekend, and used these goggles with the open sight SMLE, I don't need the aperture with the PH5 sight on the modified SMLE. LERAA here don't like the Eyepal and consider it a sighting aid, they're happy for me to shoot but I won't be in the running for awards and things, which is fine with me so it's a non-issue. But LERA in the UK do allow the Eyepal and consider it an aid to eyesight rather than an aid to shooting.

[SHV]

you boys are right
I found a piece of plastic from a broken ball pen is perfect size as inset,(tight fits into the 22 case to reduce the hole size) so I can move the peep sight to the back and cut the coke bottle lid as eye piece glue to the back of the sight, remove the open sight then the project finished
And turns out the result is not too bad

The best one’s accuracy is acceptable
If someone has better eye sight may have better results

This is a good idea for the outdoor range at day light, will make the vision much clearer but a little bit darker I reckon…

[bladeracer]

Yep, I find it useless for field use. Normally if I can't find the target I just open my left eye and I'm able to find the target pretty easily in my right eye, or simply shoot both eyes open. The Eyepal seems to disconnect my eyes though so I can't make that same transition (this is not a problem with aperture sights though). On top of that, the lenses do fog up after a little while, except for where I've drilled the hole, so I am pretty much blindfolded while shooting, despite having a perfect sight picture. That's why I'm thinking I might decide to cut out the left lens entirely. It can be disconcerting not being able to see what might be moving into my line of fire while I'm sighting. I want to try spitting in the lens and maybe an anti-fog spray to try to address the fogging.

But it is a means of allowing me to use my open-sight rifles with a degree of proficiency, for shooting steel and paper at least.

My girlfriend and I saw the optometrist on Monday for my annual check-up and he tells us yet again that our eyesight is fine, despite it being obvious to both of us that it is far worse than it has been. I think we need to get a second opinion.

Try a piece of metal sheet with bunch of small holes on it, put on front of eye most of time you will find same thing happen, vision is clearer but darker…. the doctors have those things will let you try to see if vision is better when you do the eye test

[Oldbloke]

Here is a very simple one I made for my ML. There is a slot for the rear screw that facilitates some adjustment L to R. Height is adjusted just bending & with shims.
Peep is 3.5mm and intended use is general shooting and perhaps hunting one day.

P.S. I shoot all my rifles including scopes, ML & 12g with glasses. Not like it was but works fine for me.

Much better position. Same as my ML.

Doctors most often take your age into account when they give you the "news" As in your eyes are fine for a 60 year old. without actually saying the whole specifics.

Not 100% but works.
About 50ml of water in a small spray bottle with 4 or 5 drops of dish washing detergent.
Shake and spray on lens and clean both sides with tissue or soft cloth. Soft toilet paper works fine.

Or

Go to opsm or specsavers and buy a bottle of lens cleaner.

Like case lube, lens cleaner is an exercise in marketing.
