I recently bought a really nice Gamo hunter sport air rifle. it came with a very nice 3-9x40 scope made by BSA.

the rifle suffers from one major problem... the scope shoots to low.

ive raised the scope as high as it will let me adjust it, but it still shoots about 3 inches too low. its really irritating to have to aim 3 inches above the target and hope that i hit it.

i know i could move closer, but im only shooting at about 100 feet so i think it should be able to handle it.

does anyone here know of a solution?

shim the scopebase, the rear i believe. gunsmiths do it. or try another set of bases. your bsa might be bad also

As suggested above you have to shim the scope, the favourite material is a bit of photographic film.

If you're shooting below the crosshair, put a shim between the scope and the rear mount. If your shots are high, put the shim between the scope and the front mount. Start with one and add as necessary. Remember, NEVER overtighten scope mounts, as scope tubes are very easily crushed and that will screw up your scope permanently.

So you have a gamo and you're shooting it at 100 feet?

Good luck, trooper.



But for serious, you actually zero it at the minimum distance you are going to shoot + the maximum distance you're going to shoot / 2.
And then you can count the mil-dots.

Seeing as it's a gamo, the pellets would just hit the ground at a meter or 120...

I've seen people hit 1" targets reliably with Gamos at 30 metres, it's not that impossible if you're a good shot.

I have a Gamo spring air. I constantly shoot it at around 100ft and it has never given me any problems (but it's been chronoed at around 1200fps also so...)

OH, right, i was turning around yard and feet again......

hehe in that case, shooting a Gamo at 100 metres, you'll be lucky if you can hit an A3 sheet of paper

Gamos are very good air guns. mine shoots in the exact same spot every time, it just shoots low. its also very well built. i see what you guys are saying, im not going to take it to a gun smith, but i did stick paper clip under the rear mount. i'll have to see if it does anything. i did notice it raised it a little.

if all else fails i'll put the scope of some other gun and buy a red dot sight for it...

thanks for the help, any other suggestions are welcome.

Maybe your rings are messed up? I used Simmons rings on my Tasco scope. They aren't very expensive, just like $7 at Walmart.

BSA scopes stink, from my experience. I had an adjustable one on a pellet rifle, and it wouldn't ever stay consistant. I put a Tasco on, and now I'm shooting pennies at about 30-40 feet.

A paper clip is far too much of an adjustment, you need thin sheets of plastic as shims so you can do it in small increments, which is why I suggested photographic film.

burris makes rings that use inserts with the option of offset inserts ..
they help in a couple of ways .
they claim no scope dings or crushing of the scope like jack mentioned.
they also let you center the scope adjustments and use the offset inserts to dial in windage or elevation problems without using up internal adjustmants..
a bunch of benefits in that.
they make a air gun dovetailed model.
I haven't used the airgun setup only the burris for weaver/pitcanty on .270 and 30-06.
no complaints

the quick way to center scope adjustmants is to put the scope up to a mirror you'l see your retical and a ghost image of it .
use your w+e adjustments to align them.
traditional method is to cut 2 v notches in a shoe box rotate and adjust scope in these notches until crosshairs stay in the same spot when you rotate the scope.
you should get the same results either way.

you have a decent gun and more important you both like it and can shoot it .
thats all that matters.


for what it's worth

A paper clip is far too much of an adjustment

i finally got around to testing it. you might be surprised if i said that the paper clip was actually almost perfect. it works perfectly now. (i told you it was way off)

thanks for the advise.
