Crosman's Optimus air rifle delivers authoritative knockdown power. This version comes with a CenterPoint 4x32 scope + mount. Take common garden pests such as rats, mice & rabbits. The scope will help you home in on your prey and increase accuracy. If you want to take slightly larger pests (possums, woodchucks, raccoons, etc.), select .22 caliber.

If you prefer to plink, this gun is up to it. Shoot at spinners and paper targets all day long. It's also great for killing soda cans!

Things I liked:

Surprisingly accurate and powerful for a break-barrel air rifle.

Things I would have changed:

Considering the price .. nothing

What others should know:

I did perform a simple trigger modification using a ball bearing. Well described on YouTube.

Things I liked:

As I wanted spring, and not gas, piston. Durable. "Accurate" once the sights are sorted out Weight.

Things I would have changed:

Much better "iron sights". The fiber optic sights that are installed are wayyy off on proper mounting. Almost past the point of correction. Hence 4-stars. Don't waste money on a scope. Longer barrel. Sling mounts.

What others should know:

Rifle has good weight. But not light. Cocking force is usual for this power, but some may find it difficult. I have a similar rifle in .177 that is about 30-years old and still works well. Hopefully this one will be the same.

Verified Purchase

Things I liked:

I wanted a springer twin to my recently purchased Vantage nitro that I fell in love with. And I got it. Simple, streamlined looks and excellent shootability with power and accuracy. At a heckuva good price.

Things I would have changed:

I shoot open sights and cannot see why Crosman doesn't just improve these and forget packaging the cheap scopes. Use real sights that don't look like they came from my granddaughter's Lite Brite set. They aren't even compatible with a peep

What others should know:

I put 400 rounds thru this gun before it even saw paper. Just keeps getting better. And like the Vantage, it likes heavy pellets, and so do I for taking game. I was prepared to give it a tune in a tube, but it shooting so smooth it simply does not need it

  • Andrew from USA asked:

    do the rear sights get in the way of the scopes optics?

    • goosedowner from USA asked:

      Where is this gun made?

      • Mark from USA answered:

        It is assembled in the US. Some parts may be made in China.

    • Max from Canada asked:

      I am from canada and i do not have a liscence. Can Pyramid air Detune this gun to make it below 500 fps

      • Francisco from USA answered:

        This gun provides 0.0667788 fpe per grain per active spring coil. Without going into Hooks Law constant, as an example, take an 8.675 grain pellet, multiply by the 30 active coils and you get get approximately 17.38 fpe at 950 fps, so in order to get at 500 fps, said same pellet weight would give 4.815 fpe, which would mean you would have to cut 22 active coils, which would leave only 8 active coils plus the 2 end ones then you would need a spacer to take up the cut 22 coils length; in other words, it will cost you more to detune it than to buy a lower velocity rifle that shoots far more accurate than this one.

      • Mark from USA answered:

        We do not de-tune airguns. You would have to get a low power model in Canada
