Lots of knockdown power!

The special Gamo Viper Express shotshells are sized just for this .22-caliber bore. Because the loading port is sized for the shotshells, .22-caliber pellets will be loaded into a special chamber adapter you'll insert before loading. But you'll be able to quickly change back and forth between the shotshells and pellets by inserting or removing the pellet adapter.

The front sight is a bead. But we suggest that you mount a good-quality scope to extract max accuracy and help acquire further targets.

You should get 750 fps when shooting pellets and 725 fps with shotshells. You'll get 1/4" penetration into 200-lb. compressed paperboard.

The greatest benefit of this shotgun/rifle combo is the versatility that you can't find on other airguns. It's like getting two guns for the price one.

Things I liked:

Light weight, quiet, sleek and easy to aim with the front bead. Haven’t played with pellets too much tho I’m looking forward to round ball. The ability to reload the shells with custom shot is a big selling point for me. I can use tungsten or lead or even copper bb’s and get a cone of destruction down range. Power isn’t jaw dropping but neither is a standard break barrel, it’s fine for small pests and a blast for plinking.

Things I would have changed:

Seeing a second barrel or a larger power plant would have been ideal. Gamo has several multi-shot breakers and the ability to literally snap and shoot a handful of #7’s down range would take this from a Good gun to a Great one.

What others should know:

You can reload Shot shells but the seal is the hardest part to replicate. I’ve been using cleaning wads and packing foam, using the brass insert to cut the foam. You can shoot 4 .177 bb’s or rat/ bird shot,, etc. “buck and ball” is my favorite so far: 2 BB’s and 12 tungsten #7’s. If you like to tinker and plink, this is great.

Things I liked:

I like the nitro piston,the light weigh and shotshells. The gun is easy to carry. I work in an orchard and we have a starling woodpecker and sparrow problem this time of year. They birds don't stay still very long just a few seconds so a scooter riffle isn't ideal this little shotgun is very quick to aim and catch them for that second they stand still or as the try to dart away.

Things I would have changed:

There isn't much I would change, maybe the color. All my guns are camo depending on where and what I hunt. Even birds are weary of a strange black object waving around. This one will most likely be painted a few shades of green and brown to blend better into the orchard. I think having fiber optic sights would be nice atleast the bead. I set all my shotguns up with fiber optic riffle sights. This having a vent rib makes it easy to install Hi-Viz turkey sights

What others should know:

This gun is a small shotgun 10-15 yard gun. Ideal between 5-10 yards. It's not a 12g so don't expect that. If you are like me and like to use 410 then you will like this one. I feel comfortable taking pigeon sized birds at 10yrds even rabbits or squirrel at that range. Wish I had bought this sooner. Would have made the iradication of pigeoo from the packing shed quicker as they moved to the rafters in the. building and to close for quick riffle acquisition in dark tight quarters

  • Matthew from USA asked:

    What Crosman Piston was used to make this gun?

    • Wayne from USA asked:

      Stupid question i know but im new to this air gunning. Are the shells pre loaded or do you load them yourself?

      • Jacob from USA answered:

        I bought 4 packs of shotshell that are pre-loaded. I think i saw an option for empty shells that you load with your own shot with a "coming soon" annotation

      • Michael from USA answered:

        The shells that come with are preloaded plastic with #9 shot. Go to http://www.ray-vin.com/gamo/gamo.htm for reloadable. I reloaded the plastic 1 time for loading #7.5 that keep tighter patters.
