Well I played around with the new Nitro 17. The barrel looks like it might be stainless steel, but hard to tell because it it incased in plastic.
Quit a few different things on this rifle from the normal Gamo, barrel 'O" ring is in the breach not the pivot block as normal Gamo practice, and now there is a retaining pin in the front of the breach, looks like they just took a tube and plugged it with the reciver for the barrel pivot. This should make it a much nicer thing when honning the bore for a new seal, the size is the same as all the other gamo's in the 1000 series. By the looks of it the rest the Gamo's with the plastic shrouded barrels should be about the same. I know the Shadow Sport is along the same lines as the Nitro 17. with the plastic shrouded barrel.
They changed the way the cocking lever is guided, instead of a roller they now have a button in the bottom of the stock that the cocking lever rides on, you could put a Nitro stock on a Shadow , but not the other way around, there are no ledeges for a roller in the Nitro stock. I like the stock with the CFX style fore grips.
Rifle is a lite one with the plastic stock and barrel, even with a heavy scope. I tried the 3X9X40 BSA and I didn't like it so I put on a big Barska 30mm 3X12X52 , 24 onces of scope and mount, and rifle still feels lite. It has the normal Gamo twang but not quite as bad as my shadows when I got them.
Gamo says it will shoot 1050 with PBA ammo and 800 with lead and by golly they are right !!
After 25 wadcutters to clean out the oil I shot it over the crony and with PBA 1062 average, and with 7.9 CPL's 794 average. Not bad at all and the thing puts down good groups at 35 yards "with lead" less that an inch.
I just wonder what happened to those one piece scope mounts? this one came with plain mounts and a scope in a box, but it does have a hole in the reciver to lock down the scope stop.
It's a fun rifle to shoot and would be a great rifle for a lady because of it's lite and fairly easy to cock. I'll keep it , it's a great little backyard plinker.
