Like winning? Our FWB 800X Field Target air rifle takes world-class 10-meter accuracy and delivers it in a field target rifle. It's a dream come true for competitors who want to win.

Converting a 10M rifle into a super-accurate field target rifle used to be the job of specialized airgunsmiths. They charged a significant amount to make the conversion. Today, Feinwerkbau builds those conversions into their finest 10-meter air rifle, saving you that extra cost.

No matter how well you shoot, you'll never outgrow the FWB 800X Field Target air rifle. It has adjustments that lets the gun mold to your shooting needs. No compromises! If you missed, it's not the gun's fault. Do your part, and this air gun delivers trophy-winning accuracy.

Besides the obvious accuracy carried over from their Olympic rifles, Feinwerkbau's manufacturing has no equal. While it's cliche to say it exudes quality -- we have to say it anyway. Everything is fitted perfectly and everything works perfectly. There's nothing you have to fix, nothing you have to repair, nothing you have to tune -- nothing you have to complain about. It's about as perfect a gun as you can get.

*Our tech department got 120 shots at 11.7 ft-lbs. before the gun needed a refill. (Please note this test was done with the 11.7 ft-lbs. gun.) Their test string varied between 800-820 fps with 8-grain pellets. Tech felt it would be tighter with JSB 8.4-grain pellets or 7.9-grain pellets. The string started at 805 fps. Once the velocity dropped below 800, they stopped the testing. The test was started with a 200-bar fill. Around 150 bar, the velocity was still pretty consistent. Each gun will be different, so your mileage will vary.

Things I liked:

Once you get a scope on this, it is simply a tack driver. In a gun vise on a bench, every pellet goes into the same hole at 8 meters. Every kind of pellet from special target to bulk field were the same - they hit the exact same hole. The trigger is butter - no adjustment required. With the internal regulator, the chrony shows very consistent velocities from 3000 psi down to 1000 psi. 8.64gr avg 780 fps, 10.65gr avg 720 fps. The fully articulated stock has many adjustments and takes some time to fit properly - but when you do, this rifle becomes an extension of your body. A great rifle so far. Can't wait for the 50 meter testing.

Things I would have changed:

The price of course. FWB makes amazing rifles and charges a good deal for that amazement factor. And it is worth every penny.

What others should know:

At this level the performance of rifles is nearly identical between manufacturers and the choice of the shooter is essentially that of personal preference. I like FWB, how they are made, how they operate, and how they fit. They have a long history of producing durable, serviceable rifles (and spare parts) that cannot be out-shot by a human. Simply put, in a competition, this rifle is not a variable to be considered - it WILL put the pellet where it is aimed when the trigger is pulled. I will most definitely be handing this rifle down to my 11 year old son when the time comes for me to stop shooting it. Oh yeah - did I mention when paired with a Hawke Sidewinder 30 SF 8-32x56 scope, it looks like something from Star Wars and gets mostly "WTF" as the first comment? Mostly by onlookers not familiar with the sport of field target and primarily due to the scope with the sunshade attached being only 4 inches short of the barrel tip.
