Today I mount the scope that came with the Umarex Forge and I’ll step back to 25 yards to test the accuracy. Part 3 was a blessing because I found two good pellets and I also learned the best way to hold the rifle That sped up today’s preparation time a lot.

Mounting the scope

Mounting the scope was easy. The rings have two screws per cap, so there is no need to tighten them in any pattern and the base is a Weaver that fits the Forge’s Picatinny rail well. Since I knew the Forge doesn’t recoil too much, I also knew the mounting screws only needed to be snug.

Sight in

Once the scope was mounted I shot a single shot from 12 feet and discovered the rifle was hitting high and to the right. I adjusted the scope and fired several shots to get it into the bull at 25 yards. It took six shots to get the scope adjusted where I wanted.

The test

I shot from 25 yards off a sandbag rest, using the artillery hold. My off hand was stretched out as far as it would comfortably go under the forearm.

Poor scope

The 4-32 scope that’s included with the rifle is another tent peg! The image at 25 yards is blurry and I could not adjust the eyepiece to get the reticle lines sharp. I had to guess where they intersected. The only good thing I can say about this scope is it adjusts correctly and without stiction. In other words, when an adjustment is made, you don’t have to fire a shot to get the scope to move. It moves with just the adjustment.

JSB Exact RS

The first pellet was also the one I used to sight in — the JSB Exact RS dome. I checked the first shot with the spotting scope because the 4-power scope on the rifle was both too weak and too blurry to see the pellet holes in the black. After that I didn’t look at the target again until I went downrange to change it.

Ten JSB RS pellets made a group that measures 0.973-inches between centers. Nine are in 0.674-inches. That’s not too bad, considering the poor scope. Do I think this rifle can do any better? Probably, but not by a large amount. I think we are seeing its representative accuracy here.

Forge RS group
At 25 yards the Forge put 10 JSB RS pellets into 0.973-inches. Not bad!

Falcon pellets

I tried the Falcon pellet from Air Arms next. It is the other pellet that did well at 10 meters in the last test. At 25 yards the Forge put 10 Falcons into 0.826-inches. That’s an even better group, overall, but the one shot that opened the JSB group might have been due to the scope.

Forge Falcon group
The Forge put 10 Air Arms Falcon pellets into 0.826-inches. This is a good one.

H&N Hammer pellets

For the final pellet I decided to try the H&N Hammer. The description says these are for plinking, when pinpoint accuracy doesn’t matter. Looking at the 1.536-inch group they produced, I would have to agree with that sentiment. The group is vague and open, unlike the other two.

Forge Hammer group
Ten Hammer pellets went into 1.536-inches at 25 yards.

Don’t care for the flex

As I shot this test I could feel the synthetic Nucleus Rail flex every time I cocked the rifle. I don’t care for that feeling. It, along with the heavy trigger, detract from an otherwise world-class breakbarrel spring rifle.

Evaluation thus far — world class!

And yes, that is my evaluation of this Forge air rifle. It is definitely world class. It offers accuracy, decent power and good looks at a price no other air rifle has been able to match. Cocking is easy and the firing cycle is relatively calm. It has adjustable open sights that are easy to use.

On the down side the trigger pull is too heavy and the Nucleus Rail flexes when the rifle is cocked. For all this rifle offers I can tolerate those few things.


I will mount a better scope on the Forge and test it one more time. I think this rifle deserves a fine scope, to compliment its accuracy.
