1077 rifle
Crosman’s 1077 RepeatAir is a classic.

This report covers:

• Some old business — trigger-pull
• Today’s test
• First up — Crosman Premier lite pellets
• Air Arms Falcon pellets
• H&N Finale Match Pistol pellets
• Evaluation so far

Today we’ll look at the accuracy of Crosman’s 1077 CO2 rifle. Just as I said, it’s pretty impressive for an air rifle in this price range.

Some old business — trigger-pull
One of our readers asked me if the 1077 trigger-pull would be too heavy for a 9-year-old girl. I said it would on a new gun; but that I have an older gun whose magazine mechanism is broken-in, and I thought it would be okay.

1077 rifle
Crosman’s 1077 RepeatAir is a classic.

This report covers:

• The 1077 is a lookalike
• Ruger’s 10/22 is the most popular .22 rimfire
• Crosman often copied popular firearms
• 1077 debuted in 1994
• 1077 basics
• Magazines & clips (they’re not the same!)
• The BIG lesson (miss this & you might mess up)
• CO2 powerplant
• Summary
• Ft Worth airgun show update

I went around and around about the topic for today’s report. There are several new airguns I wanted to start reviewing, and several vintage guns I also want to look at. But the bottom line is that I had to go with Crosman’s 1077 CO2 rifle. Why, you might ask? Because this rifle is one you need to know about. It’s a classic for many reasons. Perhaps, the first one will surprise you.

Today, we’ll test the Umarex Fusion CO2 rifle at 25 yards. And today was also supposed to be the day I tested how long you have to wait to remove the CO2 cap after exhausting the gas. That’s not going to happn, though; because when I took off the CO2 cap to install 2 fresh CO2 cartridges, I noticed the o-ring was damaged pretty bad. So bad, in fact, that it might not work any longer. I switched it for a common black Buna o-ring of the same size and then charged the gun. At the end of this report, I’ll tell you how that works.

The original o-ring had these two damaged spots. I thought it might leak, so I replaced it.

Today is the first accuracy test of the Umarex Fusion CO2 rifle. It comes one part late because we spent time looking at the CO2 cap, the adjustable trigger and the power adjuster in Part 3. The power adjuster is straightforward — twist the screw in and increase the striker spring tension to increase power. The trigger, we learned, is adjustable, but the safety slider prevents a very wide range of adjustability. You can modify it if you choose, but I don’t recommend it; and it will void any warranty on the gun. Blog reader mikeiniowa explained how it’s done, but he said to use caution — and I don’t intend doing it to the test gun.

Part 3 of most reports is the day we test accuracy. Sometimes, we test accuracy more than one time; but Part 3 is usually when we test it for the first time. But that isn’t going to happen today. Blog reader mikeiniowa told us that the Umarex Fusion CO2 rifle rifle has both adjustable power and an adjustable trigger. I said I would look at that in detail when we got to it. Well, today’s the day.

The CO2 cap assembly
Before I get to either of those things, however, I want to talk about the CO2 cap in detail. I promised I would show you how this works, so I’m going to take it apart and show you the internals. I’ll also try to describe why the cap is as complex as it is.

Today, we test the Umarex Fusion CO2 rifle for velocity and several other things you readers are interested in. You may remember that in the first part I had a problem with the rifle not sealing when I loaded the CO2 cartridges. Blog reader mikeiniowa nailed the problem with the Fusion CO2 cap. The part that contains the piercing pin was partially unscrewed and was, therefore, longer than it should be. It was piercing the cartridges before the o-ring was in position to seal the gun. So, a lot of gas leaked out; and, because the o-ring absorbs CO2 and swells when it does, it also prevented the cap from being screwed down tight.
