The Air Javelin from Umarex.

This report covers:

More to test
What are the holes for?
Remove the old 88-gram cartridge
Lots of gas!
Install the adaptor
Cock the gun!
Don’t do as BB does!
Adjust the dot sight up
Discussion
Summary

Today I shoot the Umarex Air Javelin with a dot sight optic. My UTG Reflex Micro Dot was mounted elsewhere so I mounted a Tasco Pro Point red dot sight.

The Air Javelin accepted the Tasco Pro Point without a problem.

More to test

I didn’t tell you this but I asked Umarex to send me a 12-gram CO2 adapter so I could test the AJ with 12-gram cartridges. Some readers had asked about that possibility and since Pyramyd Air doesn’t carry the adapter, I went straight to Umarex.

Several Umarex airguns including the Air Javelin use this adapter that switches the power source from 88/90-gram CO2 cartridges to 12-gram cartridges. read more

A little about o-rings

An assortment of o-rings.

This report covers:

History
Flexibility is key
O-ring failure
O-rings as a face seal
O-ring-assortments
Hardness
Some o-ring facts
The seats or channels they sit in help o-rings work!
O-rings used other ways
Summary

An o-ring is a donut-shaped elastomer (pliable) seal that performs sealing functions for hydraulics and gasses. Airguns use o-rings a lot, and for different purposes. They help us enjoy our hobby with a minimum of fuss. But what do we know about them?

History

The first patent for an o-ring was by the Swedish inventor, J.O. Lundberg. It was granted in 1896. Not much is known about him, but Danish machinist, Neils Christensen who came to the U.S. in 1891, patented the o-ring in this country in 1937. No doubt his work originated from his development of a superior air brake that Westinghouse, a leader in air brake technology since George Westinghouse invented the first fail-safe railroad air brake in 1869, gained control of. In World War II the U.S. government declared the o-ring a critical mechanical seal technology and gave it to numerous manufacturers, paying Christensen a stipend of $75,000 for his rights. Long after the war was over and he had passed away his family received another $100,000 read more

The Air Javelin from Umarex.

Part 1
Part 2

This report covers:

Before we begin — the inside diameter of the gas tube
The test
Setup
First shot
Aiming
Loading
Shot away!
Move target to 11 meters
Shot two
Shot three from 10 meters
Back up to 17 meters
Adjusted the rear sight one last time
Shots 5 and 6
End of the test
Shots 7 and 8
Summary

Today I shoot the Umarex Air Javelin airbow for accuracy. I know that a lot of readers have been waiting for this! This will be an accuracy test, but as I said before, the AJ is such an important shooter that this report is going to proceed along different lines.

Before we begin — the inside diameter of the gas tube

Oh my, have some readers obsessed over this! They are busy redesigning the AJ the way it should have been, if only Umarex engineers were smart enough to have recognized it! I hear from AirForce all the time that they wish they were as clever as the people who redesign their airguns. But they know they aren’t, so they just let it ride. read more

Umarex Air Javelin airbow: Part 2

The Air Javelin from Umarex.

Part 1

This report covers:

However
The “barrel”
Not a toy!
Sights
Front sight
Rear sight
Adjust the stock
Install the cocking handle
Charging
One fact to bear in mind
Summary

At least one of you readers is really interested in the Umarex Air Javelin, just as I am, so today is Part 2. However, because this is an arrow launcher, this Part 2 will be a little different. I normally test velocity in Part 2, but the Air Javelin is better tested outdoors for that and today the temperature here in sunny Texas is 36 degrees, F. Yes, we have bright sunshine and the temp is supposed to rise to 62 late this afternoon, but my testing and photography work gets done in the morning, so the cold is hampering me.

However

That doesn’t mean I can’t shoot the Air Javelin (hereafter called the AJ) indoors. In fact, by shooting it indoors I will get a really good idea of how loud the report is. Remember that I could not hear it when I shot it at Industry Day at the Range in January. I’m making this report up as we go, so let’s get going! read more

Not an airgun?
Low cost
Industry Day at the Range 2020
Noise?
Description
Action is ambidextrous
Performance
Will it accept air?
Size and sights
What’s the purpose?
Summary

Well, lookie, lookie, who’s got the cookie! I write about airgun manufacturers putting peep sights on their guns yesterday and today’s star — the Umarex Air Javelin — has them! Not only that, the Air Javelin (AJ) is a thousand-dollar airgun selling for $170! Or at least it will be when they come in.

Get ready

I’ve been sitting on this report for over a month for a couple reasons. The main one is the AJ that isn’t quite on the market yet. I don’t like to write about airguns you can’t get, but I expect this one to be available soon.

Not an airgun?

Is the AJ really an airgun? We can get into a long discussion about that, and I expect we will, but here is my opinion. The AJ shoots arrows, so it’s definitely not a BB or pellet gun. And it runs on CO2, so we can have that discussion, as well. read more

Sig Sauer P365 air pistol: Part 4

Sig Sauer P365 BB pistol.

Part 1
Part 2
Part 3

This report covers:

The test
The first shot
Sig BBs
Discussion
New CO2 cartridge
Crosman Black Widow BBs
What I’m up against
The trigger
Dust Devil BBs
Summary

Today we look at the accuracy of the Sig P365 BB pistol. So far this gun has been performing as it should. I just hope it will stay on the paper at 5 meters. There are two reasons I say that. First, with guns that have a short barrel, ANY movement of the gun/barrel causes large movements of the shots downrange. Short-barreled handguns are just as accurate as handguns with long barrels — they are just harder to shoot accurately. And second, with a sight radius (distance between the font and rear sight) of just a few inches, ANY amount the sights are off will be exaggerated downrange. read more

The XD-M BB pistol from Springfield Armory.

Part 1

This report covers:

Compact pistol
The grip
Installing the CO2 cartridge
Not a small pistol
The loading assist — doesn’t!
Velocity Air Venturi Steel BB
Dust Devils
Slide does not remain open
Smart Shot
Shot count
Blowback
Trigger pull
Evaluation
Summary

I don’t encounter many airgun copies of firearms that I am unfamiliar with, but the Springfield Armory XD-M Compact blowback BB pistol is one. So my report will be a first hand observation of all the features I notice about this handgun.

Today is the day I test the velocity of this BB gun and we will get right to it, but first I need to make a couple observations. They came from installing the first CO2 cartridge in the pistol.

Compact pistol

In Part One I told you I was testing the smaller version of the Springfield Armory XD-M pistol. There is a larger pistol whose barrel is 4.5-inches long. The pistol I’m testing has a 3.8-inch barrel. On the cover of the owner’s manual Air Venturi refers to this one as the Compact. The other one they call Full-Size. read more
