  • A hard job
  • Summary

Today we learn who is the winner of the Design an Airgun contest. It began on September 10 and was supposed to end at the end of the month, but several readers asked me to extend the closing, so I did. The contest ended last Friday, October 16.

Several entries

There were several entries. Some were blue sky dreams and nothing was built. I didn’t take them seriously. But some folks submitted more than one entry and they built all of theirs. I considered everything on the basis of the contest rules, which were:

1. I’m guessing it will be a BB gun, but it doesn’t have to be.
2. I’m guessing it will be a smoothbore, but again, it doesn’t have to be.
3. When I say build an airgun, it doesn’t have to work with compressed air.
4. It can be any kind of powerplant — so long as it doesn’t use an explosion to launch the missile.
5. The winner would be the niftiest design that the most people could build.

Umarex Air Javelin airbow: Part 5

Part 4

This report covers:

  • Quick review
  • More arrows
  • Setup
  • Sight in
  • At 10 meters
  • At 20 meters
  • Raise the sight
  • Summary

Today I shoot the Umarex Air Javelin at 20 meters with a dot sight that has been sighted in. You finally get to see the sort of accuracy that I saw at the SHOT Show in January. The range there was set up for about 25 yards and it seemed like the arrows all went to nearly the same place! You will see that today.

Quick review

Part 4 was a test with a dot sight too, but I also tested the Umarex CO2 adaptor that allows you to use two 12-gram CO2 cartridges. Unfortunately the Tasco Pro Point dot sight I used for that test could not achieve the elevation that was needed to hit the target at 20 meters. I also shot wide of the target bag when I shot an arrow that had been damaged in the rear from a Robin Hood. I didn’t know it was damaged until I pulled it from the fence and examined its base. read more

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. 

Air Javelin 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.

Air Javelin 12-gram adapter
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.

Part 1
Part 2

This report covers:

  • Sights
  • Dot sight
  • Vibration
  • Safety
  • Hunting limb
  • Sight-in
  • Group
  • Damage to one arrow
  • Stopped at this point
  • Observations
  • Fletching
  • Next test
  • Summary

Wow! It has taken me a looooong time to return to the Sen-X AR-6 Tactical Arrow Repeating Crossbow. Most of the reason for the delay was the weather that never quite cooperated, but when I tried to do a test at the end of February the problem became something else altogether.

Sights

In Part 2 I showed you that the sights on the bow are primitive. There is a front post, but in the rear there is nothing to align it with except the silver spring latch on the magazine cover. There is a red laser built into the AR-6, but it cannot be seen in daylight beyond about 10 feet. With just those crude sights I managed to shoot the bow fairly well, but I wondered what better sights would do. read more

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

History of airguns

This report covers:

  • The first compound bow
  • A gift!
  • History
  • Description
  • Made for a southpaw!
  • Bow data
  • Tuning the bow?
  • Dimensions
  • Value
  • Summary

I was looking for something completely different  for today’s report. I was temporarily bored with my list of airguns to cover and I didn’t feel like another rant, so today I am reporting on something that is in the shooting sports, but a long way from airguns — the world’s first compound bow.

Discovery

About two months ago, and just before my town locked down for the Covid-19 pandemic, I was in my favorite pawn shop, looking to see what new/old things might have come in. Naturally I searched the whole store, as I always do. There are things on my watch list, like a long-bladed plain-head screwdriver with a wide tip, that I’m always searching for. I didn’t see anything interesting until the very end, when I spotted a strange and simple-looking compound bow standing in the corner by the gun rack. It looked homemade so I asked to see it. I wasn’t interested it it beyond seeing how it had been made. It looked for all the world like something that had been built from plans published in Popular Mechanics. read more


Umarex Air Javelin airbow: Part 2

Umarex Air Javelin
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
