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.

History of airguns

This report covers:

  • Before the test
  • RWS Basic
  • How does it shoot?
  • Crosman Premier Light
  • Discussion 1
  • Re-test with the “new” seal
  • Basic test 2
  • Premier Light test 2
  • Discussion 2
  • Cocking effort and trigger pull
  • Summary

Today I test the velocity of the Slavia 618. You will recall that I have two of these rifles and one seems to be performing well. That’s the one I’ll test. The other rifle I will rebuild, but we will look at that in a separate report some time in the future.

Before the test

This rifle has a leather breech seal which is indicative of a leather piston seal, as well. So I dropped about 5 drops of Crosman Pellgunoil down the barrel and stood the rifle on its butt for a few days to let the oil run down into the compression chamber and soak into the leather. It also soaks into the breech seal as it passes, softening it up so it can do the job it was designed to do. That should get the rifle into the best possible condition for a velocity test. read more

History of airguns

This report covers:

  • Recap
  • The initial test
  • Today’s test — the firing cycle
  • JSB Exact 8.44-grain
  • How I set up the Vortek kit
  • Air Arms Falcon
  • RWS Superdome
  • Cocking effort
  • Summary

Today is the day we find out what the Vortek PG3 SHO tune has done for the Beeman R10 I’m testing.

Recap

I received the rifle from a reader who wanted a rifle that had a tune done by me. I will tell all of you now that I am not an airgun tuner. I tune some of my own guns from time to time, but I don’t do it as a service. And there is absolutely nothing special about any tune I have done. This report is more a testimony of what the Vortek kit can do than it has anything to do with me.

The reader and I both agreed that a smooth-shooting air rifle was preferable to the last f.p.s. in velocity. So smoothness was what I was after, and nothing more, as long as the rifle performed within reasonable parameters. read more

This report covers:

  • 110 mainspring

  • Changing the mainspring
  • Assembly
  • Performance
  • 0.20-gram BBs
  • Rock and roll
  • 0.25-gram BBs
  • Battery
  • Summary

Today we’re going to have a little fun. I know some of you would like to work on spring-piston airguns but you just don’t want to jump into the deep end of the pool — as in buying expensive tools like a mainspring compressor and parts that may or may not work as you expect. Today we are going to change the mainspring in the SigAir ProForce MCX Virtus AEG airsoft gun, and we will do it with two Allen wrenches — nothing more! This is a job any of you can do. Then we’ll test the velocity of the gun and see what impact the new spring has made. read more

  • RWS Superdome
  • Beeman Kodiak

  • Magazine — the final test
  • Summary

Seldom has a day like this happened in this blog — and I mean that in the best possible way! This is going to be a biggie!

Start testing accuracy

Today we start testing the accuracy of the Air Venturi Avenger that I’m testing. So far the Avenger has stood up very well and I have been hoping that it’s as accurate as everyone seems to say. Well — it is! I have a lot to tell you, so let’s get started.

Bug Buster 3-12X32

I have been thinking about this test for a long time and wondering which scope to mount. The Meopta Optika6 is the best scope I own and would do very well on this rifle, but the Avenger is a lightweight PCP. How about a scope that’s suited to the concept of light weight? I mounted the UTG Bug Buster 3-12X32 on the rifle and it seems ideal to me. read more

This report covers:

  • Fill
  • JSB Exact Jumbo Heavy
  • Fill to 200 bar
  • Discharge sound
  • Discussion 1
  • Beeman Kodiak
  • Pellet feed with the single-shot tray
  • H&N Hollow Point
  • Discussion 2
  • Trigger pull
  • Summary

Today we test the velocity and power of the Diana K98 PCP rifle. According to the description on the Pyramyd Air web page, this is a 26-foot-pound air rifle in the .22 caliber I am testing. This information helps me select the right pellets to test. A pneumatic in this power range is probably best with medium-weight to heavyweight pellets, though I will also test lightweights, just so we know.

Fill

I tried to fill the rifle to 200 bar/2900 psi — the recommended fill pressure, but I waited an instant too long to shut the tank valve and the fill went to 3,000. It’s only 100 psi more. read more

  • Sleeved piston
  • Threaded spring tube
  • Breech seal
  • Cleaning
  • Piston seal
  • Tuning strategy
  • Trigger
  • Insert the piston with the new Vortek seal — tip 2
  • Last thing — the trigger box!
  • Final assembly
  • Summary

Today I disassemble the Beeman R10 and install the Vortek PG3 tuning kit. I installed one of these in the Air Arms PG3 SHO tuning kit in an Air Arms ProSport last year and the results were very positive. But this R10 is a different rifle in many ways, and I will cover that today as we go.

I am going to show you all the differences and nuances of the R10, but I can’t show everything about disassembly. If you want to see that read the 13-part series titled Spring gun tune. That was about a Beeman R1, but most of the steps are the same for the R10. I will address the ones that aren’t. read more
