Rail Lock Compressor
The Air Venturil Rail Lock spring compressor is compact.

Part 1

This report covers:

  • Attaches to scope rail
  • Enter the R8!
  • R8 out of the stock
  • Remove the Rekord trigger
  • Unscrew the end cap
  • Install the mainspring compressor
  • Removing the end cap
  • One last photo
  • Assembly
  • Evaluation so far

Today I start testing the new Air Venturi Rail Lock spring compressor. Many of you have expressed an interest in this tool, and I want to test it as broadly as possible, because all airguns are not made the same.

Attaches to scope rail

This compressor attaches to the scope rail on your airgun. It will work on both pistols and rifles — as long as there is a scope rail to attach to. It attaches to both 11mm dovetails and Weaver/Picatinney dovetails. The rails have to be close enough to the rear of the spring tube to allow the compressor to work, but that will become clear when you see the pictures.

2017 Findlay airgun show: Part 2

Part 1

This report covers:

  • Here we go
  • Wire-stock Daisy
  • What is Findlay?
  • 10-meter airguns
  • Sold some stuff
  • What about a big bore?
  • Were modern airguns there?
  • Toys, too
  • The Larc
  • There is more

Here we go

Yesterday’s report was just a lead-in. Today I want to tell you about the show. First — it was large. It was held in two rooms, with hallways and out-of-the-way nooks also being used. And every table was filled! This was a show you could spend many happy hours seeing just one time. And the tables changed over time, so your second time through things were different. People bought stuff from the public that attended, plus they brought out some of the stuff they didn’t unpack in the beginning. It was an all-day affair!

Findlay crowd
This is a long shot of the main show room. The floor of this room is an indoor soccer field, and it was filled!

Air Venturi Rail Lock spring compressor: Part 1

Rail Lock compressor
The Air Venturil Rail Lock spring compressor is compact.

This report covers:

  • Attaches to the scope rail
  • Let’s look at the unit in detail
  • How shall I test it?
  • Developed for gas spring guns
  • Installation
  • The coolest feature
  • Quirks
  • The price

Today we start looking at a mainspring compressor that’s very different from any other. The Air Venturi Rail Lock spring compressor is a compact 1.5-pound unit that attaches to the scope rail of the gun being disassembled. The threaded rod is then pressed against the end cap of the rifle — whatever configuration that might take. From that point this compressor works the same as any other, but in the next few reports I will show you in detail, plus today we will look at its design very closely.

Attaches to the scope rail

Right off the bat you might be wondering if this unit will fit most spring-piston airguns. As long as they have a scope rail either cut into the spring tube or attached, it will work. There are a few vintage spring rifles and pistols that don’t have rails like the Haenel model 28 pistol and some Diana model 27 rifles, and this compressor won’t work without a rail. But the majority of spring rifles being sold today, plus a number of spring pistols, do have a scope rail. On them the compressor should work well.

Why own a chronograph?

by Tom Gaylord
Writing as B.B. Pelletier

This report covers:

  • No preaching
  • Evaluate an old airgun
  • Test pellets
  • Evaluate a tuneup
  • For detailed tuning and product development
  • What it isn’t

Today is my cataract surgery. I don’t know how well I will be able to function online for the next several days, so will you veteran readers please help the new guys? I know you always do, but I’m just telling you what’s happening.

If you have read this blog for very long you can answer the title question for yourself, because I write about chronographs all the time. I use them for big things like testing the health of a new acquisition (the Sharp Ace Target and the Sheridan Supergrade), and things more subtle (testing the Air Arms Galahad).

No preaching

I used to preach about when to use a chrono and when not to, but I’m not going to do that today. Use it whenever you like and for whatever reason suits you.

2017 SHOT Show: Part 4

  • Crosman
  • Benjamin Wildfire
  • Marauder Field & Target
  • Adjustable regulator?
  • 1875 Remington revolver
  • Best for last
  • Whew!

Crosman

Let’s continue with our look at the new airguns and things at the 2017 SHOT Show. We will begin with Crosman. While I was gawking at the guns, Jesse Caster from Crosman came up and showed me everything you are about to see.

Benjamin Wildfire

The first thing I did was examine the new Benjamin Wildfire rifle. Based on the famous Crosman 1077 that is itself a copy of Ruger’s iconic 10/22 rifle, the Wildfire feels just as light as the CO2-powered rifle. I was hoping it would.

Benjamin Wildfire
New Benjamin Wildfire looks very similar to a 1077. The biggest difference is the longer reservoir.

That tells me that the trigger will feel the same. The 1077 trigger both cocks and releases the striker and advanced the 12-shot circular magazine to the next chamber. That’s why I keep insisting it’s a double-action revolver. The feel of the trigger is exactly the same as that of a double action revolver.

Diana model AR8: Part 4

Diana AR-8
Diana AR8 N-TEC air rifle.

Part 1
Part 2
Part 3

  • New Diana scope base
  • Droop?
  • The test
  • Baracuda Match 5.53mm heads
  • Firing behavior
  • Better artillery hold
  • JSB Exact Jumbo
  • RWS Superdome
  • Notice all three groups
  • Conclusions

This report has taken a long time to write. I wanted to test the Diana AR8 from 25 yards with open sights, but my sighting eye has degraded to the point that I can’t do that. The AR8 is also very hard to cock and it would be too much trouble to shoot it left-handed, so I scoped it for today’s test. I used a 3-12X40 UTG scope that’s no longer made.

New Diana scope base

As you may remember, Diana changed the installed scope bases on all their spring rifles a few years ago, negating the aftermarket bases that were designed for them in the past by UTG. There are still hundreds of thousands of those vintage rifles that those bases fit, but the new base on all their spring rifles will not allow the old droop-compensating UTG mount base to be installed.
The problem is — Diana’s base on the rifle doesn’t accept a scope ring set very well. I wanted to use a base that accepted Picatinney scope rings, because of the heavy recoil of the AR8, but Diana doesn’t provide a ring like that, nor would it fit their base if they did.

Umarex Throttle air rifle: Part 2

Throttle
Throttle rifle from Umarex brings a lot of value to the table.

Part 1

This report covers:

  • Cocking effort
  • RWS Superdomes
  • RWS Hobby
  • H&N Baracuda Match
  • Trigger pull
  • Stock flex
  • Evaluation

Today we look at the velocity of the Umarex Throttle air rifle. As a quick reminder, I am already impressed by this rifle, just from the brief handling I did in Part 1. Today should advance that. Let’s get right to it.

Cocking effort

It would be easy for me to measure the cocking effort, then “guess” in writing that it will be somewhere close to that. I don’t do it that way. When I guess, I haven’t measured it yet. Today is when we both discover what the real cocking effort is. I guessed it would be around 33-36 pounds of effort. When I measured it on my bathroom scale the number was 28 lbs. Less than I expected. I am impressed!
