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.

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!

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.

Umarex Throttle air rifle: Part 3

Throttle
Umarex Throttle offers a lot for a little money.

Part 1
Part 2

This report covers:

  • StopShox
  • Mount the scope
  • Accuracy
  • RWS Superdomes
  • Crosman Premiers again
  • JSB RS
  • Some other pellets
  • What next?

Today we look at the accuracy of the new Umarex Throttle air rifle. You may remember that I was very pleased with the performance of this new air rifle, up to this point. If it is also accurate, we have a winner.

StopShox

This rifle contains the StopShox mechanism that takes the sting out of shooting a gas spring. That unit works, because the Throttle definitely does not sting.

Mount the scope

The Throttle came with a 3-9X32 scope and 2-piece scope rings. The Throttle has a Picatinny rail they call the LockDown mounting system. It’s mounted to the top of the spring tube, and the rings are Weaver, so mounting the scope was fast and easy. The optics are clear and this scope has AO (adjustable parallax) that adjusts down to 10 yards.

Before we begin I want to tell you about a blog series I will start this week. I have the new Air Venturi air compressor on hand and I used it for the first time yesterday. It works so well that I’m jumping the line to get the report started. You can expect to start reading about it this week.

The 2017 SHOT Show was the biggest show I have ever experienced for airguns. Some manufacturers like Crosman and Umarex brought out many new gun models and related products that are really different. Others brought out only one of two items, like the Gamo Swarm Maxim, but they are so significantly different that they deserve to be recognized. My work is cut out for me this year!

  • 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 AR8 N-TEC air rifle.

Part 1

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.
