  • Inexpensive?
  • Sights
  • Scope base
  • Trigger
  • Firing behavior
  • Summary

The full title of the rifle we are looking at today is the Diana AR-8 Professional Success. That’s right. Apparently the Germans have hired Koreans to name to their airguns. Remember Shin Sung — Good Luck for Dignified Masterworks?

The rifle

The rifle I’m testing is a .22, but it also comes in .177. The serial number I’m testing is 20067725. The name AR8 is derived from the Blaser R8 Professional bolt action rifle, though that firearm bears little physical resemblance to this air rifle. Perhaps they mean similar in performance within the airgun world.

The AR-8 has a gas piston unit — the Diana N-TEC piston. That is a unitized piston assembly with an internal gas spring. I tested one before in the 340 N-TEC, and I know how nice it can be. Let’s hope the AR-8 tests just as well.

A history of airguns

This report covers:

  • Description
  • Sights
  • Taploader
  • Trigger
  • Not much information
  • Summary

Here we go! I told you I would be reporting on those airguns I acquired from the Gun Broker website. This is the first of them. The Mauser 300SL is an underlever spring-piston target rifle that is almost a 10-meter rifle, but not quite. After examining it, it appears the people who made this rifle were concentrating more on the style of the zimmerstutzen, rather than a modern 10-meter target air rifle. I’ll explain as we go along.

Description

The 300SL is an underlever that looks something like a Feinwerkbau 300. But there are many differences. For starters, this is a recoiling air rifle. No attempt was made to cancel the recoil. Given that it was sold in the 1980s, that takes it out of the running for 10-meter competition. The FWB 300 was already obsolete in the ’80s.

The cobbler’s children have no shoes!

This report covers:

  • B.B. needs help!
  • What about my Diana 27?
  • Ten yards
  • We have lost 95 percent of shooters!
  • Blue Streak
  • Spoiled?

B.B. needs help!

Before we begin today’s report, I need to ask for some help. In fact, today’s report drove this request. I was going to write about the Rockin’ Rat target, Part 2, and I wanted to show you a short video of how it works. The main thing about this target is the way it works, and trying to tell you about it is like trying to describe the taste of salt.

I can film the video, but I’m not yet familiar enough with the editing software to edit it efficiently. Pyramyd Air can’t help because they are working full time on their projects.

What I need is someone who can edit short videos for me. If I could find someone to do that there could be a lot more videos on this blog. The person should be familiar with the requirements of You Tube, because that’s where the videos are hosted.

This report covers:

  • Sight-in
  • JSB Exact Jumbo 15.89 grains
  • What to do?
  • Changed my hold
  • H&N Baracuda Match 5.53mm
  • Evaluation

It’s been a long time, but today is the 25-yard accuracy test for the Walther Parrus with wood stock I’m changing things today, so try to keep up.

I installed the Sun Optics Tactical Hunter First Focal Plane Scope in BKL 30mm Double Strap high rings. I looked at the Parrus barrel alignment before mounting the scope and noted that the test rifle has a major barrel droop. I therefore shimmed the rear ring, but I thought that would not be enough, and I was right. This Parrus I am testing droops as much as any Diana breakbarrel I ever tested, so consider that when you select a scope mount.

Time out with B.B.

This report covers:

  • New old airguns
  • Tune in a Tube
  • Serendipity
  • More serendipity
  • More stuff
  • Parrus inletting is tight!
  • Summary

I needed to pause from testing airguns and related products today to tell you about some real neat things that are happening in my world — and by association — in this blog.

New old airguns

I guess it’s no surprise that the blog’s history section is very popular with a lot of readers. It is for me, too, because I get to see airguns I have only seen in the Blue Book of Airguns or in old references. I now watch Gun Broker and some of the online airgun sales sites, plus whenever I go to an airgun show I’m always looking to buy something we haven’t yet seen. The Crosman 600 pistol and the BSA Meteor Mark I both came from the recent Texas Airgun Show, and you have seen what’s been done with them.

  • Mainspring
  • Lubrication and assembly
  • Trigger
  • Cocking effort and trigger pull

  • Discussion

Today I am disassembling the BSA Meteor Mark I for cleaning, inside and out. I’m going to get rid of that pesky rust, plus all the grit I saw when the gun was apart last time. I’ll also be able to tell you how well Tune in a Tube had spread throughout the action,. which is something most owners will never know. There is a lot more to today’s report, so let’s get started.

Disassembly

This time I knew exactly how the Meteor would come apart. Even the trigger that I told you is different from the trigger in my Meteor Mark IV was easy to disassemble, although I will come back to it at the end of the report.

Some talk about airgun lubrication: Part 1

by Tom Gaylord
Writing as B.B. Pelletier

This report covers:

  • Why do we lubricate?
  • The Meteor’s needs for lubrication
  • Leather piston seals
  • Velocity
  • Watch the performance
  • Synthetic piston seals
  • Summary
  • Other lubrication requirements

Yesterday a reader asked why I bothered with Tune in a Tube. Why didn’t I just clean the Meteor Mark I when I had it apart, lubricate with moly grease and be done with it? That tells me there are a number of readers who don’t really understand what is involved with airgun lubrication. So today I thought I would discuss it a little.

Why do we lubricate?

This is a good place to start. In fact, from the reader’s comments, it seems to be at the core of misunderstanding. Don’t we just lubricate to reduce friction?

Friction is a principal reason for lubrication. But there is more to it than that. Sometimes we want to reduce friction by a certain amount, while retaining some part of it that’s needed for proper operation. Otherwise, moly (molybdenum disulphide) would be the answer to everything. Some airgunners think it is. The reader who wrote the comment that got me started on today’s topic said that very thing — that I should just clean the Meteor’s parts and lube everything with moly and be done with it.
