Part 1
Part 2

This report covers:

  • Gun returned in February
  • Oiled the gun
  • Installed the cartridge
  • Sig BBs
  • Blowback
  • Daisy Premium Grade BBs
  • Dust Devil Mark 2 BBs
  • Shot count
  • Average for the first string of Dust Devils
  • Fresh CO2 cartridge
  • Trigger pull
  • Realism
  • Summary

A lot of time has passed since Part 2 of this report. The Sig P365 BB pistol I was testing back in early September of 2019 failed after the velocity test, so I never got to perform the accuracy test. I sent it back to Sig at their request. I then had several conversations with Ed Schultz, who was still working at Sig at that time, and I learned a few things. Most significantly, the valve in this pistol is very small because of the pistol’s overall small size. That makes this valve more sensitive than most CO2 pistol valves. There isn’t as much room for the gas to flow so it tends to flow directly out of the cartridge and through the gun, rather than through a longer gas channel inside the valve. There is a channel but it is very short. That means things either have to work right or perhaps not at all. read more

Part 1 — resealing the end cap

Over to you, Ian.

Crosman Mark I and II reseal

Ian McKee 
Writing as 45 Bravo

This report covers:

  • Disassembly
  • Bolt removal
  • Hammer spring
  • Remove trigger guard
  • Remove the valve
  • Prep and assembly
  • The 4 o-rings in the pistol
  • Piercing cap o-rings
  • Assemble the pistol in the reverse order
  • Test the function

So, your Crosman MK1 is still leaking, even after you replaced the seal in the piercing cap as we covered in an earlier blog. 

There are only 4 o-rings in this pistol, only 3 have constant gas pressure on them when the gun is charged, and 2 of those are in or on the piercing cap assembly, and those we already covered.  read more

What? Another S&W 78G? BB — we know you love this air pistol but you just finished a 5-part blog on one last June! Enough already!

Behind the curtain

There is a good reason why I needed to write this blog. I spent 10 hours yesterday (all day Friday) and this morning (Saturday) trying to tune my Diana 27S air rifle so I can report on it. At this point I have one piece of advice to anyone trying to tune one of these rifles. DON’T REMOVE THE TRIGGER BLADE ASSEMBLY!!! Eight and one-half of those ten hours have been spent trying to reinstall the trigger assembly and it still isn’t in! I will get the rifle back together and give you a great report on the tune and troubles I had in good time, but if a blog was going to be published today it had to be something else that was quick and easy. read more


Range days at the 2020 SHOT Show

It’s over

Media day at the Range

Constant Acceleration Pneumatic Arms

Light gas

Not done yet

That’s all

I went to two range days this year. Sig Range Day was on Sunday and Industry Day at the Range was Monday. Both are for the media, so we get to see and possibly shoot the guns they are showing at SHOT. I say, “Possibly” because the guns don’t always cooperate. I have seen several that failed to function on range day. That’s either because they were rushed through production or sometimes it’s just bad luck. read more

Crosman Mark I and II reseal

by Ian McKee
Writing as 45Bravo

This report covers:

  • Just kidding!
  • Four major changes over the years
  • I got this one cheap
  • It’s mine!
  • Bringing it back to life
  • BB’s end cap
  • Resealing both caps
  • How did it go?
  • Outer barrel removal
  • Wrong o-rings

Back in December 2018, and January 2019, B.B. reviewed a classic Crosman Mark I pistol in .22 caliber.

There were many comments about how it worked internally, and how the power adjuster worked, so today I thought I would give you a little peek inside the gun.

Mark II disassembled
Here is your peek of a disassembled pistol. This is actually a Mark II I photographed some time back. The parts of the two pistols are identical except for those pertaining to the caliber.

Thank you, that concludes today’s blog.

 

Just kidding!

I could not do that to you. Here is a synopsis to refresh your memory.

The Crosman Mark I and Mark II (.22 and .177 calibers, respectively) pistols are airgun versions of the classic Ruger Mark I and Mark II .22 rimfire pistols. They share the same grip angle, sight profile, and overall profile of the iconic Ruger rimfire pistol.

Ruger Marl 1
Ruger’s Mark I pistol.

All Crosman Mark air pistols retained an adjustable trigger throughout their production run, which was 1966 to 1986, but had other changes in their design over the years.

Four major changes over the years

The flip-style piercing cap was changed to a button-style piercing cap, similar to what’s found on the Smith & Wesson 78/79-series air pistols.

The metal bolt guide that was secured in the frame by a screw on either side below the rear sight was changed to a plastic bolt guide that is retained by 1 screw that’s hidden under the rear sight blade.

The power-adjusting screw that was located under the barrel was eliminated.

And to hold the grips they changed from using screws with countersunk heads to screws with flat heads, as shown.

Mark I grip screws
There are two different grip screw head profiles and grips that match them.

If you use the countersunk screws on grips made for flat-head screws, you will crack them, and it is not easy to find replacements.

There were some other minor changes over the years, but these were the big ones.

I have been a big fan of these pistols over the years, and have owned and resealed more of these than I have of the Smith & Wesson 78/79G series. In my opinion, the adjustable triggers of the Crosman guns are better than the adjustable triggers of the S&W guns. The engineer that designed these air pistols later had a hand in the design of the Smith & Wesson guns.

I got this one cheap

I saw this pistol online with a $50 or best offer price tag, and no photo. These two things together usually tell me to run away and let someone else take the chance.

I got to thinking I could always use it for parts, so I took the bait and contacted the seller. I found out he lived not too far away, and decided on a face-to-face look at the pistol.

He sent some fuzzy photos by text, that didn’t help my feelings about the deal.

In the ad he said the gun had leaks. When I finally saw it, it was one of the roughest Mark Is I have ever seen. It had been repainted several times, and at some point, someone had covered the bare spots with a permanent marker to make it all black again.

Mark I right
Right side.

Mark I left
Left side.

I put a CO2 cartridge in it and it vented all of the gas out of the piercing cap while I shot it a few times. [Editor’s note: Doing this in front of the seller is a big negotiating tip, because it emphasizes the fact that his gun doesn’t work!]

From this short examination I knew 3 things:

1. This was an early model Crosman Mark I in good mechanical condition.

2. All of the parts were there.

3. It did NOT leak out of the barrel, when it vented the gas.

It’s mine!

I made a ridiculously low offer, and he accepted. When I got it back home and on the bench, I started by cleaning off the permanent marker with alcohol.

I knew it was an older model, but did not realize how old, as in serial number 000659! There is not even a date code.

Mark I serial number
This is an early Mark I.

I now own one of the first ones made and also one of the last ones made.

Bringing it back to life

I put a second CO2 cartridge in it to check it out on the bench. It vented the gas in about 30 seconds and it all came from the piercing cap. That told me the valve seal was still good.

I shot it over the chrono as it was venting. The gun was cold from the CO2 cool-down, but it still registered 485 f.p.s.

Most times the leak is because the tiny o-ring in the piercing cap deteriorates. The piercing pin moves up and down in the older models by a lever. You flip the lever one way to pierce the CO2 cartridge, then return to its normal position to let the CO2 into the gun.

Some online disassembly guides say you have to remove the snap ring at the bottom of the cap and then drive out a roll pin. That is the hard way. The easy way is to use a 3/8-inch wide (9.5mm) screwdriver blade in the slot inside the piercing cap. Use it to unscrew the cover that contains the 006-sized o-ring.

This cover is threaded and acts as a screw to hold the small o-ring in place. It looks in the photo like the piercing pin will prevent unscrewing it, but the end of the pin is actually below the screw slots. Remove this cover. In a moment I will describe and show a newer style end cap that has some different parts and comes apart differently.

With the cover off, use a dental pick to remove the old o-ring. It is probably hardened and will break into fragments when you pick at it. It may not even look like an o-ring, but it is tight around the base of the piercing pin.

Once all the small pieces are out of the cap and the o-ring groove is clean, lightly lubricate the new o-ring with your choice of lube, center the new o-ring over the piercing pin, and push it into its recess. Then screw the cover back into place over the o-ring.

Mark I cap 1
The screwdriver fits into the slots on either side and unscrews the cover. The tip of the piercing pin is below the slots. The cap looks brassy in this photo but it is really steel.

Mark I cap 2
This picture with a different angle shows how the o-ring sits at the base of the piercing pin. read more

    Today I have an early holiday gift for you. No, it’s not an airgun. This gift is much more valuable than just an airgun, and you can use it for the rest of your life. Today I am going to tell you how to decide on something and always be happy with your decision.

    Impossible dream

    I get emails from my own website, www.godfatherofairguns.com all the time asking questions that belong on this blog, but seldom ever make it here. I think the main reason they don’t is the person asking the question knows the answer and doesn’t want all of you telling him what he already knows. And this is one-hundred percent a guy thing. Women do ask me questions from time to time, but they always seem to accept the answer I give.

    Here is an email message I received past week.

    “Need a little expert, unbiased advice, if you would be so kind. I have a few airguns, but I’m thinking I need another. Looking for something to punch paper and probably hunt with, my criteria is as follows.. #1 accuracy #2 decent power #3 quiet as possible #4 something I won’t have to tune or mod. Prefer gas piston in either a break barrel or under lever, oh, did I mention I’d like all this in the $200.00 range? Too much stuff out there and reviews seem to be all over the place, any input from you would be greatly appreciated. Thank you sir.” read more
