I work at a gun store in a small town. Rough looking fella came into the shop at asked if we had any batteries for this flashlight of his. We told him we didnt and he asked if we'd buy it off of him.

I was curious so I asked him what hed take for it and he instantly shot out an offer of $40.

Not the biggest gun gear nerd, but I knew it had to have been worth more than that, and I have been looking for a weapon light to go on my 3rd gen Glock 21SF for a while now.

So I paid him $40. Had to wait until the end of the day to pop over to the hardware store and buy a pack of batteries. Sure enough it worked, and man, even though its an older model its really bright.

Super stoked about this.

I collect guns but mostly focus on more vintage target/hunting guns, muzzle loaders, and revolvers.

This big boy came into the gun shop I work at and the price was too good to pass up. 21 Gen 3.

I'm actually pretty stoked about this one.

In the 1955 MGM cartoon Cellbound, spike the prisoner dog escapee digs a tunnel to freedom from his prison cell using only a spoon.

As he dumps his last spoonful of dirt outside his prison cell and and completes his tunnel, he says "six trillion, five hundred billion, four million, three hundred and eighty five thousand, six hundred and thirty two". (6,500,004,385,632).

He jumps into the mouth of the tunnel and scurries down its length until he meets the end and exclaims, "Daylight! Freedom after twenty years!".

1.) Given that he uses what appears to be a table spoon to dig his tunnel, how long would the tunnel approximately be given the number of scoops he had to dig out to make it, with the tunnels diameter being large enough to fit his body?

2.) How big would the pile of dirt outside his sell window be using his number of scoops?

3.) This may be a difficult question to answer, but would it be possible to dig a tunnel via 6,500,004,385,632 scoops in as little as twenty years? Or would it take longer to achieve that many scoops?

Okay guys, I have a bit of a head scratcher here. I recently picked up a used Ruger Mark II Target, .22lr pistol and it’s a fantastic, lovely pistol to shoot. But I am having an odd problem with light strikes.

The problem usually manifests as follows. With different kinds of ammo, and different magazines, I will insert the mag, and start shooting, only to have a failure to fire. It occurs with multiple different rounds in the magazine. Sometimes the first, sometimes the 3rd, 4th, 5th, 6th etc. I will eject the magazine, and attempt to manually retract the bolt, only to have the extractor fail to remove the cartridge from the chamber. (I have cleaned the extractor recess)

Usually it will fire after I let the bolt go back into battery so I know they’re not completely duds.

Initially I thought I might have a worn firing pin. I changed the firing pin to a Volquartsen Surestrike firing pin and that did not solve the issue. I then came up with the idea that perhaps what was happening was that when I pulled the trigger, the firing pin was striking the case rim and pushing it over the extractor claw, wasting the firing pins energy and then producing the failure to extract problem. But the more I think about it, the more I realize that that is likely not what’s happening since the extractor claw is pushed away from the cartridge case inside its recess in the chamber face when the gun is in battery. I ordered a new Volquartsen Exact Edge extractor but I’m not confident that will fix the issue.

Now I’m left with what to do as my next step. Volquartsen makes their “Target Hammer” which has holes in it, I’m guessing increase the hammers velocity? I could also get one of their mainspring housing. I noticed when I’d disassembled the gun that there were some burs on the hammer strut and I don’t know if those could be catching on the mainspring housing when the bolt is coming rearward.

It absolutely refused to work with Aguila ammo and seems to prefer high velocity ammo. I don’t know if that’s because of the more exacting case rim measurements.. or if this is a bolt velocity/recoil assembly induced issue.

I’m really at my wits end here. I can’t draw any useful conclusions from these symptoms that point me in a sure direction. It’s weird that it likes some ammo more than others. If I was having a problem with the strenth of the firing pin strike, I don’t think it would be different between different types of ammo. I’ve detail stripped the entire gun (except the extractor, I just lubricated that) and have also cleaned the chamber very well.

At this point I’m considering getting a whole new bolt, hammer, hammer bushing, mainspring housing, and also a new recoil spring just to rule that out.

I’m sorry for the very lengthy post but this seems like a multi-faceted issue and I think the nuances are important to try and diagnose the problem.

Gorgeous watch, I must know what it is :)

Thanks a bunch guys.

Thanks for any help you guys can provide.

Hi everybody, I'm here to consult the hivemind about a problem I'm having with my poverty pony budget blaster.

I just switched over from the M4 style adjustable stock with carbine spring and 3oz buffer to a A2 rifle length stock (which looks awesome btw).

I weighed the buffer and it is a 5.2oz rifle length buffer and what I *assume* is a regular power rifle buffer spring.

I went to the range to test it out after work and had two stovepipes in the first 20 rounds. Now I am left wondering what the next step is. My research on AR buffer systems has led me in many directions and to all sorts of different opinions on what the appropriate buffer weight for a certain barrel/gas system length should be. Some are saying it has less to do with the gas system length and more to do with the stock length.

My intuition tells me that my rifle stovepiping after going to a 5.2oz buffer after the rifle worked fine with a 3oz buffer is to go back to a lighter buffer, so I figured id order something like a 3.8oz rifle length buffer (I was already considering using a H1 buffer with the original carbine length stock).

I know that with a rifle length stock, the buffer and spring will be physically longer, but i am still wondering what weight I need to go back to. The rifle was reliable with the carbine length spring and 3oz buffer, so I know the BCG/mags/FCG are good to go. It has never stovepiped before, so I'm sure it has something to do with the heavier rifle buffer.

But now I'm being told in a different group that my rifle has too much bolt velocity and that's what's causing the stovepipes. I'm at a loss as to what my next step will be to solve this. Sorry for the long explanation and thank you for any help you guys can provide.
