Crosman Another money pit. My crosman 3622.

Next, I took it back apart, and mounted the gen1 Mrod trigger group. No modifications or spacer needed, just bolted up and has ZERO sear drag.

Now I moved on to the stock. I have 4 sporter style K98 Sako mauser stocks I got off ebay on an auction. They are semi finished, so plenty of meat to play with. Always loved the lines of those stocks, remind me of the daystate Huntsman stocks with the rollover comb.

I did just a bit of inletting to fit the trigger, and used a 3/4" drum sander to open up the barrel channel so the air tube would drop in. The bolt handle lines up damn near perfect with the mauser stock notch once I inlet the trigger channel just a little more, it will drop right in to the notch.



I had planned to mount my multi shot breech to this action, but im liking the slim look of the rifle right now.

Here she is with the scope back on it.

Only issue I see with this stock, is it will need some bedding done and make the trigger guard/magwell cover. Easy enough I guess, just going to use plate steel and cut it out and weld the guard to it and paint or have it powder coated.

The finish of the stock has some bad water damage that I'm not sure of how to remove. I've heard oxalic acid will lift the stains, but im worried it could eat the wood. I doubt they'll sand out. I could give it more soaking/water stains and then stain it and make it look like salted maple. Dunno.

I would like to keep this a wood finished gun and not have to paint it, so if someone knows how to fix that, let me know.


Also, I know some people will get bent over the fact this is a $120 gun, and it's pointless to mod etc... I welcome that input. I am a tinkerer at heart, so I see opportunity here vs a waste of my time/money.

As another inveterate tinkerer, all I can say is "Looks great." Beyond looks great, it looks tempting.

Thanks! I have 3 more of these stocks, one is already chosen for another build that's based on a mix of crosman and beeman parts.

Use a 50 to 50 solution of white vinegar and water. Wet a cloth and let sit 10 to 15 minutes then lightly scrub in the direction of the grain.

I've heard white vinegar would do it, and also heard mayonnaise lol.

WoodWelder said:

Cleaning vinegar is much stronger......The issues with using other acids are they must be properly neutralized before staining or clear coats. Mineral oils or mayonnaise will leave an unwanted residue.

So do you think this deep stain would come out? I have a gallon of fresh white vinegar I just bought.

WoodWelder said:

Absolutely, make sure the stock is completely dry before sanding.....75 to 80% will be removed by sanding alone.

I'd get most of it out first with the vinegar, let dry for a few weeks then sand it.

Thank you! I guess it goes without saying I should trust your knowledge with a username like that!

Nice little rifle, I have been eyeballing one. Nice to know about the marauder trigger.

You'd have to cobble up a trigger guard to use the factory stock, but nothing is impossible. Will make a world of difference in the trigger for sure.

Well my multi shot breech showed up and I bought an Mrod barrel from a member here. This is the stock 21" 3622 barrel, so I can't use it since no internal breech o-ring, but this gives you the visual of how it'll look with the raised breech.

Now I must make an air stripper and shroud in 3/4" OD to match the air tube. 3D print some baffles, and should have a mouse fart quite, multi shot 18 fpe gun with a great trigger and nice furniture. Oh, it'll also be under 6 lbs scoped too. Has just enough weight in the stock to shoulder nicely.




So let's see how much I'm into this rig.

3622: $120 with discount code
Breech: $105
Stock: $40
Mrod barrel: $50
Mrod trigger: $60

Total so far: $375

Shroud will run me about $35 to make, and probably another $25-$30 or so on sand paper, different hammer spring, and better breech screw.

Yep, another money pit lol. It'll be worth it to me though, I already feel attached to it since I constantly miss my old discovery rifles.

I have a question,

So crosman dropped the Disco then came out with this one ?

Yeah, I don't get it either. You'd think they'd just reissue the disco. It does have a smaller diameter air tube/valve and shorter barrel, but that's about the only real difference.

Don't forget the Maximus -

And as for the 3622, good job so far!

I almost bought one off ebay last week, but they wanted $200+shipping AND it was 177. I don't have any 177s anymore. Sure, I could've swapped calibers, but you can only be in so many rabbit holes at one time!
