CROSMAN PFM16 SILENCER

I’ve completed the design and testing of my latest Silencer for the Crosman PFM16. The Crosman PFM16 is a full metal CO2 powered Semi-Auto BB Pistol. It has a nice heft to it and a compact and sleek design. I tried to keep the design similarly compact and sleek with matching aesthetics.

3D Model Snapshot

Given that this silencer is so much more compact than our others I’m amazed at how affective it is. I’ve used a 60 degree cone-shaped 7 baffle design like in our Crosman 13XX, Daisy 415, and Daisy 426 silencers, but in a much smaller package. Even with the more compact design it is equally, if not more, affective than our others.

I’ve also uploaded a little video to YouTube with installation details and a firing test. I use a pellet trap and iPhone for the video which isn’t super helpful for really hearing the sound difference. You can check out the reviews for the Daisy Powerline 415 Silencer to see what others have to say about our silencer design.

Crosman 2240 Suppressor

Crosman 2240 Suppressor

Just a quick update on my latest projects. I’ve wrapped up the Daisy Red Ryder scope mount design and have moved on to the Crosman 2240. I have received a few requests to make a Suppressor for the Crosman DPMS SBR Full-Auto. I finally got one and will be working on that soon. I’m also taking a look at the Crosman PFM16 and Umarex SA10.


The 2240 Suppressor is very simple. It requires you to remove the stock front sight by just tapping it off with a hammer and piece of wood. Then you just press the suppressor on by hand with the front sight aligned. The only unique feature is the integrated front sight post. It is very similar to the 1322 Silencer on the inside in that it is round and has cone-shaped baffles.

The 2240 barrel has a flat ground on it that I used as an alignment feature for the front sight. I’m currently testing the Suppressor with various front sight post heights. I’m thinking that I might make it a bit on the high side. That way, it’ll cover close range shooting(if that’s your thing), but it could also be sanded down for longer range shooting. A benefit of the common ABS plastic blend used in 3D printing is that it dissolves in acetone. You can sand down the front sight post and use a paintbrush to coat the abraded surface with acetone to give it a smooth finish.

The Crosman Scope Mounts have really proven to be a hit. I didn’t imagine that they would be so popular. I’m grateful for all the feedback. The mounts are self-aligning on the 13XX and on the 2240. Check out the Crosman 2240 with the Suppressor, Scope Mounts, and Hawkeye Reflex Sight mounted below:

It may not look like it, but the cap and CO2 cartridge can be removed without removing the suppressor. Once the weather clears up outside here in Houston, TX I’ll shoot a little test video. Expect these to be offered up at a great price soon!

Thanks for readin’ ya’ll!

Daisy Powerline 408 Silencer Design

Daisy Powerline 408 Silencer with Dovetail Scope Mount

Daisy Powerline 408 Silencer Design


I received a request a while back to make a Silencer for the Daisy Powerline 408. I went out and bought one to have a look and see what I can do. I messed with it here and there for a while and finally came up with something I feel good about. I replaced the whole stock plastic part covering the barrel with a 3d printed one with a built-in suppressor and optics mount. I also was able to keep the front sight post if you prefer to shoot with open sights.

I started out by measuring and modelling the stock shroud. As you can see in the picture below there was a lot of features to get right. I lucked up and didn’t have to spend a lot of time optimizing it for 3d printing. I printed the shroud and installed all the guts without issue. Next, I added a printable silencer to the end and tested it out. If you’d like to check that out you can see it on YouTube HERE or look at my previous blog post.

I really like the 408. It’s nice to shoot pellets with a rifled barrel and CO2. Considering the decent accuracy you can get I though it might be nice to add an optics mount as well. My first few attempts were not great. The optics would clamp on the sharp edge of the dovetail rather than the grooves under the sharp edges. It would clamp really well, but deform the sharp plastic edges. Also, it was a challenge to make it look sleek and like it belonged on the gun. I eventually found a way to make the 3d printed dovetail functional and look like it belongs there. See below:

Finally, I added some of the little cosmetic details to tie it all together and printed the final prototype.

Final prototype 3d printed with ABS plastic.

These things take a long time to print(8hrs/piece) on an FDM printer at .2mm layers and would be pretty costly for a 3d printed part. I most likely will have them printed in PA12 Nylon by an American company given that the cost is comparable if done in bulk. Nylon is extremely tough and the SLS(Selective Laser Sintering) process leaves a very smooth finish. Here’s a little preview of a prototype that I’ve had printed in Nylon using SLS. When I finally put these up for sale they will have a similar finish.

Hopefully I’ll have them ready for early to mid-November. Thanks for reading!

I’ve made a new silencer for the Crosman 1322/1377. Here’s a mesmerizing time lapse of the 3D printing process.

I also just put up a little video of the installation process and testing on YouTube. Check it out here:

Making the Daisy Powerline 426 Silencer

I’ve had a few requests for a silencer for the Daisy Powerline 426. It’s been a lot of work, but I’ve finally got something that will work without making alterations to the gun itself.

The biggest challenge to overcome is that it needed to somehow mount on the gun without damaging it. The Powerline 415 Silencer presses into the plastic barrel shroud, but there is too little space to do that in the 426. My first idea was to make little nubs that clutch the outside of the shroud. See below.

The first attempt at a gripping adapter

The adpater DID grip the gun, but it wasn’t secure enough. The next idea was to use the under barrel accessory rail along with the gripping nubs.

The first try at a 426 Silencer

The silencer worked and looked really cool and sleek, but I knew a lot of people would be disappointed that they couldn’t mount a laser as well. The next idea was to use the under-barrel accessory rail, and use the silencer as a base for a laser instead.

Daisy Powerline 415 Silencer Test

This is just a short video showing the sound difference without and with the 3D printed silencer on the Daisy Powerline 415 CO2 Pistol. I’m shooting Daisy Precision Max Steel BBs. This video really doesn’t do it justice, but you can certainly hear the difference. I shot at an archery target to take down some of the secondary noises.

Daisy Powerline 415 Silencer Build

Daisy Powerline 415 Silencer Build Part 1

3d Printed Silencer Inspired by the SilencerCo Osprey

My son just bought his first CO2 BB Pistol. I started him out with the Daisy Powerline 415 for ease of use… and low cost of course. He’s 10 and scrawny like me so I wanted to make sure it was easy for him to load and shoot. He read the manual(because I made him) and we set it up. It was getting dark outside, but I wasn’t going to let him go to bed without at least firing a couple of rounds. He fired the pistol and the sound really reverberated and got the neighborhood dogs barking. So my mind went straight to engineering mode, “we gotta make a silencer for this little thing.” So that’s what we did and it works great. I need to get my hands on a decibel meter, or perhaps get someone who has one to test it(anyone, heh? heh?) but until then you’ll have to just listen to the test video in Part 2.

Side Note: Is that trigger pull long, or what?! I always emphasize the importance of not yanking on the trigger, but it really takes some getting used to have such a long pull. He kept thinking that the gun wasn’t working right. Slowly pulling and pulling and pulling… “Dad, is the safety on?”


The Outsides

As you can see, in the above pictures, the design was inspired by the SilencerCO Osprey. I like that they match the profile of the pistol, so I went with the same look on the outside. I did a little research on the baffles of different silencers and decided to go with the cone type, rather than what is inside the osprey only because that seems to be tried and true and works well for 3D printing.

The Insides

In the picture below you can see the inside of the Osprey. That’s purrrdy.

SilencerCO’s Osprey Cutaway

In the picture below you can see my crappy cutaway. I chose 60 degree cone-like baffles, so they could print without any support. This would be impossible to injection mold in one piece.

My Really Junky Cutaway Sample(I blame the bandsaw)

To mount the silencer you just slide it in and it snaps in snuggly. I fired about 100 rounds without issue. It REALLY cuts down on the noise and doesn’t affect the accuracy a bit. By accuracy, I mean the standard random 4-5″ 10 yard grouping. My son loves the way it looks and I’m happy he can shoot in our backyard without concerning our neighbors now. I’ll probably add to the aesthetics a bit later and post the files to 3D print it. In part 2 I’ll post a video of the shooting test so you can hear the sound difference, so stay tuned.

3D Printing Airgun Targets

A Great Way to Get Kids Excited About Shooting

I came home from work today and saw my son out back shooting away with his Red Ryder.

Usually the only time he shoots is when I invite him and his sister out to do some backyard plinking with dad. I went outside to let him know I was home and to talk with him. I wanted to hear what got him excited about shooting. He had so much to say… but it mostly came down to his new targets.

We’ve been experimenting with 3D printed targets. Little men, tombstones, robots, solid, hollow, thick, thin, small, big, shattering, bb catching, etc. But we finally found the one that was the best.

The little black plastic figures are modeled and 3D printed… by him. The wooden blocks with the block man on it was also made by him.

He set them up and tried to have them arranged in such a way that there were some who were enemies and others who were friendlies. Think Time Crisis arcade shooting. He’s got a good imagination, but it’s not too far from that and just as much fun.

He invited me to try shooting one of the 3D men behind a wall without knocking the wall down. I drew up and shot him without touching the wall and handed the Daisy back to him(I got lucky). His jaw dropped as if I just revealed my superpower.

I told him to keep it up and went inside. He didn’t come in until the mosquitoes got the best of him.

He had a blast. Every time he knocked one down or spun one around he was excited to go pick it up and see where it hit and what kind of damage it did.

We found that it is best to make them hollow with only about 20% infill. This way the men don’t shatter after one shot. They get damaged by every shot(the fun part), but not so much that you can’t keep shooting them again and again. All in all a successful little experiment. I’m sure this will end up being a regular thing. It has certainly served to get my kids even more excited about shooting their BB guns.

I may start adding them as a sort of bonus item thrown in with The Little Buck Rail scope mount. I’ll wait until we’ve thoroughly “tested” them though;) Have an idea for getting the kids shooting? What has worked for you?
