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!

DAISY POWERLINE 408 SILENCER INSTALLATION AND TEST

In this video I show some quick details about the Daisy Powerline 408 Silencer, how it is installed, and do a firing test. It’s fairly brief and to the point. This is only a prototype and not what the final product will look like. Just a sort of progress report I guess… Thanks for watchin’

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.
