Notos Slip-on Moderator Extension

This is an extension for the stock Umarex Notos moderator that does not require removing the stock baffles. I wanted to make something that would allow the Notos to be backyard friendly and very quiet but would come off easily when going hunting or when I didn't want so much extra length. For some it will be easier not having to punch out the stock baffle pins and deal with directly modifying the pellet rifle. 

I used 3x 3mm M3 threaded inserts and 3x 6mm M3 grub screws to hold the extension in place. The set screws do not need to be very tight, just snugged up and lined up with the depressions in the stock moderator. The shape of the depressions will prevent the extension from sliding off the front. 

There is an internal stop just slide it on until it hits that and then snug those set screws. 

If you wanted to skip the threaded inserts and just put screws directly into the plastic that should be fine, I have tested that and the moderator extension worked but I thought it looked messy. 

you may have to play very slightly with the scale depending on your printer, I have only tested this on my A1 Mini.
