Well after sitting idle for four years (billet parts)

So butt plug aside my son has been taking a fusion 360 class in the afternoons.. today I told him to draw the the spacer we need to go between his silencer and his ar15..

So here is the problem the silencer screws down on the barrel and has nothing to butt against.. so it just runs to the end of the threads on the silencer.

Here is the issue..

And here is the solution! Pretty proud of him to be able to take a class and even though it’s a simple part draw it himself..

I have no idea how to use cad but will start learning early next week. I was a manual machinist that worked off of paper drawings.. I’m that old

Are the relief cuts in the silencer there to allow airflow? You may be blocking that. I know less than zero on nugs and only slept on the floor of a dirty rv last night. so i have no clue if thats an issue.

The reliefs are there so you can use a spanner wrench to tighten it on the gun, or disassemble the silencer itself.. it’s kind of a weird design actually.
 
I need a surface grinder bad!

Found a few old ass six-twelve deluxe units in Pomona, but they still want $2500+ for them. Was hoping to find something $1500 or less.

Was going to call you one day when I needed to surface down a pinion depth spacer for an Albins, but figured you might be annoyed since it was 10:30 at night. LOL
