I discovered this shiny muzzle brake in a field of stuff on the market on the Toys that Shoot airgun present final yr. I had no actual plan for it on the time, but it surely was solely $10.
I did just like the undercut on the underside, and I believed the machining was fairly clear for the value.
Absolutely, I had one thing that this 14mm diameter would match. See the justifying? Introduced it dwelling and put it in a bigger field of stuff with different shiny issues the place it sat ready.
A few of my airgun initiatives by no means appear to be completed. My outdated CP1-M pistol from the now defunct M-Rod Air is an efficient instance. It is worn iron sights, purple dots, modified grips, triggers, barrel shrouds. A distinct configuration each few months. Altering wants and views, altering pursuits, too many options–all looking for capturing perfection. No less than that is the hope we’ve got at any time when we strive a brand new airgun accent. Possibly I am simply drawn to shiny issues like a magpie.
Anyway, I used to be by no means actually completely happy after sleeving the barrel in carbon fiber barrel. It was supposed to simply be a stopgap till one thing extra acceptable got here alongside. One thing extra air pistoley.
The opposite night time, my mind made the connection:
Muzzle brake
+ CP1-M
= Superb
All of the brake wanted was only a easy shim. There was a cut-off scrap of black acetal already on the workbench.
Fast and straightforward. Went to the lathe and confronted the top.
Took the diameter right down to 0.550″–just barely smaller than the bore within the muzzle brake.
I actually wish to machine acetal. Simple to chop and no razor sharp chips all around the ground.
Check match.
Actually cosy. It is really a light-weight press match.
Minimize it off and chamfered what would be the entrance finish of the shim.
I wish to drill for the barrel with it put in within the physique of the brake.
Pressed the acetal plug in, snugged the set screw then progressively by means of drilled for the muzzle diameter.
The muzzle of the CP1-M barrel is stepped down. A 25/64″ drill bit is an efficient match.
The insert is about 7/8″ into the bore.
A couple of higher pics of the brake.
A pair pics of the stepped barrel on the CP1-M.
Used an o-ring to shut the hole on the rear of the brake.
Pushed up cosy. A fast visible bandaid to cover an unpleasant hole.
Carried out?
Whoops! Virtually forgot. All the time wish to ensure there is not any pellet contact with a newly put in muzzle brake.
Some electrical tape
Over the muzzle.
And a check shot. Seems OK!
Extra in a pair days.
