I ordered this breacher/brake knowing it wouldn't fit my DA 12.5



I didn't want to take it to a machine shop and have them mill it down ($) and I found my step drill at 7/8 was damn near perfect!

I forgot to take a pic but it came out at 0.872 after drilling it.

There is a hole for a set screw in the bottom of the breacher but it wouldn't contact the barrel with the sight post where it was so the hacksaw got some use

Cleaned up

Insertion

Being unfamiliar with silver soldering and not really wanting to weld this thing on I figured set screws and JB weld would probably work so I enlarged the original hole, added 3 more and tapped them.

I drilled in little divots for the set screws to seat into

Test fit. Here you can see the $1.40 worth of set screws

I applied a healthy dose of JB, tightened the set screws down and filed off the excess threads

Black paint makes everything look better.

Added a +1 tube extension which was half the reason I put this thing on


Finished product



I'll go burn a bunch of powder through her and see if it stays on or if it makes any difference in the way it patterns.
