found an older Simmons trap barrel that had been ported (seen others with same porting design) However when you look down the barrel it looks like they never cleaned up the burrs from drilling the ports. Thought it was just gunk build up but brass brush on drill made no difference. Pushed a small aluminum rod down to try and scrape off, that only marked up the rod. Any ideas how to remove these burrs, don't know if they would effect pattern

The best DIY I can think of would be a brake cylinder hone, but I'm not sure how that would affect the barrel ID otherwise as it took down the burrs. You'd almost need a piloted reamer the exact ID of the bore to knock down just the burrs.

If you google deburring tool. It is what machinist use, you can make one small enough from a straightened spring and dremel.

thanks for the suggestions.didn't want to risk changing inside of barrel, wonder if a brass rod turned to dimensions of inside of bore and pushed through a few times would work

With 400 grit or emery cloth, it would take a long long time to remove metal from your choke. Don't overthink this., the burring is probably quite a distance before the choke.

I use a flex hone, if the burrs are big, a 3/8 " round 6 inch long stone, a few stroke to knock the burr down then the flex hone. be careful of a brake hone, it will remove metal ! as for the deburring tool no no no

used wooden dowel and with emery wrapped it was a loose fit. Was able to look thru ports to see where emery started and just bared down on the area of the burrs. Didn't smooth them right down, but way better than before. Thanks for the tips

Looks like the perfect tool. Do you know who might sell them?
The tool you need is a Noga RC1000 reversible deburring tool. It depends on how big the ports are as to whether or not it will work. The holes need to be a minimum diameter of 0.120” for it to work. This is the smaller one. It’s hole deburring range is 0.120”-0.220”.

...and the larger Noga RC2000 which ranges from 0.200” to 0.390”.
