870 magazine “dimple” remover

[ER_STL]

=======================================

I guess I was not clear.

I am NOT using the socket/ smooth bar as a swage. I am using the rod as an dolly/anvil.

I used something about 1/8" smaller in diameter than inside mag tube diameter. Rod must be smooth and small enough to get past the detents.

Rod serves as an anvil inside the tube. Tap the outside of tube on detent until it is smooth inside and out.

Use a smooth face hammer and go with a bunch of light strikes. Repeat for each detent.

Feel with finger for smoothness. Check for smooth follower travel.

I have not had to polish or file the tube inside or outside.


I am running Vang Comp metal magazine followers with no issues.

It was clear to me and it sounds like a good approach; I appreciated your feedback. If I were to do this a bunch of times I'd probably consider it.

I am glad what you did worked well for you.

When I started with dimple reduction, I thought if hammer and dolly did not work I could always drill. It fortunately worked.
