Any other aftermarket makers of custom choke tubes for 10 ga shotguns?

I have a lot of Carlson choke that seem to work great, but I have not measured them.
Maybe Briley would correct the situation if you contacted them.

Steel or lead?

Rhino, angle port/ballistic specialties.

wilsonprecion products . custom chokes. ive patterned theres against the briley and some others and they were the best.

I have many Carlsons. They work fine for me.

Try George Trulock/Trulock chokes. Great product great service.Price and Performance are also great.

I just purchased three Wilson Precision chokes for my SBE and can't wait to try them.

Google Mike Orlen.

For waterfowl here in Louisiana I use either a Patternmaster or a Kicks. Several of my hunting buddies like the Kicks but I like the Pattenmasterm best.
