i have an 870 supermag that has had a remington ventilator choke stuck for probably 15 years. pretty much gave up on it because i didn't want to damage the barrel. its a no-wrench style. i have not found anything substantial enough to put through the port holes to twist for leverage and did not want to take the channel locks to it so i kind of gave up. any thoughts on removal at this point? the gun has the camo paint so not sure how it will hold up to heating.
