for 20bucks its a good choke.. i use the truglo which patterns very well out to 25 yards but then it widens up. I like it though since under 20 yards its not a pattern the size of a slug. Keep in mind that if something patterns tight out to 40 yards, then you better be dead on at 10-20yards if not then you will miss

but again, for 20bucks its a good bargain!
