12 gauge Remington Ventilator. Shot maybe 4-5 times over the years. I believe it's .655 inside diameter. Like new condition. $45. TYD
That's a beaute! Don't see these every day guys, excellent choke, was way ahead of its time
I have three of them. My son shoots one, I shoot one, and the other is my youngest sons and he doesn't turkey hunt much any more. My 3 inch 21 inch barrel 870 loves this choke. My go to choke with lead and you don't see them for sale very often. Saw one not too long ago that sold for 60.00. Well worth the asking price on this one.
I'll never understand why Remington stopped making this choke. Too many arms/ammo manufacturers will stumble up on a good design for a product, and it will work significantly better than previous examples. At that point, the manufacturer will promptly begin production of a newer design and stop production of the good one that is working fine, like this choke.
My limited patterning with it before Win Lonbeard came out (just plain lead Win 12 ga, 3"), produced VERY even groups up to low 100s with lead #6.
