Stumbled across this thread and had to join the group to pass along this info. I've had my model 11 Sportsman 20 ga for about, wow...30 years now! First firearm I ever purchased and one that I will never sell. I started hunting around for some spare parts and found Art's Gun Shop online. He specializes in Browning's but has rebuild kits for the Remington Model 11 as well. A little pricey but the only kit of this type that I'm aware of. They make both 3 and 5 shot kits for the model 11 20 ga. Hope this info helps and doesn't violate any guidelines.
