The Rosco Barrel Swivels are standard barrel swivels that have a variety of uses. The superior quality and strength of Rosco swivels are the reason why they have been considered the industry standard since 1926. Made in the USA from the highest quality brass, ROSCO swivels have been winning fishing tournaments and bringing home dinner for generations and truly have been making fish stories come true. We carry the nickel and black colors of the standard Rosco Barrel Swivels in many sizes ranging from the largest size 4/0 to the smallest size 12. Quantity varies, see below.
