870 12 gauge barrels

The 870 barrels of Express and Wingmaster interchange within gauge. EXCEPT the Special Field models they will only fit Special Field receivers. The differences between Wingmaster and Express barrels are: finish, the WM is blued and the EX is coated. Wingmaster barrels (earlier guns) have a detent ball on barrel ring that locks into a dimpled mag cap. Later Wingmasters and express guns have a notched plastic mag tube insert that ratchets into the inner magazine cap. All barrels will fit standard, magnum and super magnum receivers (except special field) But you can only shoot cartridges in them that the receiver is rated for.
