Fits most of the Theoben break-barrel rifles.

The breech seal is the one that goes in the end of the barrel. Worn breech seals result in loss of compression resulting in inaccuracy and loss of power.

Please note: Original part is not available (as Theoben no longer trade).

This is a replacement aftermarket part that differs slightly from the original.

Compatible with many models; Fenman, Evolution, Crusader, Countryman, Sirocco, Classic etc…

Most rifles take this breech seal – However we have reports that some rifles had different size seal. Please check that the outside diameter for this seal on your rifle is 13mm or just slightly less.
