Factory replacement .177 caliber barrel for the Shanghai Airgun Factory/Industry Brand QB78 airguns.

Comes with new o-rings and bolt.

Can be used to replace a damaged barrel or change caliber of your rifle.

Note: This barrel is a direct replacement for the QB78 and has a 14mm diameter. It will not fit the factory sights on a QB79, but can be used on one.

This barrel is not a direct replacement for the QB78D (Deluxe) or AR207x barrel (AR barrels have notches for the sights/brake and both QB78D and AR207x barrels are 15mm in diameter). It can be used on these rifles if the barrel band is shimmed and you do not wish to retain the factory open sights.
