Briley X2 Extended 20 Gauge Mobilchoke Modified Choke Tube

A popular and effective way to improve the performance of your shotgun. Choke tube constriction takes place over a longer length than in standard tubes, reducing shot deformation and improving pattern density. Tubes extend 3/4" to 1" past the muzzle, depending on the brand of shotgun. The extended portion is knurled which allows quick changes without a tube wrench and is also clearly marked for choke identification.
