All gauges feature fibre optic bead, gloss oil finish, checkered walnut, engraved low-profile steel receiver, mechanical trigger. (also features ported barrels and Invector-DS choke tubes.)...

This is it. The baseline standard for an industry that craves top performance.  The new Citori 725 is the evolution of John M. Browning’s legendary B25 Superposed, now with the modern performance advantage of a Low-Profile receiver. The new 725 receiver is significantly lower than other Citori 12 gauge receivers, yet the 725 shares the renowned durability of generations of Citori over and unders with the same rugged full-width hinge pin and tapered locking bolt design.

Balance, form and a large dose of excellence. With a 725, you get the "one with the gun" feeling you want, with the long lasting durability you expect from a Browning over and under. And the features don't stop there. The 725 showcases an all-new Mechanical Trigger (FireLite) that offers unmatched feel and lighter pull weights than ever before. Inflex Technology has also been added to make shooting more comfortable. Experience the benefits these improvements can do for your shooting with a new Citori 725.

A few differences. Every Citori 725, no matter the gauge, has a full compliment of performance features. But there are some differences between gauges:

12 and 20 gauge versions use the Invector-DS choke system and barrels are ported.
