Improved cylinder barrel on 870 tactical

[kahuna_99]

My issue is: i can't seem to find an improved cylinder barrel that fits my 870 tactical with the +2 magazine extension that comes standard on the shotgun. Is there a way around this or should I buy a shotgun with the improved cylinder barrel factory installed?

Does your 870 have a standard 4-round base mag tube and a separate magazine extension, or the long single-piece 6-round mag tube?

If it's the former, any 12ga 870 Police barrel should drop onto your gun. Fixed-choke Express Tactical barrels are usually just Cylinder bore, but the Police barrels can be had with fixed IC or Modified chokes.
