It has a convenient clean-out tube magazine cap, a front bead sight and 'corn cob' strapped forend to keep shooter's lead hand clear of the muzzle. The 590 Shockwave Raptor bird's head pistol grip is uniquely shaped to minimize felt recoil. Classified as fully-compliant by the BATFE, this model requires no Tax Stamp for transfers.
