I love the old Mossbergs. My M152 was the first gun I bought at our local gunshow, and gave me the bug! I like the folding fore end, and found two 15-round magazines (paid more for the maggs than for the rifle!).
Followed it with the M146B with T-bolt handle (rebuilt from a rusted ruin), the 640KD Chuckster (actually the Revelation store brand), the M34 singleshot (ultra-sensitive trigger makes it a looker rather than a shooter), the M42M (currently wearing a Marble-Goss target aperture rear sight and Ruger 10-22 ring and blade front sight), and finally the M320BB singleshot (old Boy Scout trainer - not pictured here).
