For some reason exact dating is for law enforcement, only for crime trace, but a 500AB with a D serialization is 1971-1972.By 1973, they were into the G with 6 digit numbers and had dropped the second B as all shotguns now had the twin or double bars.My favorite fore-end grip for a 500 (or an 870) is the Hogue OM. Your 500 looks like it has the longer action tube assembly (there are two different sizes, with the shorter being more recent production).I just got this from Cheryl Havlin,the Mossberg folks in Missouri.The Shockwave Raptor Lug enables you to reduce your PGO firearm’s barrel length to 14″—at a fraction of the OEM kit’s price. The Shockwave Technologies Raptor Grip gives you a great, felt-recoil-reducing grip on your firearm. Raptor Strap kit for the Mossberg 500 and 590 series keeps your forward hand in place during recoil. The OPSol Mini-Clip lets you practice with less-expensive, lower-recoil 1.75″ birdshot, buckshot, and slug shells in your 12-gauge Mossberg 500, 590, 590A1, or Maverick 88. This file contains additional information, probably added from the digital camera or scanner used to create or digitize it. 12 or 20 interchangeable barrels , 2 3/4 or 3 inch chamber , gas operated semi auto , various chokes with multi choke standard , except on slug barrel with rifle sights . blue or camo finish , checkered walnut or camo stock , top of receiver safety .
Youth Patriot models with variable length of pull and 20” barrels are also available.
Anyone have any recommendations for a new forend and pistol grip?
Im really just looking for something that is going to fit really tight for the mossberg 500ab.
The Havlin's are fantastic, and as soon as I get some extra cash I will join the Mossberg group.
All Mossberg 500AB parts are interchangeable with the 500A.
