The following listing includes the most commonly requested parts for the most commonly owned Mossberg modern-era shotguns.  This includes the current pump action 500®, 590® and 835® Unti-Mag® as well as the discontinued 5500®, 5500MKII® and 9200® semi-autos.  We carry many more parts for each of these models than we would have room to list here. On the flip side, while we try to be sure that every item for every model listed below is currently in stock, we may sometimes be out of stock on items from time to time. Calling us at 636-937-6401 is the best way to assure that we have what you are looking for. You may also inquire by e-mail to vic@havlinsales.com. Please note that while models may be grouped here for pricing similarity and space, each model is distinctly unique and we must have the exact model number and caliber in order to fill your request, i.e., 5500® and  9200® are very different models though they may have similarly-named parts. Also note that some items may be on "special" during certain seasons of the year. 

PLEASE NOTE that in our travels when buying out gun shops and other stores, we run across items that are technically new but are scratched or have blemished finishes.  This is particularly true of stocks, barrels, chokes, etc, with "showroom wear."  We always indicate these as seconds, blems or "as new" condition items.  Be sure to check the WEB SPECIALS page to enjoy additional savings. Also note the CLOSE-OUT BARRELS page, and two new sections we have added:
