Mossberg® Modern Shotgun Parts
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® Ulti-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. You may 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.
Depending on the item, fitting may be
required by a qualified gunsmith to insure proper function and safety.

Comparison of action slide lengths: top 7-5/8”, bottom 6-1/2” Measure from
top of threads to bottom of collar that holds the action bars. This measurement
is critical to fit when ordering forearms or stock sets that include a forearm.
For the most part, 20-year and older sporting shotguns and new tactical shotguns
use the 7-5/8” slide. New sporting models have used the 6-1/2” slide for almost
20 years. There are exceptions, however. To be sure, measure!
NOTE: Since 2006, most new 500®, 535® and 835® sporting shotguns
with synthetic forearms may not use an action slide tube at all; rather, the
pump handle will have two integral bars pinned into the handle itself. If you
have one of these, you cannot use a forearm that was designed to go over an
action slide tube without first buying the correct length tube and action slide
tube nut.
Old Style Stocks and Forearms for K850XXX serial number or older – action
slide length 7-5/8”
Stocks and forearms for 500® 12 ga will also fit 835® Ulti-Mag® 12 ga. Measure
the cylinder potion of your action slide to determine if old style
(7-5/8”) or new style (6-1/2”)
