"PLEASE READ DESCRIPTION BEFORE ORDERING, TO AVOID ANY WRONG PURCHASES'' 

Up for your consideration is one set of NEW Swivel Posts for all the following Mossberg Pump Shotguns, 500, 600, 590, 835, 88, ect.. Consisting of 2 front posts, 1 rear post, and 3 white spacers, or 3 black spacers, YOUR CHOICE, just ask in a MESSAGE TO THE SELLER! This set is for guns with a second barrel. PLEASE NOTE, IF your gun has the stud hole in the end cap screw, request the 1/4'' LONG POST. These are 100% AMERICAN MADE, by GROVTEC " NOT CHINESE IMPORTS as UNCLE MIKE'S products are " !

As depicted in the second picture side A shows the SHORTER 1/8" threaded post, & both White, & Black spacers. IF YOUR CHOICE IS  SIDE A, THEN REQUEST 113-A WITH WHITE ,OR BLACK SPACERS. Side B shows the LONGER 1/4" threaded post, & both White, & Black spacers. IF YOUR CHOICE IS SIDE B, THEN REQUEST 113-B WITH WHITE, OR BLACK SPACERS.

It is recommended that some form of thread lock, like RED, or GREEN, "LOCKTITE" be used when installing the front swivel post, so as to insure against disengagement of the sling strap while being carried, or shouldered.

This sling swivel setup is a part of the new, and used inventory that was leftover when we closed our gun shop in 2010, after over 30 years   in business as a gun shop, and licensed gunsmith. We opened in 1979, and in 1981 we purchased most of the parts inventory from another gun shop that had opened in 1955, and was calling i quits. In the years that followed, we purchased the parts inventory of four other gun shops that were in the process of closing, or had already closed their business. 

As previous stated, BLACK spacers are also available, just request them in place of the white ones, when you place your order.

PLEASE NOTE: THIS ITEM IS SHIPPED USPS FIRST CLASS PACKAGE ONLY, WHICH IS ALREADY FACTORED INTO THE PRICE, WE USUALLY SHIP WITHIN ONE HOUR OF RECEIVING YOUR ORDER, SO M,AKE SURE YOUR ADDRESS IS CORRECT BEFORE YOU PLACE YOUR ORDER !

Thanks for looking.
