Choate ‘Night Manager’ Now Available for Mossberg 500 and Maverick 88

Earlier this year, I told you about the “Night Manager” from Choate Machine & Tool. It’s a handy-dandy add-on for tube-fed shotguns, and it extends magazine capacity while adding a sling mount and removable picatinny rail. Some readers lamented that it’s not available for the ever-popular Mossberg 500. Well, lament no more!

Back when I originally published the story, Fred Choate commented on the post to say they were already working on one for the 500. The problem with the 500, you see, is that the under-barrel lug used to attach the barrel to the mag tube only has a small hole in it, so the M500 Night Manager can’t extend the magazine capacity of the 500 — but it can provide a sling mount and indexable picatinny rail mount. They’ve now finalized the design and are shipping the M500 Night Manager.

Here’s some info from their press release:

The Night Manager Accessory Mount for the Mossberg 500 consists of a machined steel barrel nut/threaded adapter and an aluminum shroud. The aluminum shroud attaches to the adapter and is drilled and tapped along the bottom and sides for mounting Picatinny rail sections. Its unique design allows the shroud to rotate to orient the attached Picatinny rails where needed and then uses an AR-15 castle nut to lock it down in the desired location.

By mounting accessories on a tube extension, it allows use of the full length of the shotgun’s forend, which often can be short on law enforcement models. It also prevents accidentally turning lights and lasers on or off while firing the shotgun due to recoil. The Night Manager also includes a sling mounting plate that can be installed to attach the sling on the right, left or bottom of the shotgun.

The Night Manager Accessory Mount for Mossberg shotguns is available for the model 500 and Maverick model 88. Two models are available, one for standard mag tube length guns that use 18.5” barrels, and a longer version for Mossberg 500s with standard magazine tubes and 20” or greater length barrels.

The Night Manager Accessory Mount replaces the barrel retaining nut.*** Simply remove that barrel nut and replace with the Night Manager barrel nut, then install the aluminum shroud and lock down the desired accessory orientation with the AR style castle nut.

*** (I believe this should read “retaining bolt” rather than “nut,” because Mossberg 500s use a bolt for that function.)

This is a cool accessory and can allow you to easily add lights and other accessories to your scattergun without worrying about them interfering with the gun’s operation.

The MSRP for the M500 Night Manager is $97.77 and it “comes complete with everything needed to mount the extension and includes a 3-slot section of compatible Picatinny rail and fasteners.” I was unable to find this item listed for sale on their website, though.
