Having started by offering the first aftermarket shotgun magazine extensions, Choate Machine & Tool offers a diverse line of upgrade items for your shotgun projects.

Just like everything else firearms related, shotguns have seen a huge boost in popularity over the last several years. Many purchased new ones while others looked to what they already owned to fit their needs. Some had to settle for whatever was available at the time of purchase. Many of these shotgun owners will be interested in upgrades.

The plastic hull common in shotgun ammunition coupled with the very wide and flat front nearly the same width as the chamber make reliable feeding from a box magazine much more challenging than metallic rifle and pistol cartridges having nicely pointed and tapering projectiles. Shotguns with detachable box magazines are now available from companies such as Remington and Mossberg as commercial options after considerable work.

By mounting accessories on the magazine tube extension it allows use of the full length of the shotgun’s fore end, which often can be short on law enforcement type models. 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.

Currently the Night Manager is available for the Remington 870, 1100, 11-87, H&R Pardner pumps, and the Hawk 982.
