Description

400 Legend Shotgun Adapters for 12 Gauge Shotguns

400 Legend Shotgun Adapters Allow a 12 Gauge Break Action Shotgun to use 400 Legend Ammo.

For 3″ Or 2.75″ Chambers

Compatible with Break Action single as well as double barrel shotgun.

400 Legend Adapters Heavy Duty Steel Construction

 

Rifle dimensions:  .390″/.400″ with 6 grooves and .120″ wide with a 1:14 twist rate

400 Legend Shotgun Adapters Comes with multiple O-ring configurations.  As a result, easily achieving a good fit for 12-gauge shotguns.

 Black Oxide coating as a result provides notably better corrosion protection (for maximum corrosion protection keep a thin coat of oil on the insert)

 Warning:   Not all shotguns are the same!  While the majority of them are capable of handling high pressure rounds, some are NOT.  Only use these rounds in shotguns that are compatible.  I recommend on any shotgun to test the first shot in a vice while out of harm’s way and to always wear eye and ear protection.  If after testing, you see the primer punctured in the round discontinue using this round and use a less powerful round. Some of these high-pressure rounds include: 45-70 gov, 357 Mag, Max, Sig, 327 Federal, 44 Mag, 9×23 Largo, 300 Blackout, 7.62×39, 7.62×25, 30-30 Win, 35 Remington, 22 Hornet and 400 Legend.  Please always be safe and aware.

 

What are 400 Legend Shotgun Adapters?

Shotgun Adapters frequently called Chamber Reducers or Shotgun Barrel Inserts. Our shotgun adapters allow you to use other types of ammunition in a Break Action Shotgun. Including double barrel and over and under double barrels in addition to the popular single barrel break action. We offer several different versions to suit your preference in ammunition, as well as length. 12 and 20 Gauge shotgun adapters are our most popular adapters followed closely by the 410. 16 Gauge is something we plan on expanding in the future.

400 Legend Shotgun Adapters

Most of our shotgun adapters come in different lengths to suit your needs. Some like the secure storage and portably of Shell length adapters. Whereas some are looking to get the most fps (feet per second) or accuracy out of their adapter. Black Oxide has become our standard finish. We can offer unfinished adapters during our production if you have requested one.

FPS (Feet Per Second)

400 Legend Shotgun Adapters
As a general rule, the longer the adapter, the more FPS it produces. However, with low-pressure rounds such as the 45 colt, the fps difference is minimal once past the 11″ length. If you are interested, here is an excellent website that gives a good idea of fps per inch BBTI. All of our shotgun adapters are entirely made in the United States and are an affordable addition to your break action shotgun. Thank you for you interest in our Shotgun Adapters or Chamber Reducers.
