What are 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.

 

380 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)

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. 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.

8 reviews for 380 12 Gauge Shotgun Adapters

  1. Jim Moore

    I have several of the Chaszel inserts. Shooting this 12 to 380 is a really great way to have fun. It is accurate enough to get 3/4″ to 1 1/4″ groups at 35 yards. And I have no problem hitting 4 inch targets from 50 to 65 yards. I can hit a 10″ target at 100 yards 10 out of 10 times consistently. To get an idea of what I’m talking about you can view my video assessment of it at https://www.youtube.com/watch?v=pNPNfdosHmg&t=240s I changed scopes since the video was done and now I’m hitting 2″ and 3″ spinners at 65 yards. I can assure you the quality of workmanship and performance of the Chaszel inserts are the best on the market.
