12Gauge – 20Gauge Shotgun Adapters

12Gauge – 20Gauge Shotgun Adapters allow the use of Less Powerful

Please Note:  The full length adapters will only work with 12 Gauge Shotguns with 3″ or 3 1/2″ Chambers.

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.

 

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.
We are working to make more adapters for more calibers, so you can sign up to be notified here. Thank you for your interest.

    Pattern of a 20 gauge 7.5 shot out of a 12 gauge is pretty good. Fit is good. I’m a little disappointed that I can’t rotate the adapter so that the ejector doesn’t engage the adapter. As it is, spent shell and the adapter both shoot out of the gun if you aren’t careful to trap them in a gloved hand, then press the spent shell out before loading live ammo. On the other hand, it slows you down even more, which is why I like an old break action single shot in the first place. Interesting option, functional, but maybe not extremely practical. Definitely lets you shoot 20 gauge shells in a 12 gauge if you have a need to do so!

    AWESOME SERVICE! Product arrived quickly and as described. The workmanship is of the highest degree. I plan to purchase more adapters in the near future.

    Can you use this adapter to make 20ga adapters work out of a 12ga.?

    • Chaszel (store manager)

      You can use them to do that, However the muzzle end will need to be adapted in order to achieve a tight fit or the accuracy will not be good.

    First off, love this company and their products. Purchased an 11” 12ga to .45 Colt adapter that works perfectly. Recently bought the 12ga to 20ga adapter to use in my antique top-break gun. It works, but the chamber is just a little tight. I had hand loaded some Fiocchi 2 3/4 low-brass hulls and they’re a little tight in the chamber. Tried an unloaded (but new) hull, and it was also tight.

    Again, great company and products, but I might have to hone out the chamber just a bit. Will be back for more, though. Wish they made a 26” 12ga to .22lr adapter (hint, hint…)

    This is a beautiful piece of machining. These guys continue to amaze me with the quality of their pieces and their fair prices. A labeling is very helpful and the bluing is perfect. I continue to buy more and more pieces from them and that makes both of us happy.
