Description

12Gauge – 20Gauge Shotgun Adapters

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

20 Gauge Shotgun Shells together with 12 Gauge Shotguns. For 3″ Chambers.

Compatible with Break Action Shotguns such as single or double barrel shotguns.

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

    Works very will, build very good, easy to clean.

  3. Kevin S. (verified owner) –

    This device is a blessing. It patterns amazingly well in my gun. Plus, the reduced recoil makes shooting much easier on my battered, old shoulder.

  4. Mike Wilbanks –

    Picked up a couple of these adapters to use in my O/U on a Sporting Clays range. I hand picked the stations where I used them and I must say they performed better than expected. The quality of workmanship for fit and finish is A+ and the company’s customer service was extremely helpful. I have been sharing my experience with all my shooting buddies!

  5. Daniel D. (verified owner) –

    Just thrilled. My dad was a 20 ga Man. He would be tickled pink with this concept. The machine work is like jewelry . Really nice.

    Extremely satisfied with my purchase

  19. Frank Jennings –

    I measured some Fiocchi 12 gauge shells, and about the last quarter inch (next to the primer) , the diameter expanded about .006 (6 thousands of an inch). That was just enough to require an extra little push to get the shell all the way into the chamber. This is not bad. I consider Fiocchi ammo very good stuff. (Responding respectfully to Ms Louise Logar)

  20. Matthew Williams (verified owner) –

    This product jammed my barrel and damaged my extractor . My gun no longer self extracts some bird shot rounds

  21. Charles S. (verified owner) –

    What I appreciate the most was that they have not jacked up their prices like one of their competitors. Very fast shipping, great customer service. I will be shopping with them again. Thanks Cs.

  39. Jake (verified owner) –

    Great product, fantastic service. Will buy more when available.

  40. Paul (verified owner) –

    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!

  41. J. Holder (verified owner) –

    Great service, great products, I buy all the adapters that I can from Chaszel.

  42. William Thomas (verified owner) –

    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.

  43. jacobpb33 (verified owner) –

    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.

    Repeat customer. Love the price, quality, and service.

  46. Brian Lenahan (verified owner) –

    Prompt, accurate, and polite service. Great quality products, and honest prices. Don’t ever change! : )

  47. Louise Logar (verified owner) –

    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…)

  48. Frank King (verified owner) –

    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.

    exactly what I needed at a great price!
