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 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.

    Very pleased with this 11in. 12 gauge to .22 adapter. It works well with my ATI Nomad single shot shotgun. I’m equally pleased with the communication and fast shipping time. Planning to purchase the 9mm and .357 adapters in 11in. when they become available.

  2. MIchael S. (verified owner)

    I really like my 12 gauge to 22 magnum adapter,tested it at 25 yards in my h&r single shot with just the bead.2 inch group after clocking it from 12 to 3 o’clock.dead center about 2 ” high.For a 6″ inch adapter
    to that’s pretty 👍 good.Very well made adapter.

  3. Jose Caso (verified owner)

    I have a Harrington and Richardson sgl barrel break open 12 gauge and it doesn’t sit inside the rear of the barrel therefore the barrel won’t close. Please advise if the one that was sent was the correct one. Thanks. Jose caso

    • Chaszel (store manager)

      Good afternoon Mr. Caso. The O’ring on the chamber end will make it a little harder to push it but it should go with a little force (the amount of force will vary depending on the type of shotgun). However if this is not to your liking you can remove the O’ring from the chamber end and it should go in easier. Also if the adapter is not what you expected or you are not happy with it for any reason you can return it for a full refund. I hope this helps, if not then let me know and thank you for your business.

    Excellent product over exceeded my expectations. Very accurate.

  7. Joe (verified owner)

    Shoots fantastic. My only issue is that gloves make it impossible to pull the spent 22 out. Otherwise it’s a fantastic option.
    Make sure you go and time the adapter. Out of my iron sight single shot zeroed for slugs, it hit 3” right at 10yds off a bench rest. Turning the adapter so the .22 bore is at 9 o’clock brought the POI as close as I could to my sights. It adds no noticeable weight to my hunting kit and takes nearly no effort to swap in and out. Also got one for my buddy and he’s said the same things from his own use.

  8. Larry (verified owner)

    It shoots very good! A great addition to my adapter collection.

  9. Daniel Dearmond (verified owner)

    Again, glowing review. I purchased an 18″ and later a 11″ pocket model, both in 22 LR. I use them side by slde or put the 11 in my jacket pocket. I just love the flexibility.
    Your merch is some of my favorite part of my collection. You should be proud.

    Excellent craftsmanship, machining, finish,etc yes it has and is, blah blah. That’s not what I care about. Is the thing accurate? Can I hit what I want with it?
    Well, first shot inserted it indexed at 12 o’ clock windage perfect elevation high. Rotated to 6 o’clock. Dead on with lollipop hold. Set the target on the bead and squeeze. I’m still a little amazed that this translates over to shot gun sighting, but if your shotgun fits you your eye is the rear sight. Proceeded to bust rocks from 20 to 60 yards with all brands and types of ammo I had on hand. Probably shot 100 or so rounds, maybe 2 or 3 misses that we’re me or a kinda squib round. Spent cases slip out easily just flick em out with your fingernail. I have the 11″ .22 and it is interestingly muffled/quieted out of a 28″ 12 ga bbl.
    Conclusion: no traps, junk, or gimmicks here. This is a high quality product that will do as much as or more than can be expected. I will buy 18″ 30-30 when available.
    Excellent work
    Thank you

    High quality and shoots great. I’ll be ordering more calibers for my 12 gauge in the near future.

  19. Robert Ragar (verified owner)

    Love the versatility it gives my double barrel, more accurate than I expected, very pleased

  20. James Ballou (verified owner)

    One might think 11 inches is a relatively short barrel, but when you look at it closely, it’s actually pretty long. Darn few handguns are that long. But the Chaszel 22 Mag insert for the 12 Gauge is really a great item, for multiple reasons.

  21. Jeffrey Vicars (verified owner)

    5 shot groups at 30 yards that a nickel will cover. I’m impressed!

  22. Robert K. (verified owner)

    Very happy with these adapters! They shoot great groups, through a shotgun!!! Great quality, Excellent workmanship, Fast shipping!! I’ve bought 4 adapters, so far, Love them all, Great company! Thanks

  23. Robert (verified owner)

    Using this in a 20″ side-by-side and I gotta say it’s a lot of fun. Once I got sighting figured out I was able to get consistent results at 25 yards with just the bead.

  25. Lawrence V. (verified owner)

    I have 6 different 12 guage shotgun barrels adapters from Chaszel and they are all high quality. Though I haven’t had the chance to shoot using my new .22 lr barrel, I’m confident that it will perform as well as the other Chaszel adapters that I own. Chaszel has great customer service and quick shipping. I love their products.

    Excellent product love it.

  41. James S. (verified owner)

    Good fit as usual and good accuracy as long as the barrel is oriented properly. The only complaint was the wait for the barrel to be back in stock. If you want a certain caliber and find it in stock you better buy it.

  42. Travis (verified owner)

    Just what I wanted.

  43. David Gomez (verified owner)

  44. Steve K. (verified owner)

    Clocked at 9:00 this adapter shot straight but low. Just have to remember to aim a bit high with this one in my shotgun.

  45. James M. (verified owner)

    As always the fit, finish and workmanship are exceptional. The service is fast. The accuracy out to 100 yards is true. At 35 yards accuracy is 3/4″ MOA and at 65 yards I hit 1 1/2 spinners 80% of the time.

  46. Bradley (verified owner)

    Terrific tool just made my H&R Pardner twice as useful. I bought the 11″ version and it’s accurate enough for squirrel hunting.

    Exactly what I was looking for

  51. Brooks M. (verified owner)

    I have a few Chaszel adapters in 12 and 20 ga. I am impressed with the design, workmanship and price of all: Grade A. NO complaints on accuracy. Shooter technique, sight quality, and ammo consistency have much more effect on grouping.
    Would I purchase again? I already have. Would I recommend? I just did. Love these adapters.
