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.

  1. Robert Rogers (verified owner)

    This 30-30 adapter provides as good or better accuracy out to 200 yards as my bolt action rifle. Great for deer hunting as that is what My son uses it for in my break over shotgun with scope.
    ACCURATE is the word!

  2. Michael (verified owner)

    Very accurate and powerful at 25 yards. I Purchased it mostly out of curiosity but now I’m glad I did. I can now use my old H&R 12 gauge to shoot targets as well as clay pigeons. It’s a-lot of fun. I highly recommend this product.

  34. carl m. (verified owner)

    About the o.d. dim.s why is so much metal removed behind the o-ring area it may cause barrel whip. The o-ring Groves are good at .010 sizes but what about using 90 duro instead of 70 duro. What type of barrel stock is used 4140 or 4150? Was the ejection ring not milled away like on pistol cal. Inserts. Quality of your inserts are quite good. Nice 👍 touch dating production run lots!

  47. John Myers (verified owner)

    Absolutely amazing! I did however modify it further to suit my needs better, I did a red neck Tuladyne straight jacket mod with jb weld, polished and lightly greased the shotgun barrel so that the adapter is a perfect fit to my bore now. I then reamed it to 30-30 AI and shoot 150 grain hornady A-max bullets. Sub moa groups, the 30″ shotgun barrel quiets things down for the shooter. Over all I am extremely impressed! Waiting for when 45-70 in the 24″ long adapter to become available

  48. Kevin S. (verified owner)

    I’m very happy with the barrel insert I received from you. It shoots very well, and is well-balanced in my gun. When people at the range, or online, ask about it, I make sure to give your company high marks.

    Awesome service and quality! My 30-30 adapter fits like a glove in my 12 gauge single shot shotgun! Ive had other adapters and they’re not even close to Chaszel’s quality and workmanship. Looking forward to the 9mm and .357 adapters as soon as they are available. I highly recommend Chaszel adapters!! TWO THUMBS UP 👍🏼👍🏼

  53. Daniel D. (verified owner)

    How can something like a break action with an insert be 6 times more desirable to me than a top shelf ar15 or top shelf sub gun? You Sir, are the MAN.

  54. Jeff Allen (verified owner)

    Looks great, but having trouble with consistency Evan at 25 yds., also some are tumblers? When it came it hat 2 small o’rings on the muzzle end so I was able to get it on paper at 50 yds. But not consistent. So I pulled it out, cleaning it each time and put 3 bigger o’rings that you supplied. It was worst, couldn’t get on paper at 25 yds. ??? So…I put the small orings back on but haven’t tried it yet. I dont know what else to do?

  55. Curtis S. (verified owner)

    Very nice product,keep them coming.

  56. Herman (verified owner)

    My order was shipped in 1 day. It got here in less than a week. I was waiting to test the 30-30 adapter before giving a more detailed review, but I can’t find 30-30 ammo. If it’s anything like the 45-70 adapters I got from Caszell, then I know they will perform well.

  57. Mark J. (verified owner)

    This is my third adapter from Chazel (45lc/410, 45-70, 30-30). As always. The quality and workmanship is top notch. I’m looking forward to others in the future.

    2nd adapter bought both are great products

  73. William Thomas (verified owner)

    This is a beautifully made adapter that i can only marvel at the skill it took to make. The adapter slides into the barrel of my shotgun with ease but at the same time it is a very snug fit when fully seated. The bluing is beautiful and the finish is so smooth it will amaze you. This is a product that i will proudly show to my friends.

  74. Andrew Alvarez del Castillo (verified owner)

  75. Keith Bayless (verified owner)

    I appreciate everything you’ve done! Your 30-30 and 45-70 shotgun adapters are great! I tried them out with a friend last weekend at a gun range and now he is interested in buying your shotgun adapters! I told him that you have to check for availability for certain ones but keep checking and request email notifications for when certain adapters become available!

    I haven’t had the chance to use this adaptor yet, but it looks and feels just the same quality as other of their adaptors that I have used which were great. Their shipping was fast. I’ve used 2 or three other brands of shotgun adaptors and these are the best I’ve found.

  93. michael b. (verified owner)

    Review on 11/09/2020. I bought a 357 barrel adapter this past summer and after the experience with it I decided to purchase the 30-30 when I saw it for sale a few weeks ago. Out of the box, with just a bead sight, I was able to take a coyote at around 35 yards with basic Federal ammo in my old 50 year old single shot shotgun. If they have anything available I’d recommend buying it if you’re in the market for woods gun/ farm gun.

  94. Jacob (verified owner)

    Took it out to the range. I put a box of shells thought the adapter. No signs of over pressure. The primer strikes look good. I shot a .30-30 adapter 18″ through a new England arms 12 gauge with a modified choke.

  95. Anonymous (verified owner)

    would like to see more smaller calibers 204, 22~250 ect, but we’ll made and good delivery

  96. David B. (verified owner)

    With this insert my shotgun is truly the best multi-purpose rifle ever. I can hunt upland game and birds (shot), large game and elk at close range (slug) or deer and predators at greater range (30-30). One rifle to rule them all.

  97. DG Jeffcoat (verified owner)

    Ordered the 12/30-30 adapter. I am very impressed by the accuracy! I am shooting out of a Savage 220A. Bead front sight and a slot in the rear of the frame. At 20yds I grouped 3 shots with holes touching. Moved out to 50 and placed 3 within an inch of one another. I was shooting prone with my backpack as a rest. I will definitely be buying a few more adapters.

  98. Steven Mock

    I ordered my 18″ 44 mag insert in hopes that I put drop it in my 12 gauge H&R Model 88 as a option for deer hunting. I was really surprised at how well they grouped at 50 yards with factory ammo, but since I’m a reloader I thought I would work up a accuracy load for it. With Hornady 240 xtp bullets, I am now able to put a 3 rounds in 2″ bulls eye at 60 yards. I cut the 12 gauge barrel down to 20″ so now it is a nice handling compact gun. I can’t wait to take it hunting this fall. I am convinced that anyone who has an old single barrel laying around could buy one of Chad’s barrel inserts and turn it into a great short to medium range deer rifle. If you don’t have $500 or more for a new bolt action…I think this route is an great alternative. By the way…if you have any issue with any of the products, Chad will make it right quickly . I speak from experience.

    I like the 12 gauge-30/30 adapter. I am using it in a NEF Pardner with a 22 inch modified choke barrel and it is decent. When the 20 gauge-30/30 adapter becomes availible I will but one of those as well.

    The products the 44 mag-12gauge and 30/30- 12 gauge adapters are great shooters. I now need two 30/30 20 gauge for my over and under. Also my 357/20 gauge is also a favorite shooter. This company makes the best.

  105. Mike Bruce (verified owner)

    Spoke with Chad a number of times. Ordered the 30/30 adaptor in 12 gauge and it shipped quicky, and arrived in good stead. Immediately check fired in both a Savage 24 over and under, and an H&R Pardner. The Savage cut a three shot group you could cover with a Zippo, fired standing off hand at 25 yards. The H&R with just a front bead, fired standing off hand as well, put all three in a good minute of deer at 25 yards. Very satisfied with both service and product. So much so, I did a follow up order for a second adaptor in 20 gauge!!! Had pretty much same results with it firing standing off hand at 25 yards with both an NEF 20 Pardner,.. .and a cut down 20 gauge Hatfield. All rounds minute of dead deer at 25 yards. Looking forward to getting these out on a longer shot soon, but all in all, I’d highly recommend these for quality, service and especially for the added versatility!

    After talking with Chad, I ordered one of the 30/30 inserts. Extremely satisfied with both the service and quality of this product. Literally took it straight out if the packaging and inserted into the barrel if a Savage 24F combo gun. First three rounds were fired off hand and cut a group I could cover with a Zippo at 25 yards. With some adjustment, and more shooting I expect I’ll do better. Was quite impressed. Removed the insert an fired three rounds from an H&R Pardner…all off hand…all minute of dead deer at 25 yards. Looking forward to getting some longer range shots soon. Call Chad Monday and ordered one in 20 gauge as well. Great service, great shipping, great product. Highly recommend for those looking for added versatility.👍👍👍
