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.

    An awesome shotgun adapter to expand the usefulness and range of your firearm. The 18-inch shotgun adapter I purchased performs to dedicated rifle standards out to 30 yards which more than meets my needs and expectations.

    Love it, turns my 20 gauge single shot into a multi purpose gun and the 18 inch insert is accurate with good sights on gun. I actually shortened my barrel to accommodate these inserts. Hope to get the 357 mag one soon. Thanks guys.

    I purchased the 11inch 22lr adapter for my 20 gauge, O/U shotgun. Very easy to use and more accurate than I expected. I put out some 6inch steel plates at 25 yds to simulate small game and I was hitting them every time with no effort. It actually got boring after a while. It’s definitely worth the money as now I can have a 22lr for small game on the ground up close, and the other loaded barrel with shot and a full choke for further shots and shots in the air / trees. Note I do have a set of adjustable sights on my shotgun which were very helpful as well for consistency and having it shoot POA to POI.

    These are well machined. They go in and remove properly. They are off set in the bore so put the thinnest part down to shoot the truest. Will be getting a set in .410 when they become available.

    I have a few of your shotgun inserts in both 12 and 20 gauge. Excellent workmanship, very good communication, always prompt shipping. I recommend your product to everyone I know! I’m waiting on the 40 Smith & Wesson to 20 gauge or 12 gauge. I look forward to when they are ready and purchasing them. Keep up the good work…

    Best adapter so far

  28. Ron Huffman (verified owner)

    I shot the other day at 30, 40 and 50 yards using the bead sight on my 20 gauge and used Winchester 22 mag ammo. I recall hitting my 8″ gong with 7 of 9 shots at 50 yards and only a couple of misses at 30 and 40 yards. Shot 50 rounds total. Very pleased with the 18″ long insert. I plan to shoot paper next. Maybe squirrel hunt with it next fall.

    Hello there. So far I love the insert, even though I have not yet tried it. I did purchase the 11-inch 20-gauge 357 insert and that works well with 38 special (have not tried 357 mag. for fear of pressure issues). I have a question about the 22 cal. insert: When I inserted it into my 20 gauge, rifled slug barrel, I heard metal scraping on metal. Do you know if the insert could damage the rifling? Would it help to insert a bore guide?

    glad i bought it
