    I ordered it March 17 and it’s April 6. I still haven’t received it. Still waiting for delivery.

  2. Steve Roach (verified owner)

    The 410 insert has an excellent finish, plenty of extra ‘o’ rings and fits snuggly in my 18 3/4″ barrel. Very pleased with fit, finish and performance. Looking forward to the next purchase.

    This product is well engineered, excellent manufacturing and fits perfectly. It turned my grandfathers old Iver Johnson 12ga. into something I can now use and enjoy!

  4. Harvey H. (verified owner)

    Perfect customer service in helping resolve a shipping issue. The adapter I ordered is a perfect fit right out of the box and works exactly the way it was intended. I will absolutely be a return customer

  5. William Harnden (verified owner)

    These adapters are great quality. I have a .410 and 9mm 18″ adapters. They are very easy to use, and the 9mm adapter appears to be pretty darn accurate. I was able to hit what I was shooting at from about 50 yards away with a bead sight, so can’t wait to see what it’s capable of with a red dot. The customer service is great and was shipped very quickly. I live in Indiana and received it in less than a week. I’m definitely buying more when available.

    I got better patterns from this adaptor, than the H&R .410 I owned.

  18. John (verified owner)

    Service couldn’t have been better.

  19. Michael (verified owner)

    Great insert very well made! Can’t wait for 327 federal to be available. I’m like a kid waiting for his Red Rider.

  20. Tim D (verified owner)

    Very nicely made, function fine. Bought two for both barrels of my over under. Being made of steel and 18″ long, addaptors added almost two pounds to my aready heavy shotgun. Recoil was very mild. Was a bit too heavy for shooting sporting clays. I now only use one in the bottom barrel for practice days. Perhaps someday I will get brave and shorten the length from 18″ to maybe 12″ to lose some weight.

  21. Douglas (verified owner)

    Solid product,fit and finish flawless, very pleased.

  22. Anonymous (verified owner)

    Great product and a great company to do business with. Barrels are excellent very high quality the finish on the 2 i got is
    perfect. Very fast shipping and made in the usa.

  23. Jeffery C. (verified owner)

    I’m using it in a H&R Topper. It would be nice if it could stay in the barrel when action is open; It’s a minor inconvenience. Otherwise it’s a terrific add to my old shotgun; allows me to get my eight year old shooting shotguns.
