  1. Great--Awsome--

    Posted by George on 3rd Apr 2014

    Less kick for the ladies- more fun to take them to the field now.
    I have 7 of your adaptors,and they do a great job, no trouble at all.
    Love em.

  2. Excellent! Worked Great!!

    Posted by Mike on 7th Feb 2014

    Picked up a new used NEF 12 ga today, took it out with my new 12 to 20 ga adapter. My 14 year old son and I shot about a dozen shells, and it performed great. Can't wait to purchase some different adapters. Kudos to Dave Canterbury, for letting us know about a great product.

  3. 12 ga.to 20 ga.

    I am very happy with the 12/20 ga. adapter. It is easy and effective to use. good pattern.

  4. Thrilling!

    Posted by Unknown on 17th Jan 2014

    I was excited to try it - been looking for a product like this - realized that I only need one gun! Lots of fun, really enjoy using this adaptor - works great!
    Waiting for the development of a 12 gauge to 22-250!

  5. Now, we have a two-caliber shotgun!

    This adapter works great.It has given new versatility to an old shotgun.Now my wife can enjoy shooting her shotgun thanks to the greatly reduced felt recoil. Thanks, Corc517.

  6. Worth Every Penny

    Posted by Wes on 5th Oct 2013

    High quality, worked perfect and great price. I love being able to use one gun for multiple calibers. Great product!

  7. Well machined adapter!

    Posted by Anthony R on 29th Aug 2013

    I've owned a couple other brand adapters and they seemed really brittle, and not well machined. So when I got the Short Lane Adapter I was extremely impressed with how well machined it was, and how rugged it felt.

    I haven't had a chance to shoot it just yet, but i'm sure it'll be solid. I keep my adapters in a zippered side saddle on my H&R Single Shot 12....It's basically set up as my wilderness survival gun in case things go south while i'm out and about and need to rely on a single gun to do multiple jobs. I'll definitely be ordering more from SL in the very near future - Great work, fellas!

  8. Looks Like High Quality Throughout

    Posted by Ted W. So. Nevada on 25th Jul 2013

    When I received the 12x20ga adapter I dropped it into both top and bottom barrels of my o/u
    12 ga. I had a perfect fit and the action closed up snug just as if there was a 12 ga. shell in it. All the machining is first rate and has nice smooth edges. The 20 ga. shells drop right in and there is a minimum of movement inside the chamber. I hate to admit I have not had the time to go out and test fire it yet but if fit and finish and quality of workmanship are good indicators there are no questions in my mind that this device will work as advertised. Thanks Short Lane for offering a product that stands out above and beyond the customers best hopes. I will buy another product from this company.

  9. New Shotgun for nearly nothing

    Posted by Unknown on 12th Jul 2013

    Recently purchased the second of two 12 to 20 gauge inserts. With these two inserts I have taken a double barrel 12 gauge I seldom shot due to recoil and turned it into a 20 gauge I enjoy shooting. The weight of the 12 gauge makes the 20 gauge rounds very manageable ... guys, think home defense weapon for the wife and kids to use.

  10. Totally awesome

    Posted by Matthew Koerner on 5th Jun 2013

    I like to do skeet shooting. It worked perfectly. Was able to hit the mark and had less recoil than the 12 gauge. I liked it so much I bought the rifled 9mm and just ordered the rifled 22LR. 9mm worked well too. Can't wait to try the 22.
