Excellent product very well made
Extension tube for Remington 870, item #sget-u-2. This product is very well made, fits perfect and exactly what I was looking for. From the start of ordering to delivery was very professional and timely. Great company to do business with. Thank you
Great piece for my 870
This is a great piece for my 870. The one piece tube and ring are 2oz heaver then the two piece Remington tube and ring. Very well made an looks good on my gun. I never have been a fan of the Remington tube and clamp. To me they looked out of place. Wilson Combat fixed that. Thank You
Great addition to my 870
Very well made part two ounces heavier than Remington part. I really like the one piece design and how well it locks up to the magazine tube. Finish is very good. Ordered by snail mail on Monday had it Wednesday of the next week. With all that comes with it, this is truly a good buy.
great buy
Very happy with this extension, I was a little put off by the price at first but after getting it I know its worth it, very well made and tough, fits perfect and looks great to, fits 7 2 3/4 shells no problem, definitely would buy again
Could not be happier!
I love everything about my 870 Police Magnum from the power to the wood furniture. However, 4+1 was a little lower than I wanted on a home defense shotgun. Saw that Remington offered their own extension but I also knew Wilson made one and it was a no brainer. Such an easy installation and in five minutes time I had a 6+1 Remington 870 that can also now also side mount a flashlight if needed. Couldnt be happier with the product, the price, or the customer service and delivery speed. Wilson is the best at what they do. And they do pretty much everything. Enjoy.
Great quality, easy install.
Very well made. After I took a Dremel to the dimples everything went on perfectly. Spring and follower work very well while still being easy to load. Thanks again!
Ithaca 37
Great price, material is all steel, perfect aggressive checkering and flawless finish. Hole at the end can be threaded. Why buy anything else? Perfect for Ithaca 37.
Great quality
A friend ordered one of these for an 870 build I helped him with, and a few months later I ordered a cheapo ATI extension because these were sold out. NO COMPARISON in quality. I would easily order a few more of these if they were just in stock!
Excellent Magazine Extension
I bought this magazine extension after about a month of research. I wanted a 2 shot magazine extension for my 870 express with an 18 barrel and this fits perfectly. Its a little shorter than the barrel and built like a rock so I am not worried about buying a magazine clip or hitting it against something. It installed quickly and matches the gun well. After some work to remove the divots in the guns magazine shells were feeding into the extension just fine. The spring and follower are high quality as well. Overall, I am impressed with this product and know that I made a great decision to buy from Wilson Combat.
Highly recommend
Just received it today and initial impression is wow!! The quality is way beyond my expectations. It is built to take major abuse. Install was less than a min. I had already drilled out my factory dimples prior. The extra strength spring and high vis green follower are an additional touch This is an extreme value. I highly recommend this product
Excellent product, highly recommended!!!
I ordered the 2-shot extension for my Remington 870 from Wilson because I know that Wilson Combat makes quality firearm components. The installation was straight forward, the extension itself is very high-quality, the spring and follower are of equal quality.
2 shot shotgun mag. extender.
installed in a minute. seems very well made.rock solid.however follower binds.put original follower back in, unit seems to work well.will try it out at range next weekend.
A true upgrade
I ordered the 2 shot extension without any sling attachments to replace the factory remington part because it got in the way of running a surefire weapon light forend not only did the wilson part clean up the front of the shotgun, it is build like a tank and it is easier to load the 6th round into the tube. at any price this is a great piece of gear but for what you pay it is an amazing deal.
Best Remington Magazine ext PERIOD
Just got my ext today and it is rock solid! Real nice piece!! Wouldnt even think of putting anything but a WC product on my gun.
Tough as Nails... make that TOUGHER than Nails!
The quality and craftsmanship of every Wilson Combat product Ive ever owned has always been second to none. The extension tube is no exception. Best you can buy at any price, PERIOD! Luckily, the price is very reasonable. Dont waste your time with anything else, get the best and forget the rest. Thanks Wilson Combat!
Great Value & Easy Install
I had some doubt ordering directly from the manufacturer since delivery usually would take some time - I was wrong - I received my order within 3 days. Great product for a very reasonable price. I installed on my 870 Police in ~2 min - I just received the 870 and it is my first time owning a 870 - believe or not!. Great product and extremely easy install.
