You can't ask for more! I will buy another one for my second build. Really happy customer here! And really happy with my Mac 1014. Military Armament Corporation is Awesome!

This magazine extension works well but the fit and finish of the threaded Section needs improvement. It fits fine but the screw on portions overall size is a little short which leaves exposed threads on either side of the tube extension. This is not desirable and aesthetically looks bad hence for my low star rating.

Works great as intended

I was hesitant to buy this extension based on other reviews I had read. I’m glad I bought it anyway. If there were issues before with not being able to tighten it all the way down on the threads SDS has resolved it. It was a quick and easy install and fits 7 shells tightened all the way down with no issues. It feeds the shells into the chamber reliably with no malfunctions so far. Overall I’m very pleased with what I got.

Love it fits perfect best price on the internet

Like many other comments say the new tube extension doesn't cover the threads all the way. Also it doesn't come with any instructions for the instillation.

Well, as far as functionality, this will work. But as far as design and look, it's not the greatest only because (as others have also said) the connection point in the middle of the tube is too short. It doesn't fully cover the threads on either end that it's being screwed into which is super annoying. It needs to be slightly longer to screw in farther or just lengthen the tube without threads on the ends so it would at least cover the threads it's going over. If this were corrected, it'd definitely be 5 stars. Install is pretty easy but you will probably need snap pliers and be careful when separating/reassembling. I got my hand caught between a piece and it sliced it right open. Overall I'd say 3 stars.

Well made and easy to install. Only giving 4*'s because the spring that comes with it is too long. It was trying to double feed rounds onto the ramp. Switched to the original spring and it shot fine.

Fit and finish was flawless, great investment to upgrade the performance of your scattergun. Don’t think about it, just do it. You’ll be glad you did.
