Well worth the extra cost

Would have given 5 stars if there were instructions or a youtube video on installation. Other than that great product

Works well and finish matches but the need of removing the extension to remove the barrel is annoying. If I would have known that I would have went with a complete 7 round 1 piece tube.

I called but no one called me back! I can only load 6 rounds???

Happy I bought it to make my Mac 1014 complete and better looking, this product stands for its high quality, perfect fitment and easy install with an affordable price and reasonable shipping. 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
