This is the official MAC product to overcome the cheesy stock 5-round tube. We all bought the Big MAC for tremendous savings over Benelli with identical features. Fifty bucks is the cheapest way to effectively fix the major fault, but the devil is in the details. Installing this tube is easy, but you quickly learn the big knurled attachment knob is too thick to allow the barrel sling ring to pass over, so you must disassemble the mag tube every time you field strip the gun for cleaning. That often involves clumsy twisting and mashing the spring back into the tube. Do you want to affect your reliability by always abusing your spring? There are more elegant offerings that address this with slick screw on tubes that freely pass through the sling ring for easy field stripping leaving the mag tube intact. You can also put in a premium Wolf Spring for even better reliability too. Isn't that little bit of extra money worth it? You decide...

Due to the large size of the mag extension coupler that screws onto the mag tube, the whole works must be disassembled to remove the barrel for cleaning. That's a pain. And if you sprung for the barrel clamp, that comes off too. Bad design which eventually plays chaos with the black finish on the barrel and mag tube.

Fits and works as advertised. Install was easy. Fits all 7 and cycles fine.

Great product. Fit and function as advertised. Spot on price point as well. As previously noted, a couple threads may be visible. This in my opinion is irrelevant. I think it actually looks a bit more "Military" in that regard. Highly recommend for practicality, price and purpose.

There are threads showing where the extension screws onto the mag. Also, the part of the extension that screws onto the mag is larger than the limiter was so when you break your MAC 1014 down you have to unscrew the extension every time and remove it because the loops on the barrel don't fit over the extension. Going to look for another alternative.

Works great. use the stock spring and save the one that comes with it as a spare, it's not necessary.

It's great.I like others have said before me.I don't particularly care for the fact that it's showing threads. I mean, I'm not a machinist but that could probably be fixed.If it wasn't for the threads showing I would give it five stars.

I really like the way it works so far. I haven’t had the chance to shoot it since I installed it so that will be seen However I do not like that it has to be removed to remove the barrel while the blocked tube did not. We will see how it works

Well worth the extra cost
