It’s a plus 1 tube
It’s ok not great, adding this makes barrel removal a nightmare. The extension doesn’t fit through magazine retainer on the barrel, requiring you to disassemble the magazine tube every time you field strip for cleaning, not the end of the world but not great. Better off just getting the Benelli full length tube.
Benelli 1014 magazine extension
The spring had to be cut down to accept 7 shots in magazine !
Quality issue !!
IT MAKES CLEANING THE GUN A HASSLE
Buyer beware, unless you read these comments from myself and others (NOT mentioned in the item listing and NOT mentioned in written in installation instruction that comes with it) - the thick ring on the extension now will require you to remove the extension and the spring/follower every time to get the barrel off for cleaning the ARGO gas and other basic maintenance. With The stock plug, you can just slide the barrel and fore grip right over the plug after removing the main screw. No more after this is installed. And if you replace the spring retainer that comes on most (mine anyway) M4s that has to be carefully pried out to remove the spring, thats an even bigger pain and also wear to that part it wasnt designed for.
Functional is about it, QC sucks!
From a cost and functionality perspective, it's great. Very easy to install and does what it's supposed to do. However since it's meant to be attached to a $2k shotgun, the attention to detail and quality control is terrible. It looks like the tube was glued to the threaded union using wood glue. I'm pretty sure it solder from the manufacturer process, but it really looks like crummy in comparison to the Benelli's fantastic fit and finish of the shotgun. If you care about the QC and have the cash you might want to consider spending $200 and ordering a one piece titanium 7 round mag tube from carriercomp.
