REZARF2 Posted May 1 Share Posted May 1 I have several Benelli's and I am looking at having a few barrels threaded for chokes (Also Benelli's... M4 and a cut down Nova). I have a Salvo 12 on the way and I'd like to keep them all threaded the same for simplicities sake. I don't want to add a new set of chokes and have dozens of Benelli and Beretta Chokes laying around but I do want to thread a few barrels. The chopped Nova might be too thin to thread but the M4 has some serious meet on the tube. I am having a tough time tracking down a service provider for threading to the Benelli pattern. Some searching also revealed there are 2 separate Benelli thread patterns? Can those more informed that me help me understand the difference? I have a M1 and Nova's that are already threaded... I'd like to cut my M4 to match. It appears that Benelli offers "Barrel Cutting/Choke Installation" services but I am unsure if that is threading the barrels for their chokes? Thanks in advance- Quote Link to comment Share on other sites More sharing options...
bambihunter Posted May 2 Share Posted May 2 The thread difference is all the older HK, and early Benelli USA models have the thread at the very end of the barrel. Those are called Mobil chokes and they are maybe 1" or a little more. All new ones for quite a while, I am guessing around 2002 maybe, have Crio chokes. Those are longer maybe around 1.5" and the threads are maybe 3/4" down inside the barrel. They are about the same length as many extended chokes in the Mobil style, but it all fits inside the barrel. You can do a search on the threads here and find who does the threading, cost, limitations, etc. But, for a quick recap I'll tell you that some barrels are either too thin, or they have to run another choke type that is thinner such as Rem-Choke's. Briley is who is most often recommended if I remember right for the cutting and threading. They'll keep everything legal too and make sure you don't go too short where you'll need to register it as a Short Barrelled Shotgun (SBS). If that is actually what you are after, I am not positive they do that, but they might. 1 Quote Link to comment Share on other sites More sharing options...
Steve Rose Posted May 6 Share Posted May 6 Maybe Briley can thread your factory length M4 barrel for Benelli Mobil chokes?.... The chopped Nova barrel is likely too thin for those tubes unless the barrel is quite short (an OD of around .840” minimum required). On a related note my shop still is searching for a set of the 12ga Mobil choke installation tooling that is actually available for purchase (piloted reamer and tap in new or nearly new condition). Any leads that pay off would be greatly appreciated 1 Quote Link to comment Share on other sites More sharing options...
