| I see that almost every shotgun comes from the manufacturer comes with a barrel clamp, but I see alot of guns running guns without them at events. Anyone have an opinion? I really dont want to put undue stress on a $1300 shotgun by not running one. |

You don't need one. Worst case scenario you have a 12 round tube sticking out a foot past the end of an 18.5" barrel. You drop the gun or really bang it hard (like swinging a baseball bat type hard) against something and you damage the threads on the tube. If you tube is flush with the barrel there us a high probability that the barrel will stop the tube from getting banged around enough to damage the tube.
I don't typically run one with my 12 round tube and my 21" barrel. I do have a Nordic Components Clamp in my range bag with a Noveske QD sling mount on it for that rare occasion I need to sling my shotgun. |

I disagree. I have seen mag tubes shear off through fatigue and sometimes when struck against a stage prop. Its not common, but it happens.
The only reason not to have one is the concern about slug zero shifting. Some people report this, although I have NEVER had this happen with many shotguns and many clamps of many brands. I am told that, if the slug zero does shift, slightly loosening the magazine extension can resolve the issue. In my opinion, a magazine tube failure mid-match is far more catastrophic than any slight slug zero shift. I have been shooting practical shotgun matches for 30 years, and I would not run any magazine extensions without a clamp. JMHO, and worth what you paid for it.

| I have an M2 with +7 nordic tube held with a nordic clamp. To prevent weapon finish damage and provide some vibrational isolation I lined the clamp with 1/2" wide high temp silicon tape (0.06" thick I believe) ordered from McMaster Carr. Works splendidly. 400 rounds and counting and it hasn't budged or marked up the barrel or mag tube. Noticed no poi change. |

I have never seen a tube break off but I have seen the clamps change point of impact with slugs. Personal choice. If you do use one just make sure you put it back in the same place consistenly and tighten it consistenly as well. Pat |
