Colt 6940 Barrel Nut Wrench (Page 3 of 3)
|
Mine arrived this morning. Ordered Feb 11, right at a month to get it. I checked my CC statement and saw that it wasn't charged until Mar 6, so there's that. Fit to the barrel nut is good and tight, no noticeable play. The walls could be a little thicker, but not much. The gap to slide over the barrel measures 0.865" by my caliper. An old 20" 1/9 Colt Hbar is too thick in the middle to clear the gap in the wrench. Nor will it clear the gas block/front sight base. That means if the heavier barrels are thicker than 0.865" then the gas block will have to be removed to get the wrench on. Standard profile barrels won't be a problem. No heavy 694x, M5, IAR barrels here so it will work for me but it might have been better to make it tubular for additional strength. Not going to unscrew one just to test the wrench strength. |

New video from AR15 Tech Tips unboxing his third 6940/M5 barrel wrench from Ken Elmore. It's just awesome to see all three wrenches together in the tool box. ![]() Specialized Armament (unboxing) |

Yes, I believe so. But if you are only working on lightweight or gov't profile barrels, the 8 tooth version just gets you as many teeth as possible (as always, the more the better). |

It's just awesome to see all three wrenches together in the tool box. That’s OTDR (the guy that started this thread). He was originally just in need of a 6940 barrel wrench and lucked out that Ken Elmore was willing to sell one. From there they just struck up a friendship over similar interests in quality tools, correct assembly methods and of course, Colt. |
