Hansel&Grendel' Wrote:LRRPF52, I always learn from your posts. You and the Rifle Editor for Shooting Illustrated turned me on to the 6.5G. Regarding your comment for clamping of the barrel for brake install/removal, here's where I'm confused as this is off the Geissele website for their Reaction Rod:
"The 556/223 Caliber Reaction Rod makes the removal and installation of barrels, flash hiders, gas blocks and hand guards much easier and simpler. The Reaction Rod is designed to be gripped in a bench vise so that the rod is either horizontal or vertical. The upper receiver is then slid onto the rod and the rod?s integral splines enter the barrel extension and secure the barrel extension from turning. This allows all the torque from barrel nut wrenches to go directly into the barrel extension. In contrast, receiver vise blocks transmit the turning force into the aluminum receiver, a good part of which passes through the small, easily distorted receiver index pin" (emphasis added).
As emphasized the install/removal of flash hiders (and assuming other muzzle devices) are said to be enabled by the Geissele Reaction Rod per their reasoning. Also, having clocked the EFAB with peel washers at 10:30 - 11:00 for a likely torque value not to exceed 20 ft. lbs., was it still possible to un-torque the extension from the barrel? I did not have to use much force when I removed the EFAB, i.e., assuming that it was pretty much equal to the approximate 20 ft. lbs. torque to install the EFAB. And, yes, I agree with your comments about PF and Mark (and his lovely wife).
EDIT: Well, here's a Shooting Illustrated article by Rifle Editor Steve Adelmann regarding muzzle device installation/removal. Over-torque (which I know that I did not do) can separate the barrel from the barrel extension when using a reaction rod or similar device. As Steve and LRRPF52 state, the best way to install/remove a muzzle device is to clamp the barrel in a vise near the work being performed, as pictured:

And this is why I use the accuwasher system. No torque and a lil locktite it's good and I can take it back off by hand with a 4 inch long pair of channel lock plyer's while holding the rifle/upper in my other hand.
