You technically want to clamp the barrel, not the lower or the upper, when changing a FH.

You technically want to clamp the barrel, not the lower or the upper, when changing a FH.
I sit down, put the weapon together, make sures its empty, then hold the receivers between my legs while cranking on the flash hider with a DPMS tool...has worked for me about 4 or 5 times now...
Good to hear I'm not the only one...:D
I give it a few squirts of Kroil ,let it sit 15 min and grab the barrel with my left hand and use a wrench in my right hand (proper wrench for the FH) and off it comes no sweat no problem ( I do have strong hands for a 57 year old ). easy as pie ,never had one I couldn't get off this way . and the Smith Vortex is the easyest to get off because there is no washer and it is a self tighting design so you never need much torque to install it .:D
You are not supposed to "torque" a Vortex, you hand tighten it and shoot it. It tightens itself.
I've used about a dozen Vortex MDs on various builds and it works quite well.
Instructions in the package specifically say torque to 10 ft pounds
Thanks for the input guys... someone over on the calguns forum was kind enough to offer the use of their vise and barrel vise block. After seeing how much effort it took to take it off, its fair to say that cmmg must've over torqued it when installing it. we had to clamp down the vise REAL hard to keep the barrel from turning with the fh when going at it with the wrench.
All the helpful comments are sincerely appreciated.
HARD TO BELEVE CMMG WOULD DO THAT,they are normaly very good about things like that .:confused:
