Jgun Posted December 6, 2012 Report Share Posted December 6, 2012 That looks like a good idea, wish they made one for the large platform receiver extension. Only question that comes to mind, isn't the thread for the barrel extension right hand, just like the muzzle thread? Not sure if it should be a concern, but if you were using the device to remove a stubborn muzzle brake, I'm thinking that you could theoretically break the barrel extension free. I'm thinking that for tightening or removing stuck muzzle devices, a set of soft jaws on the end of the barrel, near the muzzle device, might be a better option?

imschur Posted December 6, 2012 Report Share Posted December 6, 2012 I think in addition to locating the barrel the barrel extension pin locks the extension and barrel together. Quote Link to comment Share on other sites More sharing options...

Jgun Posted December 6, 2012 Report Share Posted December 6, 2012 I wasn't aware of that. So, the barrel pin hole is drilled through the extension and into the barrel thread eh? That means that if you apply force to the barrel by way of trying to unscrew the muzzle device, while holding the extension with the tool, if the brake doesn't want to give, all of your pressure is applied to the pin. Probably not a problem, and certainly better than holding the upper in a vice block and having the pressure thats applied to the pin by way of the barrel, bearing against the side of the pin slot in the aluminum upper. Probably not a problem, but I would still be more inclined to want to use soft jaws around the barrel near the muzzle device, if that were possible. I guess if your trying to remove a stubbron muzzle device and don't want to remove a full length hand guard, using the tool would be a better option to the upper vise block.

imschur Posted December 6, 2012 Report Share Posted December 6, 2012 I'm not 100% sure but I thought I saw it drawn as a blind hole partially into the barrel. Maybe someone more in the know can verify Quote Link to comment Share on other sites More sharing options...
98Z5V Posted December 7, 2012 Report Share Posted December 7, 2012 The barrel index pin doesn't go into the barrel - or, it shouldn't. It doesn't touch the barrel, and is only drilled into the extension itself. It's only there to index the barrel assembly into the upper. The barrel extension is torqued on the barrel at 180lb/ft, so if you've got a muzzle device that's torqued on the barrel beyond that, then it's already stripped it's threads on the barrel, or the muzzle device.The only way I can imagine breaking the barrel free from it's extension is by trying to unscrew a muzzle device that's been pinned/welded, or by breaking free a barrel extension that wasn't properly torqued in the first place.

unforgiven Posted December 7, 2012 Report Share Posted December 7, 2012 The pin used on the 14.5 is a hollow roll pin smith said if I wanted to remove B.Comp. it would just crack on twist. Quote Link to comment Share on other sites More sharing options...
