Any updates on the muzzle device? I've got an OG SG542 with the flash suppressor pinned to the barrel. Just picked up one of these "flat top" SG542s with the threaded barrel. Definitely curious to see what a quality muzzle device does for it.
As a crazy aside, someone should try firing one of these with no device installed just to see what it does with regards to the accuracy. I may do that when mine arrives.
Thanks
I took mine off. Make sure that you understand that there are no Wrench-Flats on the Flash-Hider itself - The Wrench-Flats are on a SEPARATE Jam-Nut which is used to keep the Flash-Hider tight and properly indexed on the end of the Rifle. Loosen the Jam-Nut first, to take the tension off of the Flash-Hider. Turn the Jam Nut counter-clockwise staring down the rifle in the direction of bullet-travel. That ought to loosen the Flash-Hider, which can then be rotated clock-wise by hand to remove it from the end of the Rifle. Once the Flash-Hider is off, rotate the Jam-Nut Clockwise to also remove it from the rifle.
Once you have the Flash-Hider off, you will note that there is a non-threaded length of Barrel approx 2 cm long right at the end. So there are 2 cm of unthreaded barrel, and then the Flash-Hider threads begin. Standard Muzzle Devices will not accommodate the extra 2 cm of unthreaded Barrel before the threaded portion begins. Do NOT purchase a Muzzle Device without first removing the Flash-Hider to inspect the configuration of the Muzzle area of the Barrel.
After inspecting the Flash-Hider and the end of the Barrel, I am convinced that the device is properly centered on the Barrel such that bullets cannot be striking the Flash-Hider to negatively affect accuracy. This pretty much leaves the development of lighter loads as the most likely route towards improved accuracy for the SG 542.
