Default M-14 flasher castle nut....

Just got a replacement flasher to replace the after-mkt one on my gun. This flasher has part of a demilled barrel still tightly in place. Set screw out, I tapped rather significantly on the castle nut w/brass punch & managed to chip the punch more than once.

Is there a bubba way of doing this or do I have to get a correct wrench.????? job.??????

If so, where can I get one.???

1) Soak in kroil, wd-40, etc. overnight.
2) Secure (but not to the point of deformation) the demilled barrel in a vice.
3) Use castle nut pliers to remove the castle nut and therefore the FS.

If you don't have a pair of castle nut pliers, then get some before any further attempts to remove the FS. Stop with the punch; you're gonna screw something up if you ain't already. Ask here for the pliers, or, call Springfield Armory, Fulton Armory, or Orion 7. Here's a link: http://www.fulton-armory.com/flashsu...pliersm14.aspx

Sound advice from Booga. I also tap the end of FS with a rubber mallot-just enough to mot damage the splines

Get the proper pliers.

Put the assembly in the fridge (or outside) overnight. Clamp the barrel in a bench vise. Warm the castle nut with a plumbers torch.

Always get the proper tool for the job at hand...
While original GI flash suppressor wrenches are expensive there are good usable wrenches available from Brownell's for much less.

Default Changing M-14 flasher......

I asked about this here some weeks ago........fellow in Tex. sent a wrench, still couldnt get the replacement flasher castle nut loose.??? As this flasher had a section of demilled gun barrel still in place, I feel it was a factory install. Cutting the barrel off kept all the pieces together...... I had to blue wrench it, then spanner pliers, to get it off, still took my version of Hurculean effort where castle nut on my gun came off with logically reasonable effort.

Mfgs. ever locktite these.??? I could see no sign of it.........

I considered locktite the reinstall.......but I have never shot this gun in the 20yrs I have had it, probably never will.

Heck...as Issued M14's did not have lock tight. 50 years of grime might be your issue. clean the Castle Nuts threads and reassemble WIThOUT anything on the threads. Glad you bought the tool to remove the castle nut... folks often screw it up using pliers.
