Anyone ever had their rear sight aperture rachet back down to flush upon recoil?  Placing the sight 1-2 clicks up in elevation seemed to fall back down to flush on me.

Your rear sights' tension adjustment is too loose.

Read the sighting-in "How-To" pinned at the top of the page.

Get Scott Duff's "Owner's Guide" for your rifle at www.fulton-armory.com.  The same advice applies to you M1 Garand and M-1 Carbine owners, too.  Money well-spent, trust me.

I had the same problem.  I thought there was something seriously wrong with my rifle when I experienced the problem.  I sent an e-mail to Fulton Armory and the responding e-mail told me how to fix the problem.

There is a slotted head nut on the right side of the rear sight knob (windage knob) that needs to be snugged up.   Get a good fitting screwdriver to snug it up while holding the elevation knob with something that will not mar the finish.   On an older well worn rifle the teeth on the elevation disc may be badly worn and you may have to replace the elevation disc.

Well, that worked like a charm.  Thanks for the to-the-point response!

I have an M1A with a TRW barrel that produces the same groups with the same ammo. (South African R1M1)
