Hello-

Personally I can't see the issue.. but I'm not a Smith, so before I do I wamt to derisk. So, would anyone here see a fundamental flaw or issue with replacing a rear M14 match sight with a standard aperture and mechanism while keeping the thinner match front blade site? I realize it may impact accuracy given the cha ge of aperture; however, the change should only be relative to going back to a standard rear sight.

I am considering this because I dislike using match rear sights.

I've removed hooded rear sights and replaced them with non-hooded match and standard apertures, keeping the 0.062 NM front sight. Usually done for durability purposes.

Thanks, KurtC.

I did the opposite so I could install the corrective lens in the hood

Match front sights are wider than a std. front sight, not thinner.

????

Standard front sights are approximately 0.80 in width. NM sights are 0.062.

During the Glen Nelson days, there were some 0.072 NM front sights, which are highly coveted nowadays.

Point of interest...a standard front sight blade is about the same width as an E type silhouette at 250 meters, the typical BSZ.

Assembly and disassembly of the rearsight is same...wether regular or match aperture. It is like cooking a turkey..one is smaller and other bigger. The process is the same.

Do not make it more complicated than it actually is. There are only 3 moving parts. I kid - so don't think too much into it.

If you are using an SAI sight, watch out for that little detent ball.

Confession: I haven’t the faintest idea what that ball bearing actually does.

Mates with detents in back of the windage knob to provide 1/2 moa adjustment.

 

[anthonypd]

Well, I guess I’ll worry about that when the shooter is good enough to notice half moa windage adjustments with irons.

The change in aperture size doesn't have any impact on accuracy whatsoever. In any aperture type system the eye should naturally center the front sight given that your head is the same distance from the aperture. If the aperture changes, the eye will still try to center the front. How large the front is won't matter unless it is so big it obscures the target. The advantage of the NM system is that it has 1/2 minute windage adjustment and 1/2 minute elevation adjustment which is in the hood. The aperture in the hood is drilled off center and the hood has a ball bearing detent. You turn the hood one half turn to engage the detent again and the aperture has moved up or down 1/2 MOA depending on where it was before you turned it. If the hood bothers you, you can keep the NM base and windage and merely assemble the sight with a plain elevator aperture or obtain one of the M1 Garand NM apertures that do not have a hood on them. I found that when I attached my scope to the bassett mount that I have (original low style mount with a 5 degree grade built into the mount), I could no longer use a hood because it interferred with my scope. I installed a .520 original M1 NM aperture and it was just fine. No more interference with the scope eyepiece and I still kept my 1/2 minute windage and the smaller .520 aperture that I preferred. I didn't change away from the .062 NM front. The M1 garand NM aperture offers not only the finer hole but also the cross hatch back so prevent glare. As can be seen from the pics, the aperture clears the 3.5-10x40 Mark 4 Leupold that I use on my M1A.

Removing an SAI rear sight and replacing with something I ordered.

The shooter is good enough to notice but I'm not worried about going from 1/2 to 1. 😉

Agreed. Logically, it doesn't seem like a big deal but I'd rather ask first.

 

[KurtC]

The factory NM windage knob only works with the spring and ball, so be sure and save them (in case you plan on selling the NM assembly).

 

[flintsghost]

Keep in mind that the SA Match rear only works with the spring and ball. The Real GI NM sight works with a finer threaded windage knob, specifically made for the GI NM or NM2A base. The base has the fine threads inside it. Both GI types and the issue rear sight use the same elevation spindle. All elevators have the same teeth. The elevator difference is between M1 Garand which uses the longer elevator and the M14/M1A which is shorter. In order to use the Garand elevator in the M1A you must grind or file a small bevel on the lower side of the end of the elevator till it can go all to way to the bottom with the elevator knob. Not hard to do and very common to see.

 

[anthonypd]

Learn something new every day. I actually swapped out a site that had a windage knob not really working. I may have just needed to properly install the ball and spring. I assume it just slides inside the tube of the knob with the ball facing the knob?

The further you go to the right of the decimal, the smaller the fraction.
