Hello... What is the diameter of the standard a2 sights? I've been looking at the ashley sights and they have .1 for the small and .230 for the large one... is this the same as the a2 sizes? I'm wanting to go same plane but yet keep the same aperture size as the a2 iron sights... thanks! Ashley Rear Sights   XS Sights have the same size holes too:  also... does anyone have any info on how to change out your rear sight? w/ another aperture? |

Don't know about the diameter, but as for swapping out the aperture, you need to remove the roll pin from the windage knob with a punch. You can actually see the pin hole in the picture above, lower left. Once the knob is off, remove the screw that holds the aperture. It's a regular flat head, on the left side of the sight. Be sure to work over a tray or something to catch any springs or bearings that may fall. Installation is the reverse of above. |
Both apertures are large. No the smaller hole doesn't make the rifle more accurate - it just makes it EASIER for you shoot precisely. But I too like a small hole aperture for precision shooting. FYI I talked with Giles Stock asking him why the Ashleys/AOs have such a large small aperture. He indicated it was designed to be used with the Ashely/AO front sight which is noticably wider than the stock front sight. If the small aperture was the same size as the A2 then it wouln't be 'usable' for anything other than target shooting (and that isn't what the AO sights were intended for). |

If you are patient you will be able to read them though. Nevermind.. just fixed that, atleast on my posts. |
