| Hey guys, I am looking at putting together a KISS A2 rifle. I have some questions about the sights though. I can't find it, but it seems that I have read about different sight options. Is there in fact different options for not only front sight pins, but for rear apertures as well??? While I like the old skool A2, I would like to hedge my bets for my 38 year old eyes! Thanks for the input, 9080 Out |

I replaced the aperture on my detachable carry handle.
Pretty easy; just drive out the pin in the windage knob, remove the knob, spring and detent ball. Remove the old aperture and thread new one on...watch out when you're reinstalling the knob, I put a little grease on the ball and spring to hold it together during reassembly. Helps if you have an extra set of hands to hold the knob (compressing the spring) while you reinstall the pin. I used a small hammer to tap the pin back it...shouldn't take too much force to reassemble it. |

What did you replace it with? I guess what I am asking, is are there more options for apertures, along with the front pins?? Thanks, 9080 I believe the factory aperture was .060". I replaced it with a .04~", which is identical except the thru hole is a reduced size...don't remember the measurement exactly. It came in a DPMS wrapper and still has the flip capability to change to the larger 0-200m aperture. I never use it though. You have tons of options with the AR though...can buy anything from hooded match apertures to tritium CQB front posts. What do you mean by front pins? Front sight post? |
| I was calling the A frame the sight post. And the sight post a "pin". I guess a more correct way of putting it, would be: different front sight posts. As in thinner, and more precise.....hopefully. But what I really would like, is to find out if there are more options for more precise rear apertures, but still of the more "conventional" type though. Thanks for your help, 9080 |

This is the aperture I used:
http://www.midwayusa.com/viewProduct/?productNumber=690479 Will fit on an A2 and the detachable handle. Just disassemble and install. Measure how far your sight was moved over to get on paper faster when you re-zero. This is a good front post: http://www.midwayusa.com/viewProduct/?productNumber=463361 When you crank windage on the square post, it will appear larger as you are seeing it slightly from the side. Round post looks the same no matter how much wind you have dialed into the sight. |

I put on the same .046" aperature that Ricky has. I find that there is much less eye fatigue with the smaller aperature. The sight picture is not as bright, but it is clearer. I prefer a darker clear image over a bright fuzzy image. I wear glasses so I am not sure if that comes into effect.
When I used the stock .070" aperature my eyes would water after a few rounds. |

You can actually pick up sights that have interchangeable rear apertures. On my highpower service match rifle, I use .040, with a hood on it. Front sight posts, you can get narrower on too. I like to have a sight narrow enough to where it appears to me to be the same width as the black part of the 600 yard target appears to me. Easier to center up for me.
Here are some examples from Bushmaster. Sorry if I'm not supposed to post a link here, I swear I'm not the owner of the site. Match parts Threaded, hooded apertures are great, skinny front sight posts, ad also the elevation and windage adjustment can be changed from 1/2 MOA clicks to 1/4 MOA clicks. Good sights will not only help you shoot tighter, but also for a lot longer. As long as you can see the front sight post with total clarity, that's pretty much the needed deal. |
