    Flint,

    To begin with are you sure you want a safety selector that protrudes that far out on the side of the receiver. It is my concern that it could easily catch on garments or other items and possibly be flipped off unexpectedly creating a safety issue. There are others that do not stick out quite as far and are considerably safer in my opinion. Like the STAR SELECTOR for example. I believe you can see one in the Rock River Arms Catalog. As far as you sight question it would be best to see some pictures. Your comment about no Knob kind of threw me on what type sight you actually have. Could be the older A-1 type of sight? I responded since I have reviewed your question for several days and noticed you had received no responses. If I can help let me know!

    damn i missed this one :) gonne need pics of your rifle regarding the rear sight.

    the safety you have to remove the trigger and disconnector and the pistol grip. the pistol grip holds a spring and detent that prevents the safety from coming loose.

    i agree with sniper03 extended isnt a terribly good idea on a AR15 for the same reasons he stated.

    I dont know if this is something on different rifles, but with my build, only removing the handle will get the spring out, then a little movement of the disconnector will let the safety come right out. Didnt have to remove anything but the handle.

    As far as the sight, you might look at Brownell's AR build videos. I know they take apart and put together an A2 style sight and the windage part should be about the same as your A1. Just ignore the elevation parts.

    your right just the pistol grip. i remove the trigger and disconector before i remove the safety when i do a deep cleaning :) but yeah you dont have to remove the trigger to get the safety out.

    I'll futz with it tomorrow night because I am out of town.

    So I'll get back to everyone who was good enough to respond.

    I think it's an older style sight. Early 90's maybe?

    I'll get back to you guys.

    The A1 sight like yours goes back to the '60s... the A2 sight with the elevation wheeel came out in the early '80s when the M16A2 was introduced.

    From your pictures it looks like you want to put A2 apertures in your A1 sight. Don't know if it'll fit so make sure.

    You guys are awesome, great advice all around.

    But I am going to skip this upgrade for now. It's one of those things where it's not necessary for the time being. Going to invest in some upgraded magazines before I get a new rear sight/safety. Of course it's more of a financial decision.

    A man's gotta prioritize.

    Thanks again guys, this forum is GREAT.

    Good move Flint. I really don't see much to gain from these upgrades. You might want to look through other AR build threads for upgrades that strike your fancy.

    And like you say buying new magazines always is a good idea. And ammo, then off to the range... :p


    ETA:

    Just noticed you're from NY, is this a preban AR? Seems to have the "evil" features that NY still bans. And buying new standard capacity magazines will be a problem. You'll be limited to 10 rounds, right? Or buy preban mags too.

    Well, it is a pre-ban AR.

    I have a ton of pre-ban magazines. They are mostly standard mil-spec mags but they are pretty old. I am going to buy new followers and padded base plates.

    Also take them a part and clean em up real good.

    Ah, now I understand...

    Yeah those Magpul Gen 3 followers really smooth up the old GI mags. Most of mine have them installed.
