| Do I need to get a front sight adjusting tool to adjust the height of my front sight post or is there a simple way to do it with items (tools) readily at hand? Thanks....<><....:) |
| Thanks, I can depress the spring loaded detent which holds the sight in position but have had some difficulty in getting my fingers in the FSB to grab and turn the front sight post to either elevate or lower it. Any himnts on turning the front sight post? Should I even try needle nose pliers? I don't want to screw up the finish on the front sight post....<><....:) |

If it is really an issue, get a sight tool; they're cheap and readily available. Just make sure you get the A1 (five point) or A2 (four) that is correct for your rifle. A bullet tip/paperclip or other field expedient works too, but sometimes the sight can be contrary. Moon |

I wouldn't use a bullet tip unless I was in the field. You will leave copper marks on the sight, then have to take the time to clean them off. I used a bullet tip to adjust mine before I installed a red-dot scope. Unless I was in a hurry I would use something that won't leave any marks. A pin punch might work a lot better and you won't ruin a 30-40 cent round. If you are bent on using a bullet, then cut a small piece of electrical tape to stick on the part that will make contact. It shouldn't be hard to find something suitable lying around the house. |
People have been using the tips of bullets to adjust the front sight for DECADES. It takes a bit of practice but it works and does not ruin the cartridge and really who cares about "copper marks"? Which do not happen IME. And electrical tape? Are you serious? Still, the best advice is to fork out the ~$5.00 and get a sight adjusting tool. |
I'd much rather use a FMJ bullet than anything that's steel. Please do your self a favor and stay far, far away from pliers. You'll make your front sight post shiny with scratches, and that will make a pretty good glare. The marks left from a bullet are easily removed with copper solvent, and it won't get into the finish. A good sight tool would be a good investment. Especially since most of us here on ARFOM have more than 1 AR15. If you only have 1 now, rest assured you'll have more later. |
Thanks for all the help and info guys. I am a newbie but while I was building my first AR I kept thinking about November and listening to my nieghbor so I started looking for pieces parts and now have 2 AR's. And yes, a third (or more) is already on my mind....<><....

| I read somewhere that the base of the sight (actual front iron sight) should be flushed wiith the FSB shelf. But in the Army/Airforce technical manual (page 2-52 Change 4) for Mechanical Zero Procedures, it states to have the sight tip 5mm above the FSB, for Air Force Only. What is the sight tip height setting for a carbine, like a S&W MP15 or RRA Entry Tactical? I mucked around with my front sight and I think the rifle is out of whack now.... |

I always keep handy my AR-15 Universal Tool (r). This tool will: (1) Adjust front sight post on A1 and A2 models. (2) Adjust rear windage on A1 models. (3) Drop trigger guard for use with mittens. (4) Push out Takedown and Pivot Pins, as well as push out Trigger and Hammer Pins. (5) Hold in Magazine Release Button while assembling or adjusting. (6) Remove Magazine Baseplate. and many other little jobs around the AR-15. And where, you might ask, do you get one of these handy dandy AR-15 Universal Tools (r)? www.stanleytools.com/default.asp?CATEGORY=NAIL+SETS&TYPE=PRODUCT&PARTNUMBER=58-112&SDesc=2%2F32%26%2334%3B+Tip+Square+Head+Nail+Set Stanley Tools p/n 58-112 Nail Set (2/32" tip). p/n 58-912 will also work. |
