Greetings All from Georgia, My name is Russ I have several pistols for my carry weapon but it took longer to explain to my wife how we "need' an AR15...actually since she shoots better then I it really wasnt too too hard.
Ive watched boards, read a lot and asked tons of questions before taking tyhe plunge. I said to self, self...you dont need to spend thousands to get something im going to shoot, on average at 100 yards. That in mind I picked up a Daniels M4V5 LW. I was impressed at the way it was made, i liked and wanted the quad rails. It had an upgrade in ways of a stock, a VLTOR with a nice cheek rest. I also decided without spending a boat load of money on a Burris AR-332 Prism Sight. Not sure if anyone has any experience with it but reviews were awesome. So I did all this last week and the next day i had surgery on both feet putting me out of commission for a few more days. I never sighted in a rifle and I was told to site in at 50 yards..yes no? Ill look for some threads and read up... As soon as I figure how to add pica I will but Im sure y'all know the rifle better then myself....I look forward to learning more and having some fun  " />

The optics are excellent...i think msrp was 359...got if for 259 plus there was a 100.00 rebate on burriss' website for another 100.00. I had feet surgery so I only took 4-5 shots out the back door so it still needs to be sighted in. Im really happy so far...I have a few photos to post if I can just figure out how on the forum lol
It happened...it did really

Ok...I sighted in my DD M4V5LW with a Burris AR-223 sight at 50 yards today. It would have taken less then 10 shots to sight it in if I knew the product better and wasnt my first time sighting in Optics or shooting the AR platform. First pick is 9 rounds at 2 shots a round  " />
Next Target was a quick 4 shots at 50 yards  " />
Next target was 20 shots in succession at 50 yards  " />
The last two targets are single shots at 50 yards, quick sighted  " />
 " />
So all in all, surgery on both feet hobbling around, never had shot an AR Platform and never having the opportunity to sight in optics I didnt do so horrible. Im looking forward to shooting at a 100 yards...I do believe I'm hooked lol |

Congrats. I hope to do the same with mine this weekend.
In my perusal of the site, it seems there two most common sighting systems are 50/200 and 100. I think the data was for 55gr rounds. In the 50/200, you zero at 50 yards, and the bullet will also zero just past 200 yards. You will be within 2" of point of aim from muzzle to 250 yard or so. In the 100 yard system, the trajectory peaks at 100 years. All shots closer and farther will hit lower than point of aim. You will be 0-2" low out to 150? yards. The person who wrote this up was military, and said a low shot is better than a high shot, as you can see the bullet impact so you know easier how to correct. The article is on her somewhere.....look in the Optics section, for a pinned thread. |

Ill look that up...im learning...i thought if you sight in slightly lower 1 1/2 you will be good at a 100...didnt understand that but i figure Ill be able to sight in easily at 100 yards if im off... Sad part of this whole thing is I have my eyes looking to see whats good in a 20 inch barrel to shoot competitively...totally different animal Id think |

You can sight in with two zeros or one zero. The trajectory changes based on velocity most significantly, which changes based on your barrel length and ammo you intend to use. Sight height also affects things. Unless you're using the same configuration as Joe Shmoe, your results will be different.
For practical purposes, you sight in with two zeroes knowing your intended target. For example, say you're hunting deer and want your shots to fall within a 6" kill zone so when you have to shoot you just aim at the center of it out to some maximum distance. To do this, the peak of the trajectory over the point of aim must not exceed +3in. Your maximum distance without holdover will be where the bullet drops -3in from the point of aim. Knowing a bit about the particular round, the velocity it leaves your barrel and your sight height using whatever calculator you like you can play around until you find a zero setting where the trajectory does not exceed +3 inches over the point of aim and falls to -3 inches, say at 300 yards. If the first zero in the above example is at 65 yards and the second is at 250 yards. Zero the rifle at 65 yards. Then move the target back to confirm that the bullet lands higher than the point of aim. You will then be assured that from 0-300 yards you can just aim at the center of a 6" target and the bullet will land on target. Same goes for +/- 2in, 1.5in, etc. Just figure out what you want and get your gear set up accordingly. What some other guy did may give you a pretty good idea of what to expect, but testing yourself is the only way to know and more fun at that. |

Crazy thing about that is I kinda of understand it.. lol Im looking forward to playing that out...thank you, this isnt just about point and shoot which Im getting into and learning... |

If you want some more info, http://www.rmvh.com/MPBR.htm
I sight in all my guns without optics on them that you can easily adjust for bullet drop this way based on what I intend to shoot with them. Then all you need to know is whether the target is within range to point and shoot at the same place every time. |

This may be a way a LOT of individuals zero in their weapons and Im totally intrigued to do the same. After reading that Im not exactly sure whu anyone would zero in at 50/100 yards...this theory would suggest after reading "why", why would you even bother NOT to use MPBR. Id love to chat more about this with you or anyone else profiecent in it after I read a bit more but like I said, it just seems to make sense...gonna play with it and Ill probably PM you withint the week if you dont minds....Very cool New Old guy!

No problem. And yes, I use this on pretty much all my hunting rifles. For example, the 7mm Rem Mag and load I use for deer if sighted in at 100yrd will be about 6.5 inches low at 250 yards. If I sight in at 1.75in high at 100, I'm basically the same low at 250. I don't have any shots on my property further than 250 yards, so it's pointless to consider longer distances.
An example where I don't sight in with it would be my AR-10, which I shoot at some longer ranges. The scope has exchangeable knobs marked with zeros by distance for different bullet weights. Sight in at 100 and you're good to go by turning the knob to the proper distance. However, if I use it for deer, again and not shooting past 250 yards, I just turn the knob to the 200 yard zero which puts me around +/-2in out to 250. |

If your Burris AR332 reticle has BDC dots set up to work off of a 100yd zero and you zero for 50yrds then the BDC dots may not be very useful.
I mention this because I have the Burris AR536 and it's reticle is set up to work off of a 100yrd zero. Simply check the manual for the optic to know for sure. NICE AR! |
