    So I took the plunge and picked up an M&P 15 OR on a good deal. Of course this model comes with no sights at all, it has a railed gas block. I'll add a red dot at some point but for now I just want some basic fixed or flip-up sights. I'd rather not invest a whole lot until I get some experience under my belt. Can I get front and rear sights for around $100 or less? I was looking at the Magpul sights but they recommend not installing the front on a gas block. Or should I just spend the $200+ and get Troy?

    I know this is pretty basic stuff for you seasoned ARers but I'm new to all this. ARs are almost too configurable. You can go crazy thinking about all the options.

    I have the same rifle, and originally just bought some MagPul BUPS, after talking with someone at MagPul they suggested I get the MagPul handguard with a bolt on rail for the front sight to mount to since I can't mount to the gas block. I later found out that I can't mount the MagPul front sight to a handguard because it's not a free float. I am now looking into buying a set of Troy BUIS, wishing I hadn't wasted the money on my MagPul BUPS.

    You could always get the Troy front sight (M4 or HK style) and then use the MagPul rear. That would come in around $140 (ar-15tactical.com has the Troy front for $83.90, and MagPul rear for $45.55 and shipping is around $7, grand total: ~$138).

    For red dots, look at Primary Arms (primaryarms.com). Their M3 and M4 clones have had nothing but excellent reviews, and they cost a fraction of what their real counterpoints cost. I actually just picked up 2 of their M3 sights on "Cyber Monday" when they had them on sale for $49 (reg $69). They shipped today and I can't wait to get my hands on them!

    The OR is one of the rare ones that have a gas block the correct height.

    Get yourself some troys.

    If the rifle will see any real use beyond the range for plinking...Get a real optic. Aimpoint in dot scopes, or a Leupold Mark AR or Trijicon if you want a variable zoom.

    Thanks for all the suggestions. ar-15tactical.com has great prices. Looks like I could go Troy front and rear for $190.

    Here is how my MP15-OR ended up...

    Sights down...

    Sights up...
    [​IMG]

    Magpul MOE hand guard
    Magpul ACS Stock
    ERGO grip
    Midwest Industries Sights
    EOTECH 512
    Vickers sling
    BCM Gunfighter charging handle
    Spikes Tactical ST-T2 heavy buffer
    (added since picture - Magpul BAD lever)

    Did a carbine class with it last month - it came through with flying colors. Several of the other folks in the class noted how lite my carbine was compared to theirs - and that's what I was looking for.

    Take care,
    Bob S.

    Replace the gas block with a YHM 9394 gasblock/folding sight combo. Includes a front sling swivel. They run about $72 (Cheaper than Dirt) Then use any rear sight or a removable carry handle.

    The OR gasblock, unlike most, is actually the correct height to line up with receiver sights.

    ......Just spend the $200 and get Troy. You will eventually anyway.

    Nice setup. That's pretty close to what I'm envisioning for mine and it seems relatively easy to do. I think I may like a longer handguard eventually (for a longer sight radius mostly). I'd have to change the gas block to do that, right? That sounds like a project for further on down the road...

    these mount around the gas block and leave it intact, there are more out there, it is just up to you how much you want to pay

    This has a Troy BUIS and a GI front sight/block. A lot less expensive than a $350 frontend changeover. That's like a case of ammo.

    Unless you're trying to build an ultralight gun, Troy's are the best out there. I'm fond of the diamond. If you want to save a little money, Midwest Industry sights are slightly less robust, but work well.

    Get the Troy's and be done with it. Buy once, cry once.

    I have MBUS on my M&P15-22, I have troy folding battle sights on my M&P15PSX.

    I'm in the same boat as you, rifle with irons first...optic someday. If they are going to be your primary sights for any length of time, get some quality sights like Troy's. Sights are your only mental/visual control over bullet placement- don't skimp.
     
  16. I bought a MP OR too. I bought a YHM front flip sight that is good to fix to the gas block. If I had to do it again.... primary arms is a great supplier. I got a set of their quad rails this week. They are 30 bucks. I would say get them and a front back set of magpul buis. For under a 100 bucks a primary arms M4 reddot is a steal, and they stand by their products. There is alot to be said for that. So for around 200 bucks you can complete your sights and have quad rails for a grip/light/etc.
    Best advice I can give you without dropping a grand.

    Which front sight style do y'all prefer, HK or M4, and why?

    I'm thinking of going with the YHM Q.D.S. flip ups. Only $139. Would the Troy Battle Sights provide any additional features over these?

    i qualified on the m4 style (given it was a M16A2 so i didn't have much of a choice) and use Troy HK,

    I prefer the HK style because i can acquire targets and line up the sights faster

    Decided to go with a Daniel Defense fixed front sight and Magpul MBUS folding rear. I've already spent way too much time researching this, I may as well just jump in and move on!

    Shot this for the first time today (this is the first time I've ever shot anything more powerful than a .22 long gun... and that was 30+ years ago!). I had zeroed in the DD fixed front sight and Magpul flip rear sight as well as I could using a Sightmark laser bore sight. Distance was 25 yards. I am pretty happy with this considering it was from a standing position without a rest of any kind. Besides the sights being almost right on (I probably have too much trigger finger so it's hard to tell if it's me or the sight alignment... though I think I'll raise the front sight post a bit - if I were flinching wouldn't more shots be low?). I was also pretty happy with the group size considering I was a virgin. Almost half of the shots were within 1.5" of the center. I should improve quickly with practice. (BTW I was pleasantly surprised at how "not loud" the AR was... I was expecting a larger boom considering I was shooting in an indoor range surrounded by concrete on all sides.)

    What fun. Shooting the Glock after this was a bit boring!
