I want to get some iron sights for my Spike's Tactical AR-15 (rear sight) before I look for optics. Aimpoint or Acog. Spike's sells a Troy Industries or I can get a Larue Tactical. So many choices all are probably O.K. but you know it has to be perfect. What BUIS would you recommend? Thanks, Mike
If you go with an ACOG, you'll be somewhat limited in your rear site, as to get the right eye releif you'll need to run the ACOG pretty far back on the rail, meaning you'll need to run a very low profile rear site.
If you go with and Aimpoint you open yourself up to a few more choices for the rear, as most Aimpoints are mounted farther forward on the rail.
I recommend Troy BUIS (folders) as well. Unfortunately they stopped making the one I really wanted ... Troy Front Folding Battle Sight (Windage/Elevation adjustable). I ordered one and waited for months before they called me and told me it had been discontinued. I almost cried. No one else (to my knowledge) makes a similar product.
When I had a couple ARs to equip with Troy BUIS, I purchased the cheaper MagPul MBUS until I could afford the Troys just so I could have something usable. Considering the cost and the plastic, they seemed like they would be ok in a pinch.
Also have to give a hat tip to the LMT Rear Sight mentioned by cosermann.
I actually sort of like my Magpul's BUIS, granted they aren't made out of machined steel like my more expensive ARMS #40 BUIS are but they are very quick to deploy & retract.
I haven't had the chance to put them through the sort of abuse that my ARMS have been through but I'm fairly confident that they are pretty rugged & will probably take quite a beating.
For the money I think the Magpuls are hard to beat, Troy's are nice too but they are kind of pricey (so are ARMS though) either way it's hard to go wrong with any of those three IMHO.
I would go with the cco its pretty much the same as the aimpoint deal. I had one when I was in Iraq n loved it. The acog is cool to my brother had one but they are more for distance. It just depends on what u wanna do with it weapon
This is what I just qualified with and I LOVE IT, maybe I just like it cause I stared at it for 9 wks. It held zero perfectly, and let me tell you I put it through its paces, it got knocked around daily had sand, mud, and humidity all day long. I know I am going to buy one for my other AR when I get back home.
One of the additional good features of the Troy sights is that the rear aperatures do not shift your elevation (i.e. they are on the same horizontal plane). If you buy less expensive sights and find you want a same-plane rear aperture, you'll have to buy an aftermarket one and install it unless what you buy already handles that.
I found an older thread that said the Navy Seals are using the LMT rear sight. $119.00 But I'll take some of your advice and wait till my ACOG gets here to make sure how much room I'll have.
I am still using the troys that indymonkey sold me and they seem like quality sights, easily adjusted, i brought them right in and was shooting decent groups with them on the Spikes tactical AR setup. Need to upgrade to some decent optics though....
