    I am looking to mount a red dot scope and magnifier on my Bushmaster AR15. I really like these and they are in my price range

    https://www.primaryarms.com/Primary_Arms_MultiReticle_Red_Dot_Sight_PAM3M_p/pam3m.htm

    The problem is I would rather not replace my existing stock iron sights if I don't have too. Is there a way to mount these where I can still use my irons sights or will that front sight just be too high and or field of view be blocked by the scope mounts. The mounts would have to be angled as I don't have a floating rail. If I was to add a rail to the carry handle and mount the scope there how would that work out?

    Anytime I hear someone talk about mounting a red dot on a less expensive AR, Vortex Strikefire comes to mind. It's a pretty great red dot/green dot...basically an Aimpoint ripoff (similar design/features), for $150, ready to mount with a battery and 2X maginifer included. Honestly, this is the ticket for most folks in your shoes IMO. I have two mounted on $1200-1500 ARs and love them.

    I've at times flirted with the idea of ordering the Primary Arms 3X sight but don't have any actual experience with them. I've heard they're solid, which is why I continue to consider adding one. At some point this will probably result in more tangible personal evidence.

    I really don't think you'll lose with either Vortex or PA. It's just a matter of which best addresses your personal demands. Some will tell you that $300-500 must be spent for an optic you're going to depend on for 'serious business'. They probably have sound reasons for such statements...but I'd feel absolutely confident depending on my Vortex Strikefires 8 days a week, 53 weeks a year. And I do own some of the higher end optics for comparison's sake.

    Any ideas around the iron sights? Also if the underlined was supposed to be a link it didn't work. Do you have a link? Thanks for the prompt response.

    Anytime I build for me, I generally prefer a fixed front sight post/gas block with a $50 Magpul flip rear MBUS.

    I've paid more for trendier options. And it's my opinion that I paid more for less functional products in every case. The one caveat would be if you wanted a low-pro gas block with a flip front sight...in which case I'd also advise you buy Magpul.

    I believe you can find front&rear Magpul MBUS sights on EBay for like $80-90 per pair, delivered.

    I just picked up a Lucid HD7 great optic. Lifetime warranty , multi reticle , waterproof, uses one AAA battery , auto shut off , comes in black or fde, auto and manual brightness features . Great company , Vortex is great also , I own several red dots including a aimpoint , vortex, bushnell trs25, primary arms micro and I prefer the Lucid over them all because of the auto bright/ dim feature . Optics planet has them priced about the same as the strikefire . Theyalso have a 10% off code at o planet . As far as irons i also prefer magpul over my Troy and diamond heads

    Could I use the fixed front sight I have with a Magpul flip rear? It looks like the front site would be a little high.

    Show a pic of your AR and its Iron Sights. Most iron sights can 'co-witness- with the scope you will be adding. is your AR a flat top? (No carry handle, just the picitinni rail and front sight post). What does your Ar have?

    Its got the carry handle with the rear sight in the rear of the carry handle.

    Its identical to this one
    http://www.bushmaster.com/img/firearms/90298_XM-15_16M4.jpg

    Looks like I would have to remove the front sight anyway if I took the carry handle off and mounted the optics as it looks like the front sight would obstruct the view of the scope. So I guess the only option I would have without removing the front sight, adding a low pro gas block and purchasing a new rear sight would be to mount the scope directly onto the carry handle. Would this be a good idea?

    now here's my take.... if you took the carry handle off and used a real scope you would never see the front sight in the scope.

    if you put a rear flip up, or RDS of some sort you should be able to co-witness(means the front sight post will be where the dot is.)
    we have a rifle with a rear flip and iron front sight. worked just fine that way. we then added a scope and it works to perfection.

    you can find rails for about 15 bucks that would allow you to mount a RDS on top of your carry handle. but sometimes this puts the sight too high above the barrel axis and thus is not as accurate. but is very possible if its what you want.

    my advice is to choose what you want to do with the rifle.... hunting, plinking, SD, CQB?

    then choose what you like better irons, scope, RDS, RDS and irons.

    after you have these two down then you can choose a good optic... (or not) for you and YOUR rifle.

    Spend the few extra bucks and get an Aimpoint. You'll be glad you did,:)

    You could remove the carry handle, as you mentioned. And either an optical scope (3x9x40, etc) or even a red dot would work. The red dot would be focused on the tip of the post of your gun as it now sits. (If you also purchased a back up iron sight and viewed it straight on). there are many AR users out there that go this route.

    You would think that the post will block out the view of your target, but by not having to look directly straight on into the scope, (this is what's great about holographic and red dot scopes) the red dot will 'float' above the post, and not block out your lower half of the target. Bad thing is some will cover over your target if the target is something like a can at long distances, so you have to lower the power on some of these scopes that have big reticles, so the reticle is not as bright, making the target visible.

    If you bought some kind of a regular optic scope, then as mentioned by JJfuller, the scope being so close to the front post can't focus, and therefore 'ignores' the front post, or sees right through it. One of my AR's is set up like this, and the post does not interfere with the scopes field of view.

    Here are 2 variations of what I am talking about:

    The top picture is still co-witnessing through the scope, but purposely set up higher so the back up sights are not the main focal point, but as a back-up only.

    GREAT! I like variation 1. I think I will go that route. I am going to spend some time enjoying what I have first and get comfortable with my existing iron sights. Never used a peephole sight before so it is going to take some getting used to.

    I own the PAM3M Multi Reticle red dot and the PA 6x magnifier. I no longer have either of them mounted. The red dot is not bad but the magnifier makes the dot/other reticles very blurry. I'd recommend skipping the magnifier.

    Here's another option for you.

    Get a 1-4x scope. It will weigh about the same as red dot and magnifier. Choose the right reticle / eye relief and its almost as fast as a true red dot.

    Got enough cash and you can get a 1-6x or 1-8x or even a 1-10x.

    At 4x its a lot nicer than a red dot with a magnifier.

    If your batteries ever die on you, you still have a hard etched reticle.

    Yes they do. I recommend the Mark AR 1.5-4x20 Firedot-G SPR.

    Very nice piece of glass for the money. If I can get to the range this weekend, I will post a range report on it. As far as looks, it is much nicer than the Nikon M223 I owned. But I didn't like the reticle. It boils down to preference. I recommend going to Cabelas, Bass Pro Shop, Gander Mountain and fondling some glass. You'll know when you've found the one you want.

    IMHO, red dots are for CQB. Sure you can shoot 300+ with an Aimpoint or EOTech, but I'll bet you get more accuracy with a magnified optic.

    And that is why I prefer the ACOG. Excellent ++ for CQB and great for medium range.
