View Full Version : AR 15 options again!

AR 15 options again!
Thinking of getting the SW "Optics Ready" model instead of the SW MOE.

Then if you order the MAGPUL stuff for about $210 and beat the price, and have BOTH sights as flippies. No bird cage.

IS the bird cage better to have???

I suppose this is EASY to do?

August 5, 2010, 11:29 AM
The A2 bird-cage doesn't do much other than a small bit of flash suppression.

The M&P OR15 has a nice barrel on it. Go with it and don't look back.

Will the MAGPUL front sight MELT on the front gas block???

Must I go with a Troy front and Magpul on the back???

August 5, 2010, 12:06 PM
I wouldn't put a plastic sight on a gas block...

If it's on a rail on the hand guard, it should be fine.

Yannkee hill makes a flip-up front sight on a gas block (all one assembly). It's $90 at Brownells.

August 5, 2010, 12:07 PM
Yes, the MBUS will melt if mounted to a gas block rail. You'd need a metal front sight, but if you're already doing that, just get a set of metal sights and be done with it.

I guess I may go with the CDNN S&W Optics Ready ($700) rather than the Bud's MOE ($1011).

My son would rather get into the OD or Gray/Green rather than Black or Brown anyway. EVENTUALLY he'll primarily use optics.

MOE gear other than sights is about $115.

I THINK the MOE rear would be fine and "in same color" - its about $50-60.

WHAT metal front sight would work best? - and be $100 or less??? I know Troys are 'the best', but what is there in a better price range that would be at least as good as a birdcage? Need to start here to shoot the rifle.

Is a good setup

Sheep dog - have you used this?

The more expensive Troy looks adjustable - is that necessary?

Yes I have it mounted on my M4 (rail height version)

What I did was changed out my hand guard to a YHM rifle length and low profile gas block. With this set up, I put the Magpul flip up front sight on it and have had no problems. In reference to the flash hider, you may want to check out the Battlecomp (http://battlecomp.com).

Here is my rifle with the above set up.....


August 5, 2010, 03:15 PM
so... this stuff should work on the S&W OPTICS READY RIFLE???

August 5, 2010, 03:25 PM
No. The YHM you have listed is for Low-pro Gas blocks, the M&P's GB is the same height as a standard quad rail would be (level with receiver picatinny mount) So you will need to get the YHM for a railed handguard.

August 5, 2010, 04:12 PM
boy, I'm confused:

This sight says:

"This durable, all steel sight attaches to standard profile railed gas blocks to give you a backup iron sight. The sight folds out of the sight line with the push of a button and flips and locks in the deployed position with ease. Mounts quickly and easily with the included thumb screw. Accepts all standard AR sight posts and hardware (included). Made in the U.S.A. with a warranty from Yankee Hill Machine. "

So the SW MP Optics Ready is NOT a standard profile railed gas block?

Just want to get one that:

a) Is fine with the MOE rear sight

b) Works with the S&W Optic Ready front gas block.

Help! Thanks.

August 5, 2010, 04:32 PM
So the SW MP Optics Ready is NOT a standard profile railed gas block?

Correct. It has a higher than normal Gas Block. YHM makes one for what you need. It's considered a "Rail Front Sight"

August 5, 2010, 04:36 PM
Got a link good buddy? (hopefully a good price).

Also, does the Troy one I posted work for the Smith OR?

August 5, 2010, 04:40 PM
This is a good sight. MI makes some goos stuff.


Here is the YHM ^^^^

Yes the Troy appears to be a rail mounted.

August 5, 2010, 05:25 PM

The REAR Magpul sight ought to be fine with all these - correct???

August 5, 2010, 05:54 PM
No bird cage.

IS the bird cage better to have???

Are you confusing the "bird gage" for the gas block sight? Both models of S&W that you described have a "bird gage" which is the flash suppressor, the thing that is screwed onto the end of the barrel......:)

August 5, 2010, 06:47 PM
I'm getting this rifle for my son, and he really wants the Foliage Gray Magpul furniture WITH the Magpul MBUS rear sight.

So... what FRONT SIGHT do we get to round our the irons on this S&W OR AR?


(I found out that the MAGPUL Front will melt on the gas block rail).


August 5, 2010, 06:53 PM
The REAR Magpul sight ought to be fine with all these - correct???

Yup. Assuming you get a "handguard rail mount" front sight, any rear sight (even a detachable carry handle) will work.

So you need the shorter of the two types of front sights.

I tend to use Midwest Industries folding sights- cheaper than the Troy, sturdier than the Magpul MBUS (not that the MBUS is junk, but even Magpul says it's a budget model). Here's a link (http://midwestindustriesinc.com/index.cfm?fuseaction=category.display&category_id=79) to the front; you want the "handguard" height one. For comparison, here's a link (http://midwestindustriesinc.com/index.cfm?fuseaction=category.display&category_id=171) to the rear (same one I have on a couple rifles) too. Note that they come in colors; you can get them in OD green or Desert Tan if it suits your fancy.

They also have a front/rear package (http://midwestindustriesinc.com/index.cfm?fuseaction=category.display&category_id=362) for less money.

If he's going to be using these sights for a while, I'd buck up and get a metal rear sight just for durability. Something like the MI package would work just great.

August 5, 2010, 08:03 PM
I put a set of YHM metal backup sights and an EoTech 512 on my M&P. Its a pretty sweet setup.

August 5, 2010, 10:18 PM
Check www.gandrtactical.com for the MOE version. I believe it's $850 minus the $100 rebate.

August 6, 2010, 02:29 PM
Hey! Are fixed sights better? http://www.danieldefense.com/?page=shop/detail&product_id=177


August 6, 2010, 03:03 PM
Those are fixed sights.

They'll be better for match shooting, if you change out the inserts.
I have a Daniel Defense custom M4, and it came with that rear sight. I now have that same rear sight mounted on my 6.5 upper. It's a nice sight, but If you don't have a sight adjustment tool, it'll be a pain trying to adjust windage on that-speaking from experience.

Get a set of Troy's. Top of the line, and if you ever want to mount optics, just fold down both sights. And if you would rather just stick with Irons, get yourself an upgrade by adding some tritium inserts.

August 6, 2010, 03:33 PM
dog: Thanks for the perspective.

I am CHEAP, and I'm trying to hold costs down, so I'll likely go with these:


I figure that they are at least as good a stock M4 sights. All we need for now. Later, Optics will likely be primary...

August 6, 2010, 03:39 PM
Midwest are second to Troy, good sights.

August 7, 2010, 05:39 PM
BTW - any advantage to the Diamond shaped model???
