I just bought this set from Brownells: http://www.brownells.com/aspx/NS/st...23318&title=AR-15/M16+TACTICAL+FLIP+UP+SIGHTS

They kind of look like these from GG&G:
Rear: http://gggaz.com/index.php?id=64&parents=38,40
and
Front: http://gggaz.com/index.php?id=65&parents=38,41

The front sight looks just a slight bit different on the bases. It's hard to tell from the pictures as the angles aren't the same.

Maybe the Brownells one's are an older version or something like that.

OK, got the front sight today from Brownells.

It's definitely not the same as the GG&G front sight.

The rear sight is on backorder so it'll be awhile before I can compare that one.

The Brownells front sight isn't spring loaded, but has a detent when locked up or down.

The front sight is only locked by the detent when in the up position, so not the best, but seems solidly made

I have the ASA version on my XCR and the pd uses the brownells version exclusively for BUIS. We haven't found the lack of lock in the up or down position to be a problem. It has a spring loaded check ball to help keep it in the raised position, but we are pretty pleased with them.

I do recommend a light coat of oil on them at every cleaning as they will get a little surface rust otherwise.

I like them for the 4 apertures and the real low profile compared to others, especially for the price.

Good to hear.

I like the front one, especially for the price. I'll be paying $80.00 total for both the front and rear plus shipping so that's not too bad for a front AND rear flip sight for the XCR. With shipping that's around $85. The only problem is the rear sight is on backorder for at least another week or two.

The front sight seems to be pretty stable. I tightened it up pretty good and used blue locktite on the two bolts. I snugged them up but not too tight, as it seems if I tightened them too much it affected how much pressure was required to lift or lower the front sight. I snugged up the two bolts pretty good, there will be no movement of the front sight base at all.

I also put a drop of oil on both sides where the flip portion of the front sight rotates in the base. This smoothed things up quite a bit.

I'm hoping the rear sight is good quality. I've read there are four sight apertures, two small (same size) and two large (same size) so that when you rotate between them it goes something like this small, large, small, large to quickly change for far, close, far, close shooting. Is this how your's is?

Mine has two bigger ones and two smaller ones and they do alternate, but they are all different sizes. I like it as I can use the one that best fits the light available better.

You might want to check into the front more. If it is the same kit I got from ASA the front sight will be too tall for your XCR. The one I got was for railed gas blocks, not forearms.

Whoops, that may be an issue.

The specs stated: "Front Sight clamps to Picatinny or Weaver-style rails on the gas block or handguard"

I was thinking the handguard would be the same height as the flattop.

Hmm, I may have to get another front sight then. Drats!

Did you keep the original packaging ect. as Brownells has a pretty good exchange policy?

Here's their return form: http://www.brownells.com/UserDocs/Miscellaneous/returnform.pdf

As they say: "Your Satisfaction Guaranteed. Period."

Actually, I have a DPMS LR-308 I ordered without sights a couple of years ago with a scope on it, so this could go on that one as the gas block is definitely lower than the flattop.

So no problems returning it. I'll just kepp it, but now I have to order another setup. I guess the Troy sights that Brownells has for flattop.

Juice,

I didn't see that Brownells carried the Troy Brand of sights? Am I looking in the wrong place?

Sorry.

Juice,

Don't be sorry. I just couldn't find them when I searched for them.

If you want a good supplier for the Troy sights, check out Bravo Company at:

http://www.bravocompanyusa.com/AR15-Iron-Sights-s/8.htm

They told me that they are expecting a new shipment of Troy sights in any day now. If you want a set let me know and I will get you a price.

New to the forum. First post. Just bought the XCR and want to outfit it with flip-up sights to compliment the EOTech 512.

Pardon my ignorance, but are you saying that you need to buy the front sight for railed gas block, forearm rail or flat top? Thanks for any help. 8)

I think, the front sight specifically for a flattop or at least a picitinny rail on a gas block at the same level as a flattop.

This may be a problem for the front sight I bought as it states for gas block. Normally, the gas block sits a bit lower than a flattop's picitinny rail.

The specs on mine state: "Front Sight clamps to Picatinny or Weaver-style rails on the gas block or handguard" so that can mean anything.

I'll know for sure when my rear sight arrives.

Badman,

what type/brand of sights are you looking at. They normally list the front sight as either "gas block" mount or "rail mount". For the XCR you will need the rail type mount.
