Troy BUIS... Should these wiggle!?

    After all the reviews I read about these things being rock solid, I hope mine are lemons and that this isn't the standard.

    I picked up the standard TROY front and rear BUIS and have attached them to my upper. Unfortunately, although they very audibly click into place when put in the "up" position, they have front-back play (particularly on the front sight). The front especially concerns me because if I wiggle it around, the sight doesn't necessarily settle in the place where it would if I manually push it all the way forward.

    So, how tight should these be? Is any wiggle indicative of a problem, or is it a matter of how much wiggle? I was expecting these to feel like fixed sights once "locked" up and am a bit disappointed.

    Is there any adjustment required that I'm not aware of?

    Thanks in advance for any help.

    Sounds normal. There is some play so they won't bind up if dirt or sand gets in them.

    Sounds like a poor design to me. Wiggle means inaccuracy.

    Totally normal-- due to the design, all of the flip ups have some play in them.

    I bought my first Troy recently and also noticed a little play. I still have faith that it will be solid whenever I need it. I also use the MI low profile BUIS. It actually seems to have less play when in the folded position. However the Troy seems more robust in design. I use both. Both work.

    Yea my Troy BUIS has a little front to back wiggle but I think that's just the nature of flip up sights.

    They cost 2.5 times more than the MBUS,.......but I think they are stronger.
    The Troy sights are the standard to which all others are judged.

    I bought a GG&G front flip-up BUIS / gas block. There is no play at all. Positively locks up quietly and feels solid as a rock.

    It is part of the design. They are a folding backup sight. The last thing you want is for a backup sight to not fully deploy because there is some dirt in them. For a precision primary iron sight there are other options.

    Never dealt with the troy, but my Magpuls are rock solid in either the raised or lowered position.

    The Troy BUIS that came on my Noveske have zero wobble... To the OP, perhaps give Troy a call and tell them your concern?

    I know that people post a lot of opinions on the web but we are a Troy factory direct dealer. We have sold hundreds on theses sights. The movement is normal and part of the design for the reasons I have already posted. A quick call to Troy cust support will verify that.

    Thanks

    They all wiggle a bit, nothing that flips up is going to be "rock solid." If you ever see high speed film of different guns w/ the bolt going back and the brass kicking out, take a look at the sights.

    So long as they go back to the same place before you sqeeze again, you're GTG.

    Thanks to everyone for contributing. This generated alot more discussion than I expected. I have posted a small video of what is happening, so please give me your impressions, especially on the front sight.

    If you look carefully, you'll notice that the front sight does not return to it's original full upright position after I wiggle it around. The rear sight moves far less, and I guess I can live with that.

    Video...

    Again, thanks for the help.

    Not at all. If his sight is like mine, there is no side to side play, just a very slight front to back movement. No effect on the POI.

    Yeah, they all do that. No issue.

    It's great that you posted a vid. So many problems people post about on gun forums would be so much easier to understand with a pic or a vid.

    Anyway, I see what you mean about the front sight not returning to full upright. However, it's such a tiny amount that it's not going to make any difference in accuracy. Now, on mine, the wiggle is about the same, but there is enough spring tension to return it to full upright.

    I bet your sights are just tight and there is a little more friction in the pivot than some others. Put a couple drops of oil into each side of the sight and work it through it's full range of motion a bunch of times. Good chance that might free it up enough to return to full upright.

    Thanks for the suggestion. I'll give it a try. Even it it wiggles, I'd still like it to return to full upright by itself.

    If I were clever enough, I would measure the difference in height between full upright and wiggled back and figure out the theoretical difference in POI at 100 yards that the difference means. Maybe it's so small that the answer is .01 inches. Or, maybe it's .5 inches. In any case, it's likely to amount to nothing but I wish I knew.
