Purchased a magpul mbus gen2 rear pop up sight for my bushmaster a while back. I liked it at first but after about 500 rounds it wouldn't hold a zero anymore. I was wondering if anyone else shared my problem. Its only the rear sight. I've since replaced it with an arms40 and have had no problem.

Got one on my socom ive run about 200 through it since i installed it no issue yet. Yours may just be defective contact magpul im sure they will replace it.

I've not used them but speaking anecdotally, when I asked my local LGS owner, who I do trust, about these sights, he was well less than enthusiastic.

Take that "review" for what it's worth...which obviously isn't much. Just wanted to throw it out there.

I'm sure others like them just fine. I'm partial to Troy, or they would likely have a place in my safe as I do like (and own) other Magpul products.
