Magpul MBUS or A.R.M.S. 71L

Anyone compared these 2 (rear) sights?
Like the CQB notch on the 71L. Also still wondering how much the movement (MOA) is per click on either one.

Have you considered the Troy ? Much tougher unit in my opinion.

Troy would get my vote.

If you HAVE to pick from one of those, though, I’d probably go with the ARMS.

I’ve broken two Troy sights (rear folders).

If you don’t mind me asking, what were the circumstances behind the two breakages and what part of the sight failed?

From actual first hand knowledge I recommend the Version 2 Magpul. The ARMS really didn’t work well at all for me.

Reason my asking is - they both appear to be the only viable “plastic” options: being light-weight, affordable and sturdy. Both from manufacturers with solid reputations. But from what I can tell, this is where the similarity ends.

Whereas the market is saturated with Magpul products, the ARMS is far less mainstream, which in no means is an indication of it being a lesser product.

Which leads me to ask those who’ve had actual experience with both, where is their preference & why.
Another question I have is why there’s no info about sight adjustment, par click (MOA), on either, whereas this is available on most BUIS. Any reason in particular?

i like magpul

+1 for the ARMS MBUS, I’ve had one on my AR for 5-6yrs.
