I’m getting ready to place an order with Bravo for a pair of A.R.M.S 40 B.U.I.S, question is I see two different models, the A.R.M.S low and the regular #40. What’s the difference? And what’s an all around better sight to have? TIA

If you google both the 40 and 40L  the differences are aparent.  The 40 is larger and when up resembles the regular A2  sights. The 40L on the other hand sits lower.  This is good depending on the optics you may have attached.  When folded up though the smaller apature is available you have to fold down that apature to use the large hole.

#40L (low) is just that, its a lower profile BUIS. This is beneficial for fitting a BUIS under a scope or other Optic when flipped down. The #40 is just a bit higher profile when flipped down.

Im thinking about getting a 40A2 but was wondering if the height was for F marked front sight posts or regular posts like Bushy and RRA. Anyone know? TIA.
