Discovered the hard way that the Troy front BUIS I bought is NOT designed to go on the gas block...

Are there manufacturers that make the folding front sights a little taller to be in the proper plane?

the GG&G gas block works good and does not have to fold forward.

im going threw the same delema finding a set, i almost gave up and just got a 12" forearem just so i could get a handrail height front sight and not have to rack my brains finding one that works on my gas block. I just got a MI low pro rear buis. so im looking for a front now.

MCTAR-FFR
Flip Up Front Sight Forearm Rail Model

Is for gas blocks that are the same height as the rear rail

MCTAR-FFG
Flip Up Front Sight Gas Block Mount Model


Is for gas blocks that are lower than the rear rail


Went through the opposite thing when the shop I bought my S&W ORC from just threw on sites not realizing I needed the lower height one. They took care of me but I went through 100rds playing w/ the sites wondering why I was always shooting so low.
