So whats wrong with a railed gas block?
I hear the argument it's not as "strong" as a standard FSB. Ill probably end up with the LMT 16" upper with the standard FSB. I initially was interested in the Stag 16" upper with the railed gas block. My main reason for wanting a railed gas block is that I hate having a cluttered sight picture, ie co-witness. With the railed block I could go with a flip up front sight, therefore giving me a clean sight picture. Explain to me why a railed block isn't a good option.
Thanks.
