Fancy ambi AR-15 receivers...which offer more controls, which are more useful and ergonomic?
Meaning, those two offer ambi mag releases, and ambi bolt hold open releases (actually not sure if the Sig has a hold open release on righthand side...does it? The KAC SR-15 does)
Knights KAC does and so does the Sig Saur.... but what about others?
Also, while I know about the MAD lever, I'm uncertain about the ambi mag releases... the C7a2 Norgen type, I heard discontinued, is that correct?
