Type III hard-coat anodising protects the sights through years of service.\u003c\/p\u003e\u003cp\u003eFixed sights have no springs to fatigue, no hinges to fail and no deployment step to fumble — the reason many shooters still prefer them for dedicated iron-sight rifles and hard-use backups.

You need enough continuous rail at both the front and rear positions, so a flat-top upper with a rail-topped handguard is the usual setup — and the handguard rail must sit at the same height as the receiver rail or front and rear will not line up. This is a fixed, non-folding set, so it is best suited to a dedicated iron-sight rifle or a permanently deployed backup. Rock on, lock, zero — and the set can come off and go back on without re-zeroing.\u003c\/p\u003e\u003cp\u003eBoth sights are also sold separately — the A1.5 Fixed Rear Sight and the Rail Mounted Fixed Front Sight. \u003cstrong\u003eIf you need both, this set is the cheaper route\u003c\/strong\u003e — the set costs less than the two singles bought separately.
