The Daniel Defense Rock & Lock Iron Sight Set is a fixed front and rear iron sight set for AR-15 rifles, mounting to any 1913 Picatinny top rail.
Fixed iron sights with a party trick — Daniel Defense's Rock & Lock set installs and removes in seconds, and holds zero like it's welded.
The Daniel Defense AR-15 Iron Sight Set pairs fixed front and rear sights machined from 6061-T6 aluminium with DD's patented Rock & Lock attachment system: rock the sight onto the Picatinny rail, lock it down, and it returns to position so repeatably you can strip and refit the set without losing zero. Type III hard-coat anodising protects the sights through years of service.
Fixed 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. At approximately 2.8 oz (79 g) for the pair, the weight cost is negligible.
Mounts to 1913 Picatinny rails via the Daniel Defense Rock & Lock attachment, which hooks onto the rail and clamps down rather than simply sliding on. 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.
Both sights are also sold separately — the A1.5 Fixed Rear Sight and the Rail Mounted Fixed Front Sight. If you need both, this set is the cheaper route — the set costs less than the two singles bought separately. Buy the singles only if you need one sight on its own.

The set mounts to 1913 Picatinny rails using the Daniel Defense Rock & Lock attachment, which hooks onto the rail and clamps down rather than simply sliding on. You will 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. Check that your handguard rail sits at the same height as the receiver rail, otherwise front and rear will not line up.
No, this is a fixed front and rear set, so they stay upright at all times. That makes them well suited to a dedicated iron-sight rifle, or as a permanently deployed backup where you do not mind the sight picture sitting in front of an optic. If you want sights that fold down out of the way under a scope, a folding backup set is the better choice.
Both sights are machined from 6061-T6 aluminium with a Type III hard-coat anodised finish, which is the same class of finish used on quality rail systems. The set weighs approximately 2.8 oz (79 g) in total, so they add very little to the rifle. They are made in the USA.
Nothing beyond suitable Picatinny rail space front and rear, since the Rock & Lock hardware is part of the sights. You will want a hand tool for the clamps and should zero the rear after fitting.
