KAC - Knight's Armament 300 Meter Flip-Up Rear Sight


The KAC Flip up Rear Sight, 300 meter model is the oldest and most proven rear backup iron sight on market: it was the original BUIS issued for US SOCOM's SOPMOD program. This Knight's Armament Corporation rear backup iron sight features an aluminum base, and a steel post for long term durability. The removalable polymer peep sight insert is removable for low light use, and offers excellent day time accuracy.

This is a simple, and excellent backup iron sight for any configuration of the AR-15/M16 family of rifles.

If you're anything like me, you've sat here too long, looking at this sight while trying to deny your true feelings. Maybe you've closed the tab, tried to forget it, and looked for other "cheaper" rear sights. Then you get ripped on White Claws and go back to the WO insta and see every beautifully scuffed rifle complete with a KAC rear sight. WO-Senpai ships quickly, so you won't wallow in misplaced regret after having dropped a load of cash on it -- before you know it, you'll have it in hand, on rail.

KAC is king -- it is often imitated but nothing will beat the real thing. I've beaten up a few of these sights and they never fail, so I expect nothing less than perfection. I'll admit that it was really hard to drop that much cash on a back-up sight, but should I ever need it I have no doubt that it will not fail me. As with anything KAC, you get what you pay for.

She's the tsundere of back-up sights. You can't deny her beauty, even if her price is a bit off-putting. She'll love you forever once you take the leap.
Easy install, durable as Saber with the classic beauty of Rin.
