Yankee Hill QDS Folding Front Sight
Why the M4-type ears, instead of the HK-type wings that wrap around the front sight? The same reason Chuck Taylor warned about the rings around HK front sights, and why Noveske was psyched when Troy released their M4-type front sight. The front sight is not necessarily centered in the ring, or semicircular wings, and in a snap-shot scenario, you might try to center the ring or wings in the rear sight, rather than the front sight itself. This would result in a bullet going somewhere you hadn’t intended.
When I first started fiddling with the sight, I was a little concerned. The button was stiff, and the sight was harder to deploy than I would have liked. After playing with the switch-sightblade (yeah, I know, sorry) for a little while, it loosened up, and it’s now quite acceptable.
You push the button on the side, it flips up, and locks in place. I'm a little afraid that a hard knock might do some damage, since it locks when unfolded, even though it doesn't need to lock since it's spring loaded. Maybe I'll take it apart and fix it so that it doesn't lock open someday.
I unscrewed the A2 front sight that came with the sight, and installed the Trijicon front sight with tritium insert that I had in the standard A-frame front sight base (that I hacked off). I got the carbine sighted in pretty quickly. The front sight isn’t hanging far above the wings, and I didn’t have to make any significant adjustments to the rear sight.
The sight comes with the required Allen wrench for mounting the sight, and it clamped onto my Midwest Industries handguard with no issues.
Although I would prefer a sight that doesn't lock when deployed, it does lock when folded, which I did want, and I wasn't thrilled with the wings or locking designs of many of the competing flip-up front sights. I took a bit of a gamble on the Yankee Hill sight, and it paid off. Next time I need a clamp-on front sight, I think I’ll be buying another one of these.
