Why we like these:
We've always been a fan of the HK style front sight, so obviously we had to go with these in our store. We've been personally running these on our own rifle for a few years and they're great. One of our favorite features is the rear sight's aperture. Instead of a flipping aperture, you rotate the top of the rear sight. This allows it to always keep the same slim profile no matter how you have it set up, so that it always lays flat the same way on the rail when it's not deployed.
LWRC International makes extremely high quality parts and firearms. If you want backup sights that will survive the apocalypse, these are them.
Official Description From LWRCI:
LWRCI's Skirmish Sights incorporate a host of practical features into a comfortably new design. All of the sharp edges on these low-profile sights have been rounded to prevent snags and cuts to the operator. The folded profile of the sight has been kept to only half an inch. The sights lock securely into the "up" position and are lowered by pressing the button on their left sides. The sights are constructed mainly of anodized 7075 aluminum and Nicorr-coated 4140 steel.
Mountable to any 1913 picatinny rail, Skirmish Sights feature a locking helicoil which requires no additional thread lock for installation and will stand up to thousands of rounds of recoil and rugged use.
