LWRCI's new Skirmish Sights incorporate a host of practical features in an innovative new design. All the sharp edges on these ultra-low profile sights have been rounded to prevent snags and cuts to the operator, while the folded profile of the sight has been kept to only half an inch. Both sights can be raised using gross motor skills. The sights lock securely in the up position and are lowered by pressing a button on their left sides. The sights are constructed for 7075 aluminum which is hard coat anodized and 4140 steel that is then treated with our NiCorr surface conversion technology. The 7075 aluminum is much harder and stronger than the 6000 series aluminum used in other manufacturers' sights. Additionally, the bearings and detents are all hard chromed making these sights nearly impervious to corrosion. Mountable to any 1913 picatinny rail, the LWRC International Skirmish SIghts feature locking helicoil which requires no additional thread lock for installation and will stand up to thousands of rounds of recoil and rugged use.
