Are these spring loaded

Answered by A Guy, member, from AL, United States, on March 03, 2026

These sights are not spring loaded. The front sight has ergonomically ‘scalloped’ indentations to facilitate fingers easily grasping it to manually (required) raise the sight into shooting position. Both front and rear sight lock into position when manually raised.

Extended or standard height for absolute co-witness on a Vortex SPARC AR Gen2? Running both on FX9 8".

Expert Answer

Answered by Hunter, Gear Expert, from OH, United States, on June 22, 2023

The Vortex SPARC AR Gen 2 has a mounting base for lower 1/3 co-witness and for absolute co-witness. So the SIG SAUER Flip Up Iron Sight Set standard height will work with that red dot if using the absolute co-witness mount.
