Frequently Asked Questions

What is the difference between detonation and deflagration in explosives?

Detonation is a supersonic explosion where the reaction front travels faster than the speed of sound, creating a powerful shockwave. Deflagration is a subsonic explosion, where the reaction front travels slower than the speed of sound, often characterized by burning and flame.

How do movie explosions differ from real high explosive detonations?

Movies typically use low explosives or pyrotechnics to create large, fiery visual effects. Real high explosives, like C4, detonate supersonically, producing a powerful shockwave and a dust cloud with minimal visible flame.

What are the key features of the Olight Osight XR optic?

The Olight Osight XR is a red dot optic featuring a 2/6+ MOA multi-reticle system, an enclosed emitter for durability, and a unique Collapsible Backup Rear Sight (CBRS). It utilizes an enclosed RMR footprint.

Can the Olight Osight XR be used as a backup sight?

Yes, the Olight Osight XR incorporates a Collapsible Backup Rear Sight (CBRS) feature, allowing it to function as a backup aiming solution in addition to its primary red dot function.
