Frequently Asked Questions

What is the main advantage of a simple firearm setup?

A simple firearm setup, often using mostly stock parts, is generally more reliable and cost-effective. It reduces potential failure points compared to heavily modified firearms with numerous aftermarket accessories.

What should I be cautious of when installing aftermarket optic mounts?

Be very careful with the set screws on aftermarket Picatinny mounts, as they can be made of soft material and strip easily. Use appropriate tools and gentle pressure to avoid damaging the mount.

What is absolute co-witness with iron sights?

Absolute co-witness means your red dot or green dot sight aligns perfectly with the top of your iron sights. This allows for a seamless transition between using the optic and the iron sights for aiming.

Is a green or red dot sight better?

The preference between green and red dot sights is subjective. Some users find green dots more visible in bright daylight or against certain backgrounds, while others prefer red. Both offer rapid target acquisition.
