Frequently Asked Questions
What’s the best AR-15 trigger for general use?
For all-purpose use, look at Hiperfire EDT or Geissele SSA. They balance speed and control well.
What’s the difference between single-stage and two-stage triggers?
Single-stage has one smooth pull; two-stage gives a deliberate take-up before the break — preferred for accuracy.
Do I need a gunsmith to install a drop-in trigger?
No. Most drop-in AR-15 triggers install in minutes with basic tools and no adjustment needed.
What’s the lightest trigger pull weight available?
Some match-grade triggers offer pull weights as low as 1.5 lbs — ideal for competition.
Are these triggers legal in all states?
Most are. But always check your local compliance laws for specific features and modifications.
