Frequently Asked Questions

How do I ensure my AR-15 trigger installation is safe?

After installing a new trigger, always perform a function check. Ensure the rifle is unloaded, then put it on safe and try to pull the trigger; it should not fire. Then, disengage safe, rack the bolt, and pull the trigger; it should fire. An optional drop test can further confirm safety.

What are the key steps for installing an AR-15 trigger?

The process involves unloading the firearm, separating the upper and lower receivers, removing the pistol grip and safety selector, installing the new trigger cassette, reinserting the safety and pins, and finally adjusting set screws to remove trigger slack and lock the trigger in place.

Can I install a performance trigger on my AR-15 myself?

Yes, with the right tools and careful attention to detail, installing a performance trigger like the MIMTAC is a manageable DIY project. It requires basic firearm disassembly knowledge and a few common tools, such as a hex key.

What is the purpose of the adjustment screws on the MIMTAC trigger cassette?

These screws are crucial for eliminating trigger slack and ensuring the trigger is securely locked in place against the receiver. They are tightened until snug, providing a crisp trigger pull without excessive take-up.
