Instructions For Installing Drop In AR-15 and AR-10 Trigger Groups
- If installing in a receiver that already has a trigger and hammer installed, remove the trigger pin and hammer pin and remove the trigger and hammer as well as the grip, safety selector and detent. New receivers, install the drop in trigger before mounting the grip.
- Insert the trigger pack into the fire control compartment.
- Insert the hammer and trigger pins. Anti-walk type pins work much better, as standard pins can drop out.
- Towards the rear of the trigger cassette you will see two small set screws. With the trigger and hammer pins in place, turn those set screws down to raise the trigger to the point that there is pressure created on the trigger and hammer pins which will hold them in place. This step is VERY important and will take care of the slight dimensional differences between lower receivers.
- Install the retainers on the anti-walk pins
- Insert the safety selector switch. The hammer needs to be in the cocked position. Take care as it is inserted to not push the selector into the back extension of the trigger. Replace the safety detent, spring and grip.
- At this point you can test the trigger pull and reset.
FRT Trouble shooting
FRT-15L3 Troubleshooting. Whether you are having light primer strikes, failure to feed, multi-firing, or any other issues this is the standard troubleshooting we recommend you follow.
What platform and caliber are you using?
We only guarantee that the FRT-15L3 will work in a Mil-Spec AR-15 chambered in 5.56 or .223. This does not mean it won’t work in other calibers or platforms, but we will not guarantee it or be able to troubleshoot it either.
What buffer weight do you use?
We recommend an H3 buffer with a standard buffer spring. Yes other weights work, but H3 has shown to be the most consistent for smooth and proper function.
What is your barrel length?
The FRT-15L3 has been tested and built with a 16” barrel AR-15. If you are using a shorter barrel you likely will need more gas, either by using an adjustable gas block or adding a suppressor. If your barrel is longer than 16” there is a small chance you need to decrease the gas, although this is very rare. This trigger requires fine tuning. In general the more customized the build the more adjustments are needed.
