Remove the FCG (Fire Control Group) from your AR and clean it with solvent or really hot water & crush soap to remove any oil, grease or preservative.
Grease the sears, the pin holes and the bottom curve of the hammer and reinstall.
Next, without the upper installed, work the trigger while watching your favorite show. You do this by cocking the hammer, then pull up on the hammer against the sear s with one hand and press the trigger with the other. Not too hard, though. You don't want to chip or round the corners of the sears. Degrease and repeat as necessary. This will smooth out the sear contact areas and get rid of the crunchentick feeling of the factory trigger. The trigger pull will be greatly improved.
Don't let the hammer slip from your fingers and bang against the lower. This will eventually damage your lower.
Another thing- if the trigger is installed dry, it doesn't matter how good the trigger is. It'll feel like a dump truck load of gravel found its way into the lower. Grease your triggers, boys & girls!
