Gritty AR Trigger

[Mr_Monkeywrench]

I have an ar and the trigger is SOOOO gritty. when dry firing, i can slightly pull the trigger and let it go and it stays where I pulled it until I push it back with my finger (this is before I let the hammer fall so It should automatically go back to the first position). Its originally from a DPMS parts kit. I know if i change it out it would help, but is there anything I can do to this trigger to clean it up?

[Capt. Speirs]

Polish it.

Is it difficult to do?

The trigger return spring should've prevented this from happening. Is it installed properly? Don't try and smooth it up yourself! You could create an unsafe hair-trigger situation. Send your trigger group to Bill Springfield to be smoothed up... possibly a new set of springs to go with it. He'll smooth it up for $39 with return shipping. I'd recommend the speed hammer mod for an extra $5 and a new set of springs too. Check his website, Triggerwork.net for current prices and address.

Whenever I send my stuff to him, his turn around time was about 2.5 weeks but it all depends on his workload.

I'd try and re-clean and oil all the pins and levers in the bottom receiver. Then put a tiny amount of grease under the tammer to smooth up the trigger pull. I think it'll get better with usage.

A careful polish job on an ar is not outside an amatuer gunsmiths' ability. Both my triggers are from DPMS, both are polished, and both are so freakin' sweet. They do get gritty feeling after lots of shooting tho, I just use remoil and compressed air.

Have you put oil on the trigger and hammer pins? Always try the simple things before you start spending money.

Nope.
Just get yourself a nice dremel, some polish pads and red rouge polish (jewelers polish)

Just take your time and don't go nuts.

Yeah, everytime I clean my rifle, I go through it thoroughly and clean every nook and cranny and oil it as well.

I do have a dremmel. I think im going to give it a shot. If it doesnt work out, I can always buy another. Besides I live by the phrase "how are you going to learn if you dont try it first"

Just an FYI, over oiling areas that don't need it attract grit and grime like a magnet. So if you're drenching your FCG, it will start feeling gritty in a short amount of time after firing.

Sorry to bring up a Necro-Post, but I found a simple solution to my gritty trigger problem. I went to Walmart and picked up some 220 grit sandpaper and sanded the edges of the hammer, trigger and sear. I then took some polish and a rag and began to polish every edge I could find. Put some slide glide where the hammer meets the trigger....Long story short, No more gritty trigger. Thanks again Calguns!!

Don't load a full mag for you first session at the range. Load only 2 rounds, just to make sure it doesn't double.

Good Point.

For a much smoother trigger pull, polish ( Warning : DON'T GRIND ) the sear's contact surfaces very carefully with a dremel tool using a felt wheel with some jeweler's polish. You don't want to remove metal, just polish the surfaces to a mirror finish and remove any burrs or tool marks.
