So I tried searching - no luck, so sorry if this is a repeat of previous threads. Does anyone have experience with improved triggers, trigger jobs (if possible), or drop in trigger assemblies for the AR 15?

I'm thinking mine could use some work. I was going to pull it apart and see if there is some fine polishing or something I could do, I was also thinking of dropping in a Timney trigger assembly, or McCormick if I can get one. Thoughts and opinions?

Thanks.
 
IMO the Geiselle DMR is the best that i have used but a very close second is my other AR with a Timney skelitonized drop in, they both make the factory trigger feel awfull.
 
Most of the regular parts-kits the AR15 are build with
cannot withstand "trigger-jobs" like other guns.
That is because only the outside of the parts are hardened,
the inside of those parts is soft and not much can be done about it.



If you choose one of the aftermarket trigger kits,
then I strongly recommend a Chip McCormick. You won't be sorry.

For a fine target trigger, Jewel is an excellent choice (if you can find one),
although installing and initial setup is somewhat difficult.
 
I've been told that about the case hardening. So no grinding, but could I at least polish the parts to slick them up a bit? I was thinking of some lapping compound and elbow/dremel grease - that's until I can find a new trigger assy. Anyone know where to get a McCormick or other good brand in Canada?

You can take crocus cloth on a M16/AR15 trigger and clean the front face.

MILSPEC triggers should be in around 57C rockwell, so cleaning up the face will not affect the harness of the parts.

I took a USGI M16 trigger from 8.9 lbs semi, and over 11lbs auto down to 5.6lbs semi, and 6.2lbs auto.

DO NOT GRIND OR DREMEL

Use a flat surface - ie piece of heavy glass, and place the crocus cloth on it, then drag the trigger face (sear) down the cloth on the same angle it has, same direction for about 12".
It does not remove a ton of material, but enough to make a bad USGI trigger into a very slick near match trigger.

When I get done a project next week I will do a pictorial
 
Thanks for the tip KevinB. I'll give the crocus cloth a try.

Anybody got a Canadian source for the McCormick or Timney drop in triggers - just in case.

Im sure the factory trigger will improve but in no way is it going to be like a drop in Timney.

You can get Timneys from 'Mysticplayer' in the dealer section, very easy to install,one piece so you cant screw it up, drops right in and is next best thing to having a M16 :)
 
I didn't like the two stage match triggers but that changed when I tried a Rock River Arms AR15. It's a great trigger and seems more study than the regular milspec trigger after I compared the parts. It gives me a similar trigger pull to some high end bolt action rifles.

I got one myself and installed it myself. Took me maybe half an hour the first time just because I was extremely careful and triple checked everything.

I haven't tried the Timneys, Jewel, or McCormick triggers so I can't accurately comment on them.
 
What do the Timney's run about usually? I have been getting tired of my AR trigger as well.

KevinB> I'll be looking forward to that pictorial :cheers:
 
I like he RRA match trigger on my AR's I find it usually sufficient for the type of shooting I do. Its a lot better than the standard triggers. I suppose if I had a longer barreled AR like a 20 or 24 incher and was looking at shooting greater than 300 yards I would invest in a better trigger like Geiselle.

Hey Kevin, any follow up on that pictorial? Thanks!
 
Yes and no.

The crokus cloth method simply smooths the sear face on trigger.

Drag the trigger face down a piece of crokus cloth, using a flat (glass) back for the crockus cloth.

This will smooth the trigger out -- do not go too deep, what happened on the guns I did is that the trigger would be good to do at those weights, but after several thousand rounds would wear thru the face of the trigger, and be unsafe. I had to cut back too far past the surface hardened (or almost thru) the material to get the trigger weight down. Lesson learned that until you get a good sample of 10+ guns going over 5k plus rounds you dont know what is really happenening.
