AR-15 Triggers

I recently bought a mil-spec lower receiver and of course the trigger STINKS. Is there any way a guy with a lot of common sense and a bit of skill can make improvements to the stock mil-spec trigger to reduce the creep and weight of pull while increasing the crispness. I can't afford $300 for a professional trigger job right now but this stock trigger is driving me NUTS! Any advice woudl be greatly appreciated.

No need for a $300 trigger job.

Certainly. Arkansas soft stone with a sharp edge, soapstone sticks. Cloth or felt buffing wheel and polishing rouge if you're careful (well, the whole thing you need to be careful). Can also use lapping compound.

1/4x28 set screw with allen wrench to adjust the takeup, and a 1/4x28 3/4" long cap screw to use for a grip screw to allow room for the set screw. If you'd happen to have a lower with a takeup screw built in that makes it easier. Some removable threadlocker to keep the set screw from changing its setting.

JP, rra, SSA, accuracy speaks,


If you're interested in a used rra 2 state let me know.

+1000

The standard AR-15 trigger can be worked with. You can go through the heat treat if you remove to much metal. The goal is not the remove metal but the make a smooth contact surface. If you understand positive and negative sear angles, that's another tool in the box. The "set screw" mod to control the amount of "creep". More advance procedures involve altering the disconnector for reset.

You can rent a AR trigger video from smartflix.com that has a lot of good info. It shows grinding, welding and heat treating.

One of the better triggers to start with is the ArmaLite Tactical Two Stage. It is very robust and has a unique design with one additional spring to allow the user the change weights with a simple spring position change, no screws to come loose.

A trigger block is a really nice to have tool for this. You can build a trigger block with a piece of hard wood, steel or aluminum. Add two trigger pins or some drill rod.
Looks like THIS.


Here's a trigger JIG.

Pick out a Geiselle that fits your needs. I like the SSA; a lot of folks like the SSA-E. Drop in and you're done.

+1 Geiselle, I have two of them and they are amazing, pretty simple to install if you have the right punch and 10 minutes to spare. Pretty expensive but worth it in my opinion... Buy once buy right

I don't think the time, effort, and risk are worth messing with the stock trigger, plus you can only do much when you start with a mil spec trigger. I think the SSA is a great option, also from time to time you see used KAC triggers for sale in the EE for ~$150.

I've used a JP and liked it.

However, I've been recently hearing that the CMC (Chip McCormick) AR triggers are pretty slick and rugged.

Just shoot it alot mil-spec triggers have a heavy pull for a reason on a combat rifle..the more you shoot it the more itll smoothe out.

How many shots does it have left till it turns into a mushy single stage?

Beats me. Seems like a problem that was blown out of scope. Not many first hand accounts recently aside from when it first happened years ago (which rra said they fixed). But I'm a single stage fan now.

Heck I remember Zhukov did/does use them a lot.

My M4 came with a LMT 2 stage trigger. They seem to be about the same as RRA.
I have a little over 3000rds fired. Still the same as day 1
