AIAW trigger adjustment for dummies...

Done a little searching here, and read the threads I could find, but I still need a bit more clarification.

I have an AW with a "user adjustable trigger." AI doesn't say anything in the manual on how to do this though.

From what I've figured out, you pull the skins off and adjust using the two screws that are visible when the gun is assembled (there are three total, but the third one isn't supposed to be touched by the end user.) The front most screw adjust the pull weight of stage 1, and the rear screw adjusts the sear engagement.

I have played around a bit with the front screw, but I haven't been comfortable adjusting the rear screw yet. The trigger is very crisp, and I don't want to introduce any creep. I would like to drop it to around 2 lbs.

Anyone have any further instruction on this? Just lighten up the rear screw until it gets where I want, then slam test it, safety test it, etc to make sure it doesn't accidentally go off?

Thanks,

-BM

Re: AIAW trigger adjustment for dummies...

Yes, I read that thread, it just didn't give me enough information to make me feel like I really knew what I was doing. I don't want to simulate a single stage trigger like that guy did. I simply want to reduce the weight of the second stage a bit.

if you're don't really understand what your doing its probably best to leave it alone!

the trigger is perfectly usable when it leaves the factory! the weight should be no less than 1.5 kg!

BM11,

If you don't understand the instructions then call Stacey @ AINA. He can provide you with any information you need.

The screw on/near the front of the trigger guard adjusts pull weight. Make sure you know how much you turn this screw so you can set it back to where it was in case you don't like the new setting. Adjusting this screw doesn't make it into a single stage trigger like i did with mine it just adjusts the pull weight.

Always follow the normal safety precautions (unloaded & pointed in a safe direction) & make sure you do all 3 tests listed in the instructions on the link above.

I have the ability to learn, which is why I posted this thread. I'm certain that once I gather enough information, I will understand what I am doing, and at that point I will proceed with adjusting my trigger.

</div></div>AWP- from what I could tell, the front most screw adjusts the pre travel pull weight, but doesn't have an effect on the second stage pull weight. I'm assuming that is the fuction of the second screw, am I correct? If I could get a little more info on what I am adjusting with the second screw, mechanically what it is doing, I would be confident at that point in my ability to adjust my trigger.

BM11,

The second screw adjusts sear engagement, which if turned to the right too far (maybe 4-5 turns to the right of an allen wrench inside of the guard; not complete rotations)will turn your trigger into a single stage. You can try turning it a few turns & see if you like it, just remember to count your turns so you can reset it back to where it was when you started.

FYI:
Stacey can give you exact instructions of where the factory setting are in case you forget to count the turns. I still recommend that you cal him before doing anything.Real nice/helpful person!!!

Re: AIAW trigger adjustment for dummies...

Thanks. What happens when you turn the screw to the left? What is the appropriate direction to turn it if I want to reduce the weight of the second stage pull, without turning it into a single stage?

I'll give stacey a call on monday, perhaps.

Re: AIAW trigger adjustment for dummies...

Front Straight Screw: Breaking weight
CW- Heavier
CCW- Lighter

Rear Angled Screw: Takeup
CW- Shorten
CCW- Lengthen

Those are the directions given to me by Stacey.

Re: AIAW trigger adjustment for dummies...

Really? That was breaking weight? I had a few beers when I went to adjust it, but I found that 6 CCW turns of the front screw seemed to really lighten up the pretravel so that there wasn't much weight, but didn't seem to do anything to the breaking weight. Perhaps I'll go back and try it again. I didn't see too much of an advantage to the setting I had tried, so I returned it to stock.

As for the takeup, after about 1000 dry fires plus close to 200 live fires, I have gotten used to the length of the pre travel, so I don't think I'll mess with it.

If those are really the adjustments, I'll probably just end up leaving it as-is.

Re: AIAW trigger adjustment for dummies...

Turning it (rear screw on trigger) to the left increases sear engegement, longer pull before it breaks (possibly heavier; though i have never confirmed the heavier aspect).

Turning it to the right decreases engagement & will help in reducing the felt 2nd stage pull weight, which from what i understand is what you want to accomplish.

As stated i turned mine into a single stage which i like & is safe in my rifle but may not be for others.

make sure you perform all 3 safety tests after adjusting it.

The factory setting in my opinion is perfectly fine for most people. I've met a few match shooters who leave it at the factory settings. The most important thing is a crisp break & decent pull weights, which it has from the factory. Remember that this is a great mil-spec trigger & was designed to work in all environments.

I mostly shoot off of benches & am used to 5 - 12oz triggers. If i were to use this in the field i would have left the factory setting as is.

Re: AIAW trigger adjustment for dummies...

Yes, I really like the factory pull settings quite a bit. I just wanted the opportunity to try a lower pull weight and see if I noticed a benefit.

I think I'll work on it a bit, but keep track of the adjustments I make, so that I can turn it back to stock if need be.

Do these screws require loctite, by the way?
 
#16
Re: AIAW trigger adjustment for dummies...

I never used loctite on mine, never asked Stacey about it when we talked a long time ago.

I haven't had the settings change since my adjustment. I checked it with a trigger pull gauge every few months after I did it & finally stopped checking because it never changed pull weights.

The factory settings are the way to go if you plan on shooting matches or shooting in a dirty environment.

I adjusted the front screw to the desired weight, which was CCW down to minimum. Then I adjusted the sear engagement screw, the rear angled one, until there was enough engagement so that the striker wouldn't drop when the rifle is buttstroked hard on the floor. Done.
