AR Trigger weight increase

[Bolivar]

Hey all.

I will be shooting SR this season and want to attend NSCC. Trigger weight requirement is 5.5 lbs. My current trigger breaks at about 4.75 lbs.

Can I simply change out the springs to get the weight up to the 6.0 lbs range (a little cushion would set my mind at ease)?

Is it possible to simply buy springs to give a specified pull weight?

Do I have to look at a whole new trigger assembly?

 

[Jamie]

springs should do it

 

[Bolivar]

Any idea of where I can get 6 lb springs. I am assuming that it is not quite as simple as picking them off of a shelf? As in some trial and error might be required?

 

[Jamie]

you could try to rebend to add pressure but I would not do this without a spare set of springs

 

[Bolivar]

Hmmm, interesting. Should I focus on the hammer spring or the hammer spring or both?

 

[Gunnerlove]

I know where you were going with that.
Work both at the same time, go gradual and don't be suprised if you lose a little pull weight over time.

 

[Bolivar]

Really, you can tell what I meant, cause I can't

Hammer and TRIGGER spring (proof reading is important - Opps)

I tried the hammer spring alone and eventually bent it to the point that the trigger would not reset at all. Locked on re-cocking. Bent it back at bit so it works but did not get the weight I was looking for.

I am obviously not a gunsmith. Good thing I have an extra hammer spring.

Back to the drawing board.

Anybody got an idea where a person can buy a standard trigger? I can't justify the cost of a Geissele and I can't find any other aftermarket triggers that list a pull greater than 4.5 lbs.

What trigger are you using now?

Using the parts out of any standard lower parts kit will get you what you need.

I'd talk to Arms East or any other sponsor and see if they have the standard parts kicking around. Lots of guys have upgraded when buying a rifle and the dealer ends up with the parts a lot of the time.

I have a standard RRA that is 6 and a bit, if you want it PM me if you don't have success.

 

[blackacres]

I also have some spare trigger parts kicking around, pm me if you require some "bits" to experiment with.

Good luck.

 

[Bolivar]

Thanks for all the helpful offers. We got some good nutz around here.

Bending the springs is all you do with a Geissele trigger, the manual describes it:

I did it to the match trigger in my Stag Model 6 and it worked nicely. I bumped it up to ~6.5 lbs. It's all in the first stage, so you don't really notice it since the second stage still breaks the same as it did prior to the adjustment.

 

[Bolivar]

Yeah, bending my springs didn't work so hot. Can't get more than 5 lbs.

Thanks to a solid assist from a fellow nutter I now have an RRA trigger that breaks about 6 lbs. Has a little bit of creep but it is smooth. Considering that this is a big favor I am very satisfied and happy. Now I'll get to shoot with this trigger for the season and get used to so I can perform as well as possible with it.

This kind of stuff restores faith in CGN.
