Hello, for the 7000th time in this section, I'm a noob to AR's but rest assured I wont ask if I can shoot an AR into space or convert it into a bullpup. What I've gone and done is ordered a new stripped lower. I am wanting to buy a parts kit and looking around I have found "regular" kits, "single stage trigger" kits and "National Match 2-Stage Trigger". What the heck is the difference? I am after a light trigger pull though. Maybe some suggestions on where to find them? So far Questar looks like my best bet. But what do I know, I'm just a noob.:p
 
The regular kit gets you a single stage heavy trigger (single stage = not much movement of trigger until it fires)
A single stage trigger can be lighter (3,5 pounds instead of the stock 5+pounds) and have even less movement (travel) Timney come to mind (around 200$).
In a two stage trigger, you have some slack to take, a definite stop, then it fires with a bit more pressure. That way, lets say you have a four pounds trigger, you take the first 3 pounds away, then you only need to add one more pound for the gun to fire. It depends on you preference, but usually, a two stage is preferred for precision work. The Questar (RRA) two stage is good (around 200$ if I remember correctly) and you have better ones (Geissele comes to mind, nearly 300$).
 
The parts are different. You need to make a choice.
By changing springs, you can get a lighter trigger, but also misfires because the spring is too light to ignite the primer reliably. It works for many, but my preference goes to the trigger systems that keep full power springs inside.
 
Buy whatever parts kit you can get a Geiselle. Night and day difference between one and stock triggers.
 
Geiselle SSA is very nice yet still heavy enough for 'run and gun' stuff. I put a SSA-E in another AR and it's noticeably lighter than the SSA.

Very easy to install too.
 
I have a RRA two stage in one of my AR's. Much better than stock, and as described above, you can feel a definite bit of light slack in the first stage, then you are up against the second stage, a little bit of pressure and off it goes.
If you are on a budget, I think it would be difficult to beat in value.

My other AR has a Timney 3lb trigger. I really like the concept of the AR Timney. It's a simple drop in trigger assembly that replaces the stock firing group. One feature I like is that the stock trigger pins are re-used, but the Timney locks them in place. i.e. the pins won't be loose or rotate.
The trigger pull/break is very nice, especially on an AR.
The price of this is between the RRA and most Geiselle's.

I have read a lot of praise, high ratings and positive comments on all of the Geiselle triggers. Some day in the near future I will probably replace the RRA with an upper end Geiselle.
But they are the most pricey AR triggers.
 
As much as I am a Geissele fan I think if you are going with a SSE , its not much different pull weight from a RRA NM

htt p:// geissele.com/pdfs/TriggerSummarySheet.pdf

Either go with a SSE if you want Geissele or a super awesome Hi Speed ( not sure of your budget )

Further to that , I generally put a JP Rifle rifles "Yellow Spring Kit" ...its only $11

or if you are worried about light primer strikes ( I have not seen this with except on a 7.62x39 upper with Wolf ammo ( has deeply seated primers ) then go with the JP Red spring . It has a lighter "Yellow" trigger spring which has nothing to do with primer strike force but their Red heavier hammer spring ( but still lighter than regular )

I just put a Yellow spring in a RRA NM . Pull went from no creep crisp 4.5 lbs to a no creep chrisp 3 lbs . Takes a couple of minuites and less than $15

FYI : the reason RRA NM (National Match) does not come with lighter pull is it must meet the minimum pull weight of 4.5 lbs National Match competion shooting

Because you have not purchased your LPK already, the best value by far is go to Questars and buy

https://shopquestar.com/shopping65/shopexd.asp?id=443&bc=no

Its only a $80 premium to get the RRA NM which is a bargain . Order a JP spring kit if you want lighter pull

Conclusion, if I am doing a build that has a budget, then I generally use RRA NM with JP kit , or I go all out with a
Geissele high speed.

If anyone says that the Geisseles are all drop in as does not require fitting has not put in enough Hi Speeds . It can take while with all the fitting and adjustment. Fortunately instructions are very well written

The RRA NM has totally different trigger geometry than a stock . Which is why you can never tweak a standard trigger to anything like a RRA NM.

If you want single stage, then go with a Timney or CMC drop in.

No experience with the high speed but I have two ssa-e's and they are a 10 min install following the youtube video.

SSA and SSA-E are non adjustable so they are a straight drop in ( any trigger swap shouldn't take more than 10 mins )

Hi Speeds need to be fitted
- first you need to fit the safety / selector . The rear part of trigger is wider than stock to accomadate the adjustment mechanism. The trigger drags on selector slot and requires fitting . 3 out 5 needed this for me
- you need to check "areas of interference" as outlined in instructions
- then you need to adjust first stage pull
- then you need to set sear engangement of the 2nd stage . This takes time and helps if you have a hammer drop block so it doesn't beat the crap out of your reciever or hand
- then you set the weight adjustment of 2nd stage
- then you set overtravel adjustment

Worst part is keeping track of the 3 different size allen keys ! The slave pins and fitting pins greatly help the fitting of the Hi Speed

To me , the Hi Speed is well worth the extra $50 if you want to take the time to set it up

Some places that sell the Hi Speed gives you all 3 spring kits so you have the choice of Service , Match and DMR pull weights
