I'm building an Ar-15 lower and want to get a better trigger than the ones that come with the standard ar low kits. I am looking at the Jard Adjustable trigger from midwayusa. There are two triggers a large (.170") and a small (.154"). I have a Spike Tactical lower which do I need?

But ALL SPIKE TACTICAL lowers have small ones!

Colt only used large pin for a few years, and quite a few years ago.
I have one from the mid-90's that's large-pin.

be advised that the jard is a bear to install, unless you are very familiar with AR triggers. If not, I would suggest one of the drop in type.

I checked out a a Rock River two stage at a gun shop the other day and it felt very nice. I have a rock river(supposed to be) on my ar that I bought from a gun show and it feel 100% worse than the one I got to pull at the shop the other day.

The Rock River NM 2 stage makes a fine trigger once it is tuned. Edges cleaned up, polished. After that, they are as good as any of the more expensive ones. I have one in my Grendel and it is really nice, I was thinking about putting one of the Hi-Speeds in, but after I tuned it up and tried it out I decided to just stay with it, since all I wanted was a smooth, distinct, and light two stage trigger.
The best drop in has to be the Geissele. They make one for every need and purpose too. I have their 3gun in an M4 and it is amazingly fast. I'll probably use them again on the next build too. They cost more than the Rock River, but depending on the use, they may be worth it.
I have a Jard in my FAL. It is pain in the neck sometimes and I had to modify the radius on the back of the hammer and use a stronger spring on the disconnector. One I got it tuned up, it works pretty good, but the bolt still slightly snags the hammer. I'd suspect the AR trigger to be less fussy, but you still have the set screws to deal with. Only get an adjustable trigger with set screws if only plan on using it at ranges and competitions. For defense, you want a non-adjustable trigger. The RR or several of the Geisseles fit this bill (and are good for competition too).
Finally, if you have a good AR trigger, a factory one, you can fit and tune those to be superb 4.5lb triggers. I did one using just a fine Arkansas stone and a cotton polish drum on a Dremel. You have to use a hammer and trigger that do not have finished engagement surfaces, Oly is an example of what not to use, DPMS makes a cheap example of what to use. I've turned a DPMS trigger into a pretty nice single stage trigger.

Just in case you are looking to save some money and still have a real nice trigger may I suggest you try a set of JP Enterprise JPS 3.5 Enhanced Reliabiity Spring kit which sells for about $10.00 and a set of JP Enterprises anti walk pins which also sell for $10.00, so for about $20.00 you can have a simple drop in trigger job with a stock trigger and hammer. You do need the pins if you buy the spring kit, I learned this when the trigger pin kept creeping out, the improved hammer spring just did not want to hold it right, at least not on my receiver. But the diffrence is night and day.

Once you try a Geissele you will never go back. I promise. The only
thing stopping me from replacing The other triggers I have is money.
But in time.

Castingdonkey - there were a butt load of RRA knock-off trigger assemblies running around a few years back. Maybe yours is one of those or a left over from when RRA was having trouble with their own back in like '03-'05 timeframe. Futzing with them a bit really pays off and note that the design does not tolerate a lot of variation in the placement of the lower receivers hammer/trigger holes.
