Internals for AR-15 lower: whose and where to buy??
Bought me a couple AR lowers (courtesy of Obama). Do they sell the internals (trigger and such) in a kit? If so, which brand and where to buy?

Thank you,

They are called lower parts kits (LPK). Lots of folks have them (by such makers as DPMS and RRA). Have used RRA parts in two lowers. Have worked out well.

One seller is: http://www.adxtactical.com/store/pc/home.asp

Look at http://www.ar15armory.com or http://www.AR15.com for information on putting them together. Nice information here too: http://texaspredatorposse.ipbh...9c71330a28d24d374c57

Most LPK's are manufacturerd by CMT and rebranded by the like of STAG and RockRiver. I've used RR and lots of STAG with no out of spec parts.

If it matters, NOVESKE uses CMT LPK's. Enjoy!

Best upgrade is an adjustable trigger. Mine has a JP Enterprises without the lightweight hammer. I just ground off the large hook of the stock hammer to lower the weight. The JP breaks sharply and doesn't have nine miles of gritty creep like the stocker. Get one-- you'll love it...

Good AR triggers are not cheap ... not like a Timney trigger for a Mauser. They can in fact get VERY expensive (very nice, but VERY expensive).

One approach to avoid the expense and get a pretty decent trigger is to work with Bill Springfield http://triggerwork.net/ . His work is universally praised and the price is right.

I clean up my own triggers. Polish the angled surface on the trigger bar to a mirror finish. That's it.

Use a fine whetstone, soft cotton Dremel wheel and a polishing compound such as Flitz or JB's Bore paste.
Use light pressure to avoid going through the surface hardening.
No cutting of the springs like some trigger tutorials advocate.

Makes for a very nice smooth trigger. Takes about 15 minutes to do.

As another poster said, One LPK is about the same as another. I've had good luck with Stag, Del Ton and DPMS.
The hard part is finding a kit in stock.
A quick check of the internet showed that PK Firearms, Bravo Company USA and Global Tactical all had DPMS lower parts kits in stock.

If you go with a DPMS lower parts kit, chances are close to 100% that it'll be missing ... something. ALL three I've seen were short. Happily, I had enough gazornahickeys rolling around in the parts drawer to get 'em working.

I bought my LPKs from Del Ton. Del Ton gets the kits from DPMS and repackages them with Del Ton markings. Never had a part missing...Yet.

It does help to have lots of spare little parts laying around. Especially that little pin that likes to fly across the room and vanish.

Absolutely +1. I've had many done by Bill. Great guy to boot. I like his work on a standard factory trigger better than LMT or RR 2-stage. Bills less than $50~~

As posted above most of the parts for the ar are made by a few companies and then re-branded. I wouldn't spend too much time worrying about which lower parts kit you order. However, the triggers do range from tolerable to downright ugly. I've got a RRA ar-15 with the two stage match trigger that isn't too bad. However, I got the standard trigger for my dpms ar-10 and it is miserable. Upgrading to any of the top aftermarket triggers (Giselle, Timney, Jewel, etc...) will make a huge difference.
