Or are they all the same?
In theory they are the same, in reality, they are not.
Anytime parts are machined to the thousandths of an inch there will be problems. even the top notch manufacturers can have a bad day and have a few parts go out that are out of spec.
Google each manufacturer for reviews and see which kits keep getting the best reviews. Every AR owner will say their kit is the best so you are going to get a lot of get this one it's the best or stay away from them cause they are junk. Do some research on your own, it will become apparent which ones to buy.
I would just buy a name brand... but I read a few good comments about Wilson Combat LPK's and they're only $50 on their site.
I have been looking at the PSA kits. Are they any good?
I just built my first AR using a PSA lower parts kit and had zero issue with any of the parts fitting in a DPMS stripped lower. I got the "Premium Lower build Kit" and everything went together well.
I use Spikes and PSA LPKs exclusively. You can't go wrong with either one.
Great quality and good trigger right out of the box on both of them.
May have been a fluke,.....but I had a DPMS lower parts kit's trigger pin
break withing 2K rounds fired!
Awesome, thanks guys. I think I'm going to buy a roll pin punch set just to make it easy on my first build.
I wasn't going to put any brand names in but since you asked, I've done 3 PSA lpk installs and have been extremely pleased with one exception, the MOE lpk's did not include the lock washer for the screw in the grip and I had several lying around so it wasn't enough of a problem to call PSA about it.
If you order a MOE kit, make sure to put in the comment section on the order page, to make sure there is a lock washer included.
I ordered a 3 pack of DPMS LPK's and two were obviously, hugely defective. The third was OK, but had a terrible trigger. I only use Stag now.
Brand doesn't matter as long as you get a good kit. The thing is some brands are known for putting out better quality kits than others. So I guess brand does matter.
I did tons of research on LPK's because I'm am building my first AR right now and I went with Spike's enhanced LPK $149.00 This LPK has received nothing but great reviews and a lot of people have commented that the 1 stage trigger in the enhanced kit feels better then other brand LPK's
LMT and Daniel Defense LPKs only for me.
I like Spikes and Doublestar and they have decent enough triggers. I haven't cared for DPMS and Bushmaster.
Just orderd a PSA lower build kit they had on sale. Will find out how it is.
I won't get into who supplies what, or how each vendor might source complete or machine their own stuff. So, Colt parts top notch, but they are expensive and not really put out as a LPK so to speak. I like LMT parts also. I do like kits branded DD and Armalite. There are also custom LPK put together by some dealers that use top notch parts also.
I found Stag Arms LPK's to be very good for me.
Over the years, I have used DPMS, Del-Ton, SARCO, RRA, DSA, and recently, Spikes. I can honestly sat thay I have had no issues with any of the kits I have used. These results are not always typical. Are all LPKs the same? In theory, yes. In actuality, not really. It is pretty much a trial and error test over time.
DD used to make palmetto, and they were great when I bought one a year ago, so I have been using DD lately.
I have used a RRA and it was fine.
I got a DPMS and then decided it was only good for a .22.
The springs are cheap, like they came out of a chinese pen. It seems like the trigger pieces are cheaper as well. I'm leaving them alone.
I'm sure LMT, COLT, KAC etc make good parts, but I've not used them.
