What's the difference between different brands of LPK?  Daniel defense LPK were $90 and PSA , Anderson's and damage industries were $50 bucks.  Spikes were $70.  What's the difference and  why a significant price discrepancy?  The ads does not say any special finish or a better trigger etc.  AIM has Anderson's LPK now for $50 shipped.  Are they good?

Some Will say the quality...but to me it's just a brand name

As long as everything fits and functions like it's suppose to I see no difference

Mil spec is mill spec pins are pins and springs are springs

You start getting differences in triggers tho..some might be more polished and less gritty but at the end of the day there all single stage triggers.

You could get a lpk without the fire control group and pick up a rra 2 stage or for more money a gieselle trigger but if you want a standard trigger then just get a lpk from where ever


I would stay away from ptac tho from psa. Get there brand lpk if you go that route

Buy a LPK without the fire control group, and add a ALG QMS trigger. $69 and it'll be great, available at Joeboboutfitters. ALG QMS add LPK without FCG

Mainly just a finish thing. I bought an AR15.com LPK and the trigger guard looked and felt better in the hand compared to my CMMG LPK. (it almost seemed like the cmmg was pot metal compared to the AR15.com one) Also I will say the trigger I got in the AR15.com LPK is AWESOME for being milspec. It has almost no grit to the trigger and it is pretty light as well compared to my CMMG. In the future I will only be purchasing AR15.com LPKs.

The Spikes kit has nicer roll pins IMO and are easier to install than other kits I have seen (PSA, DPMS, CMMG). Also came with a Seekins billet mag release button which was a nice bonus

Just ordered one of those today. Looking forward to getting in so I can start my next lower build.

Just to let you know when I ordered the ALG from Joebobs yesterday when you "add to cart" they give you an option to buy a Joebobs part kit without FCG for $24. I ordered it. Never used one before so I'm not sure of the quality. But for 24 bucks I figured it was worth a shot.

Well, let me tell you what I found out.
If your like me, you will read hundreds of reviews and hunt for good deals/shipping on your AR build parts.
I wanted an LPK w/o trigger group and I kept coming across relatively above average reviews on a JP LPK w/o trigger group.
So I ordered it along with other parts from a reputable retailer that we all have heard of and to my dismay when it arrived it came with no markings or brand name tags attached to indicate that it was in fact a JP product.
It was simply in a sealed clear bag (bag within a bag-heat sealed). Keep in mind that this retailer also sells a similar product for ten dollars less, of course listed as their name.
So I sit there and wonder what did I really get. I technically don't know. In the past I have ordered a CMMG kit and as we all know it comes a certain way packaged in separate bags in a CMMG box.
At least you feel you know what you have.
We are building weapons and making choices according to perception of the fact that a company such as JP would not sell below average quality. If we wanted no name parts, we would order them that way and save money.
After E-mailing the retailer, who responded quickly, he indicated that this is the way they receive it from JP and also indicated the different type of packaging that his other triggerless LPK's are packaged.
He described mine correctly and put me at ease somewhat in regards that I received a JP kit.
But of course my OCD kept kicking in and I reached out to JP.
They indicated that it was the correct packaging and that the reason for the no name packaging was that they do not put their name on a product that they did not manufacture.
Now the best part. After in depth research I found out that their LPK's are packaged that way directly from DPMS.
OK, so I have a DPMS LPK. Now, I am not saying that it is bad in anyway, I am just saying that I know where I feel DPMS is on the tier of manufacturers and I am pretty sure I probably would not have purchased it from them.
So you start to realize that this big AR platform of parts manufacturing such as LPK's, springs, lowers, uppers, barrels, buffers, buffer tubes etc.. are sourced from only a few MAIN sources and in the LPK world I think you will never figure out the original sources.
Anyway we are talking about LPK's and as mentioned before, it really is about 90% about the trigger, so in my case I am talking about springs, and a few mil-spec parts that are not as critical. I will realize problems during the build, mostly about fit and finish if any.

I bought a LPK with the ALG Defense ACT trigger group for $90. I believe I got it from Brownells but all of my records are at work. I will check tomorrow and update this ASAP.

I went with the LPK w/o trigger from PSA (on sale, of course) and Brownellls had the ALG QMS trigger on sale at the same time, so I lucked out.  I'm very satisified with the QMS trigger.  Very smooth and a clean break.  Probably not a benchrest quality pull, but for my purposes, it'll work just fine.  And I agree with the earlier mentioned assesment that there are most likely only a few mfg. of springs, pins, etc. in the country, so it's likely all the various kits have parts from the same sources.  Prices for these commodities (springs,pins, small parts) are quantity driven, so a wholesaler buying 10,000 pcs. is going to get a better price than one buying 1000 pcs.  In my opinion, some sellers think their name is worth the extra money, and there are those who think the more you pay, the better the quality.  I just don't happen to be one of them.

We've sold thousands and they work well. Thanks!

You received a JP LPK w/o Trigger Group. We do not typically carry DPMS lower parts kits, and have never carried their kits without fire control groups.

In the past, AFAIK, all of the DPMS lower parts kits came in clamshell packaging such as can be seen here:
http://www.ar15.com/archive/topic.html?b=7&f=125&t=1096880

You are correct in the fact that some of the packaging is minimal at best from many manufacturers on small AR parts. However, retailers such as us always keep them separate easily due to their distinct packaging differences. The parts are typically sold online and thus do not have very pretty or detailed retail POS packaging.

I'll tell you that I have moved away from any DPMS parts. The last LPK kit I bought was just horrible quality, the castings were real cheap and irregular and worst of all when it was together the safety was not positive at all and the trigger was horrible. I switched to CMMG and their LPK was superior in every respect, and every bit as good as any Colt part I have handled (and I've handled a bunch as an armorer), I built 6 with RRA kits a couple years ago that were pretty good too. I just bought the PSA weekend special that had the Magpul STR stock,moe grip, moe trigger guard , buffer tube kit and LPK for $149. I figured if it is crap I will still break even. Will report back when my 5.45 build is complete and running.

Just an update on this I just got finished installing the ALG QMS with the JB LPK in an Anderson lower. I am very pleased with the quality of the entire kit. The quality of the LPK was as good or better than the last two PSA's I've used, along with the ALG FCG all for $68.00 throw in a mag or two and you get free 2 day shipping . Can't  beat it IMO

I just built a lower with a CMMG kit, it went together easy and the stock trigger is much smother, shorter and crisper than other stock AR triggers I've played with.
