Worth $49.95 Spikes is selling them for?

I just ordered a 10.5" Noveske light upper to drop onto a Spike's stripped lower I have (no SBRs in Michigan..she's gonna be a pistol). I have a grip leftover from a previous build and bought the pistol tube/buffer with the lower. So, no I just need an LPK to finish the build.

So, is the DPMS GTG, or should I buy something else? Mind you, this won't be a precision unit (I.E. no need for two-stage) just a plinker. But, I'll spend what I need to spend for quality. Thanks!!!!

I own several and they get the job done.  RRA LPK's are better IMO.

They are OK, But I wouldn't use the split pins that come with the DPMS kit as they are oversized and could contribute to trigger ear breakage.  
I'd get the coiled spring roll pins for the trigger guard and bolt catch.

RRA, Essential arms have them along with Grainger and MSC.

Why not just buy a pre-accurized LPK from Bill Springfield?

A nice, safe 4lbs trigger for $119. Then you won't have to send it him to later when you are dissatisfied, like I did.

I used to buy DPMS LPK's at Brownells for $44.00. Even at that price I was not impressed. Their roll pins are often oversived split pins. So i usually ended up using roll pins from RRA or Armalite with the rest of the DPMS components.  That said I like DPMS hammers enough that i use them in all my builds.

I've used a couple DPMS LPKs. The hammer/trigger pins like to walk, even when properly installed (replaced with KNS). The roll pins also were a bit obstinate when it comes to being installed.  I'd recommend spending the extra for RRA or similar quality kits. The RRA kit I used went in a lot easier than the DPMS.

I have used four sets, the pins are a little hard to work with, but I have had no issues. Each rifle has 23k, 5k 3k and 1k respectively.

Sometimes the roll pins are a pain, and the trigger and hammer pins could be better. Other than that they are fine.

I have no issues with DPMS LPK's.  Cakewalk to install.  An LPK is an LPK to me...

Not all parts are made the same DPMS has a much higher rate of failure than Colt, Stag/CMT and a few others.

Failure rate for what?  Springs?

I don't use the triggers, I don't use the grips or grip screws, I don't use the trigger guards.

The only failure I can think of would be springs and the bolt catch???

Bolt catches and magazine catches mostly. I've broke a couple of each.

I can understand breaking a bolt catch but what are you doing to break a magazine catch? Do you over install them?

Just flawed parts subjected to real use.

DPMS LPKs are definitely not GTG.

DPMS LPK's are GTG. I agree with the roll pin comments; a little tough to get started, but not overly difficult.

He's not exactly the only person on the planet to say that, ahem. And let's knock off of the Get The Fuck Out comments. Thanks.

I have drawn fire for this... but I will say it again:  I have used countless DPMS kits on many builds, mine and others.  Several, not all, of the builds have seen some "good steady use" due to LE quals, planned/systematic training, and carbine classes.  At least three have been used in a "steady use" environment.  All builds have been 100%.  All the rifles, factory DPMS and builds I learned had DPMS kits, that I have been around have all been 100%.

It's got to the point every time I meet someone with a DPMS rifle, or self-built rifle, I like to fins out what kit they used, if known.  If they say DPMS, I ask about rifle issues (LPK related) and to date, have found none.

IMO, DPMS LPK's are good to go.  If they were as flawed as many on this site post about, we would see broken parts on a regular basis... am I missing "regularly posted parts failure" posts?  If so, I will STFU.

As for the split pins, about the second time I used one, I USED A LITTLE COMMON SENSE and slightly pinched the roll pin.  Easy fit and guess what?  No pin has ever come out or backed out.

Are there better LPK's out there?  Perhaps.  But DPMS LPK's are not complete "airsoft junk" like some would have others believe.

$50 from spikes + $35 from bill is $34 cheaper...  ~$34 can get you a magpul trigger guard and more comfortable pistol grip
