lower parts kits

[bmodzelewski]

are some lower parts kits better than others?

i'd like to build a nice premium lower with an engage armament lower and was just wondering if some parts kits are better than others?

right now i have a psa lpk.

thanks in advance.

Thanks for starting this thread. I, too, am interested in the differences of LPK's and if there are some good buys out there.

I'd love to buy high quality parts like a Geissele trigger, but I don't have that kinda cash for this project. I'm looking for high quality, but at a good price. Great value.

Thanks.

I've used one PSA lpk and and a few CMMG lpk's; both were good to go for me. I did stone the trigger and hammer to smooth them up abit. One thing I liked about the CMMG Kit's are the different parts groups are in different colored bags: for me that makes it easier not to mix the springs up.

Here....You can thank me later. I promise you that you will not find a better trigger for less than $100 let alone less than $50. The ALG QMS trigger is very nice for only costing $45. At the price of the LPK I am linking, you are pretty much getting the rest of the parts for $20.

To answer your question. Besides the trigger, all of the parts are pretty much the same no matter who manufactured them.

Just installed one of these in an Engage lower this evening (my first attempt at an AR build). Other than minor scratches getting the bolt catch roll pin installed, it went very smoothly. The install of that QMS trigger was cake with the slave pin!

I talked to a friend about this same things since I am in ur position with an EA lower. He said unless you get really shitty parts nothing should break. He said to get mil-spec parts. The higher end parts are usually made of Nickel-Boron which is a self lubricating material. I cant go into too much detail since i am not a expert, but he suggested I'd get a lower kit from these guys. I trust his advice since he's built like 10 ARs.

One of the best deals I've ever seen. That trigger retails for $230 alone. Initially when I bought it I thought I'd need to change the grip, but surprisingly the GI grip in the palmetto kit is pretty nice. It's not that thin flimsy plastic like some other kits, it seems to be a thicker, more solid polymer. I have a billet lower so the trigger guard didn't matter to me, but you'll likely wanna change that.

FWIW, I have 4 rifles, all using PSA parts kits. They all do what they are supposed to. I think you'd be hard pressed to find a better deal on a parts kit that you can add an aftermarket trigger, grip, etc to.

I bought 2 of therefor my Engage lowers.....
Like he said best deal given the trigger alone is more than this whole kit. They will be put in the safe for future endeavors.

Don't get a DPMS kit. I've gotten two, neither went in smoothly. The RRA kits were excellent.

 

[armed ferret]

as far as the small parts, any of the "major-brand" kits will work fine. PSA, CMMG, DPMS, etc. etc.

fire control groups is where it can get iffy. if you just want a "stock" trigger set, i won't be much help. I have ALG in both of my working rifles; wife has a DPMS and while the ALG's are much nicer, hers works fine. The SPR is likely going to a Geissele, as is the SBR billet lower.

Ive used both Spikes and PSA. No issues.

 

[ktigerJ]

Spikes and CMMG kits used. If you can wait/find a Spikes Enhanced kit and then get me one too.....

 

[Ooops]

I typically roll with Spike's. As Armed Ferret implied, for guns that are intended for precision, a higher quality trigger is preferred. I would look to Geissele.

I've used Spikes and PSA. The PSA kit was much nicer (although the Spikes kit hasn't given me any problems) IMO, YMMV.

 

[BradMacc82]

Aside from the triggers themselves, a LPK is a LPK to me. That said, I typically use PSA (cost-effective) and a few other makers since they're known to me as being g2g.

PSA
CMMC
Stag
and a few others that don't jump to mind right now.

Picked up a spikes enhanced the other day, can't wait to install on my PSA liberty lower. http://www.gamaliel.com/SpikesTactical/Spikes_Tactical_Lower_Parts_Kit_Enhanced_Black.asp

Wow. $67.99.. I just ordered 3.. great find.. thx

have a QMS in my M4 build and (currently) an ACT in my SPR (will be replacing with a Geissele eventually). Love 'em both. When I get the g-man upgrade for the SPR, the ACT may end up in the M4 and the QMS on the classifieds.

honestly, there is no better trigger for the AR in the price range than the QMS and ACT. ACT is of course a bit nicer, but it's also 20 bucks more, so if you're on a shoestring, go with the QMS and maybe do a bit of stoning on the mating surfaces if nothing else.
