PSA or Del-Ton LPK for AR15?

Just wondering which of the two is better or if there really is a difference. I'm working on my second build, and my dad is wanting to do his first. We're both doing very budget minded builds.

What's your take on the two?

If I bought the Del-Ton, I could use a coupon code and save 10$, lol. Plus I always like ordering from Midway.

The guns are going to be rugged carry/truck guns. Mine will be open sighted and his will be with a fixed, low power scope. Both will be used as potential hunting rifles.

I'd go with PSA.

Their LPKs are sourced from LW Schneider.

We have a couple of Del-tons. Haven't even had a reason to regret that. They have been flawless shooters.

One thing to consider is that PSA currently offers two lower parts kits with trigger group upgrades for a pretty low price bump.

One includes the ALG Combat Trigger (ACT) trigger group for $69.99 (their Palmetto State Armory Classic ACT LPK). The ACT trigger group generally goes for $60-$65 all by itself.

Another is the Palmetto State Armory Classic QMS LPK set that includes the ALG Quality Mil-Spec (QMS) trigger group for $59.99 (it typically goes for about $45 by itself).

Both ALG Defense products are a step up from the typical generic trigger groups & the ACT set includes polished sear surfaces & "hardlube" coated components (nickel-boron & nickel teflon).

I replaced the generic trigger/hammer group in my DTI build with an ACT set (and a JPE yellow trigger spring) and was very happy with the improvement in trigger feel.

Thank you for telling me about the trigger offering from PSA, I hadn't considered that.

Would you suggest the ACT or QMS and why? I read the synopsis of the kits, but I really don't understand either of the two, lol.

Thanks!

Both types are constructed to meet mil-spec for conformation & geometry - they can interchange with other mil-spec components - but are tweaked for best function within that specification envelope. The final finishing done with the sear surfaces is intended to remove the "grittiness" often associated with standard mil-spec trigger groups without reducing component lifespan.

I went with the ACT primarily for the "hard lube" finish on the various components. It makes for an inherent reduction in friction even before adding lubricants to the mix and is purported to have both wear & corrosion resistance. I believe there is also some additional polishing of the sear surfaces to improve the smoothness of the pull and sharpness of the break. I thought the extra features were well worth the minor increase in price.

Note that these sets do not necessarily produce a reduction in trigger pull relative to generic mil-spec trigger groups. Trigger pull weights for both sets will fall somewhere in the standard mil-spec range of 5.5 - 9.5 lb, with the ACT sets typically being around 6 lb & the QMS around 6.5 lb. You won't see lower than that unless you go with reduced power springs for trigger and/or hammer, which would have the potential to reduce ignition reliability.

I've put together two lowers using PSA parts kits and the quality of both was excellent.

I don't think there is any appreciable difference between the two. I have squeezed Del-ton triggers and PSA triggers, and they both feel like a crappy factory trigger. I would go with whatever you can get the lowest price on. I went with PSA because I was already ordering my upper from them, and it was cheaper to combine shipping costs. Plus they had a good deal on the LPK with the FDE magpul stuff that matched the rest of my rifle.

I wish they had those ALG LPK's when I ordered back in April. Those look awesome.

+1.
I have a Del-Ton LPK and trigger in my plinking AR for much the same reason since I ordered a bunch of other stuff from Del-ton. I have since stoned mine and it is much smoother and lighter than stock, but it is still no competition trigger. Most competition triggers are between $100 and $200 and are much better, but that isn't worth it to me for a cheap plinking AR, just ones intended for more serious work.

Either kit is fine. Most of the springs/pins and other small parts aren't going to be measurably different no matter whose kit you buy. As someone stated earlier, all of the factory triggers will feel crappy, long and gritty if you're used to something better anyway.

The ALG group is a neat option, and I have no doubt of the quality as it's a semi-offshoot of Geissele (it's his wife's project as I understand it). It's still going to have a mil-spec pull weight, but you can always swap out some lighter trigger and hammer springs.

RRA 2 stage match is still a good buy for the money as well.

I can't speak for Del-Ton since I've never owned anything buy them.

BUT, I do have a PSA lower on my AR-15. Everything is nice about it. But, I did have to REALLY screw down tight my Magpul MOE grip. It had some back and forth play that drove me crazy. I mean I REALLY had to tighten that scew. I've never had any problems with my Spike's Tactical lowers.

I'll also say, since triggers have been mentioned, that Stag Arms has a fabulous lower parts kit. I really think Stag's LPK has the best mil-spec trigger I've ever seen.

I've used quite a few LPKs, not PSA though, and Del-Ton and DPMS were lower quality (roll pins, trigger/hammer and pins). I hear lots of good about PSA, you get a lot for the money. My only PSA purchase was their receiver extension/buffer kit which was high quality.

I agree with the above, Stag triggers tend to be good. Stag and Daniel Defense LPKs have nice milspec triggers.
