AR-15 LOWER PARTS KIT Reviews & Ratings

Went together perfect. Everything feels good. Thanks for the extra detent spring definitely needed it.

Ive built myself 13 Ar15 rifles and 3 pistols. Ive used psa mostly and 1 RRA lpk. This trigger is awesome! Checked has 4 lb trigger pull.....that is the smoothest standard trigger Ive ever used. I got 2 of these hoping that the reviews were accurate. Well they are. Has NO creep crisp break and reset is actually very positive. All other single stage triggers are very gritty and sloppy with horrible reset. Actually had a few that werent even polished in the contact points to were it was a 8-9 lb pull. Very horrible. Got a Geissele and 2 RRA 2 stage triggers I think these single stage triggers by double star are a little better than RRA 2 stage. But Geissele still takes the gold medal. If youre reading my review, Dont hesitate on this LPK. Fantastic.

To start, I've got to say I was happy they packed an extra detent and spring for the pivot pin, this being my first build and my having inevitably launched them across the shop (I did find them later, so I've got extras now). That being said, I thought the safety was a little scratchy but that should go away with a little use. I bought this because almost everyone that reviewed this set was impressed by the trigger. I'm no AR expert, but I've done a lot of rifle shooting, mostly bolt action, so I'm spoiled. I've gotta say I couldn't believe it the first time I tried it. I used the trigger scale 10 times, and nothing was higher than 3lb 9oz and nothing lower than 3lb 7oz. Just a little creep prior to the break, but it broke nice and clean. That is light (and crisp) for this type of rifle and the repeatability was great. Don't know if I'll ever do another build, but if I do, I'll buy this again.

I installed this on a Stag lower and can not be happier. The parts are well built. I did not use the trigger guard, I used the Magpul trigger guard. The safety feels a lot better then the DPMS. It's a smoother transition from safe to fire. I have put this lower parts kit on several lowers I have built.

I was a bit anxious going into my first ever lower build. But thankfully this LPK installed into my Spikes lower like they were meant to go together. The parts are nice and oiled in the baggie which I am sure aided in installation. Also want to say that I really like the trigger. It is nice and crisp and has a very short take up. But we'll see how it really does when I get the upper together and some rounds down range.

The Kit was easy to install and the trigger is a pleasant surprise. My friend who has a timney trigger even raised his eye brows on the trigger pull. His trigger was still crisper but for a stock trigger this one is the way to go. My only complaint with the kit was it was missing the hammer/trigger pin. There are suppose to be two and only one was in the package. I didn't want to wait in the mail for one so I just picked on up at a local gunsmith. But I still feel this kit deserves all 5 stars.

I ordered the Doublestar LPK to go into my Stag Arms stripped lower, and the fit and finish of the parts is excellent, and went in with ease. Everything runs nice and tight, and the trigger has just a little bit of creep, which I like. I was also motivated to support local business by buying Doublestar. Overall I would definitely recommend this kit for anything needing a good solid parts kit for a great price. Certainly not a Geiselle Trigger Group, but I would easily recommend this kit. Doublestar even included an extra pin detent, because we all know how putting those things in can go.

Most of the parts went together almost too easily but the take-down pins are a bit tight in my lower. The trigger is amazing, total travel is about 3mm and there is very little if not zero over-travel. There is some creep but with the little distance the trigger moves it is not very noticeable at all. For a combat rifle the trigger would be perfect, for a bench rifle I think it would be pretty good... depending on how ridiculously picky you are. Overall it is very good now I need to see if it will withstand the test of time.

I have now built 8 ARs and used 3 different brands of lower receiver parts kits and let me tell you, after using this Double Star this will be the ONLY LPK I use ( unless it is a two stage or something like that ). This is the absolutely best I have used between DPMS, Rock River and one from another Co., I was so pleasently surprized with the quality of parts and the smooth, smooth action after installing the LPK.. you can't go wrong with this kit.

I got this parts kit and everything was great! Tolerances were tight, almost too tight. It took a hammer and alot of force to get the selector into the hole. Other than that, everything is great. I would rate this better than the DPMS part kits I have used.
