It gets the job done.

Used in an Aero lower. All parts work correctly but the safety selector action was very crunchy. Got a little better with some use but still less crisp and positive than my other ARs. Also, it's subjective but I don't love the grip. Its a very hard plastic and the logo embossed in it doesn't add much grip and looks like it's trying too hard to be cool. Still a good value for the money, but I'd try another one next time.
Will buy more

Very satisfied! I used it for my first build. Everything was individually wrapped per section and fit properly. Made my first build a breeze.
Installed easy as pie
by John -
I put this LPK in an Aero stripped receiver and all the pieces fit just fine. I dont know how well they will hold up in the long run, but installing them was no problem.
Spikes triggerless LPK.
by Jim -
Everything included except the trigger, which I have several laying around. Saved a few bucks there. Nice fit and function. Extra spring and detent included for that errant launch across the room. Not a perfect fit with the grip but that may be on the receiver end too.

This lpk is hit and miss. Some parts operate like a hot knife through butter while others are like sand in a transmission.
by Keith -
The kit I received was missing the bolt catch roll pin. I contacted PA for a replacement and they instead sent me a trigger guard roll pin. I guess neither Spike's nor PA can find and identify such a rare and unusual part.
Well Made Parts
by Tony -
Well made and machined parts. Fir perfectly into my Aeroprecision lower. Better quality than I have seen before in lower priced kits. I give it four stars because of the finish. Kind of sloppy and spotty. The worst part was the magazine catch which is about the most visible. Noticeably streaky and splotchy. I may be a little fussy but I want my build to look good. I had to carefully work it with very fine sandpaper and wool to at least get it even looking. On the plus side I didn't even want the grip that came with it. I had already purchased a Magpul. I ended up liking the Spikes grip better and used it instead. Overall though I'm glad I bought this kit.
Quite impressed! Excellent lower parts kit
by PaulS -
Quite impressed! Excellent lower parts kit, individually wrapped components (in groups) and greased. Quality is outstanding, all perfect fit and not abrasions or tool marks. All parts function flawlessly. The Grip is actually nice too as it has some spikes design work on it, ergonomics is nice as well.

Everything is nicer than I'm used to, even the roll pins, and mine included the billet mag release and the extra spring and detent. Grip is nothing fancy, but it's lightweight, so I'll probably use it for my future sub-5 lb challenge project. Excellent quality all around, and the takedown pins function very smoothly. I'll never get a budget LPK again!
Fast shipping & great prices!!!!

Super fast shipping, great price and great parts!!! I will be ordering much more from PA for my build.
I love Spike's Tactical!!! Got this kit for my Spike's Spartan stripped lower and it was a prefect fit!!! Primary Arms, you're AMAZING!!! thank you for everything!!
Meh. Could be better, but it is cheap!
Keeping in mind the price, it's not to shabby and will work. The grip doesn't fit flush to my Anderson lower, and honestly, looking now at the pitcure, mine is a bit different from what is displayed here. The saftely switch is a bit squishy. Not as positive as I would like. Tends to stop just before 'safe' and I have to flick it a little further.
higher quality parts than expected, they sent actual roll pins, a better a2 grip, and a better magazine release. will be my go to lower parts kit.
I have now purchased two of these from PA. All parts were there. Great quality with zero Issues.
Primary Arms sets the standard for excellence!!!

I cannot say enough great things about PA. If the customer service I get from PA was universal with all companies, commerce would be triple what it is and the world would be a better place. I ordered this kit and it was shipped the next day. Everything fits like a glove and PA is and always will be my Primary (pun intended) source for my AR parts. I will only look elsewhere if PA doesn't have it. For anyone that is brand new to the AR platform and this is your first buy or build, PA will answer any questions you may have without the ego that some guns shops have. They're here to help.
Great LPK. Billet mag button nice bonus. Extra spring for those who launch them to parts unknown. Have used several of these kits,and never disappointed.
Good LPK, good price.
by James -
All the correct parts were included, the finish on all of the parts was great, and everything went together as expected. They even included an extra takedown detent & spring for the inevitable "oops," which is a nice touch.
<br>One thing: instead of the bog-standard milspec grip shown in the picture, I got an upgraded grip with Spike's branding on it. I can't find it on their website so I don't know what kind of grip it is exactly. This was a nice surprise for me, but if you're absolutely dead-set on getting the standard A2 pistol grip shown in the product photo you might be disappointed.
Received the kit 2 days after ordering great customer service.
To be honest I just expected another lower parts kit like all the others. I was first surprised by the grip which is actually the new Spike's logo grip not the mil-spec grip in the picture. The parts were packaged in separate bags and were all solid. They included a couple extra springs just in case. Everything installed in a Spike's lower nice and tight and felt great. You also get the Spike's billet mag release button too. I will definitely get another for the next build.
Great Items and Pricing
by Fred (tnmarathoner)
Easy InstallPurchased this for my first AR build. Very pleased with items which included extra detent springs (in case you fling one across the room). Easy to install (see youtube and online instructions). All items fit well (tight) in PSA lower with ALG ACT trigger. Will order this again for next build. Primary Arms has good serice and fast shipping. Will order from them again in the future.
Missing Bolt Plunger
by Big Al
Just put together a lower and the kit was missing the bolt plunger. Luckily I had 2 kits and the other had one.
Spike's Tactical Lower Parts Kit (Without FC/Trigg
Excellent service, I returned this product and re-ordered a different one without any hassles.
I coupled this kit with the Spike's Battle Trigger. Everything fit very well with my Spikes lower. There was an extra detent and spring which is nice if you lose one while assembling the parts kit.
Excellent product, excellent pricing and fast shipping.The roll pins are stainless steel and go in nice.
