Overall it was great. I loved the quality and style and ease of using parts. While I needed to drill deeper for trigger mechanism to work properly. He was great the only thing I had issues with was pin used to hammer into side of 80%. If I had to do it again. I would drill that hole just slightly bigger so pin would still fit snuggly with out marring finish on your lower. It was… read more not a good fit and either hole was too small or pin was too thick in width. Otherwise it was excellent and I will buy again. Thanks so much!

I have not assembled my lower using this kit yet but, I have looked at each part and it appears to be a pretty good kit. Just finding a lower build kit these days is tough, finding one that isn't junk is really hard. They even included an extra grip and a can coozie. Nice touch!
Excellent Kit, not so accurate takedown pins.

These kits are great. Very nice looking and perform great. Had a issue with the takedown pins, but when I contacted customer service they were quick to send me a new set out. I'd highly recommend ordering from this company. Really quick responses and very nice. Shipping times are great as well.

Great kit. Had some figment issues with the mag catch, it just needed a little touching up and de-burring with 1200 grit sandpaper and it did just fine.
Best bang for your buck

Overall kit is to spec. Took me about 30mins to assemble the lower and perform a function check with no issues. I did swap in reduced power springs so I can speak on the trigger, the pistol grip is large and tectured which fits my hand better which helped with my trigger pull. Only down side the buffer rattled but functioned as should.
Perfect

I’ll start off by explaining on how I got to ar15discounts website. I recently purchased a new upper and was looking to buy a complete lower kit. I saw many websites, but they weren’t complete kits or they were too expensive. Landed on ar15discounts website and saw this kit. Exactly what I was looking for and for a price I liked. Unfortunately they were sold out so I was on… read more the waiting list. I emailed them for an eta and Jennifer emailed me back in 10 min with a response. I was starting to like this website. 4 days later I got an email saying the items in the stock, so I quickly ordered, but forgot to add my promo code. I emailed them and 10 min later got a response that they’ll apply that promo code towards my purchase. Got the package 3 days later and I’m very happy with the kit. Verified that everything is there and came with an extra A2 grip along with couple extra springs. Thank you guys. You have gained a lifetime customer.

I've built many rifles in the past using expensive LPK so I figured I'll give this kit a try. I ordered it on Friday night and it was shipped the following day then I received it in 2 days. Now that's some quick services right there! I had to wait 4 months for my LaRue system so I know the pain of having to wait. The overall build quality is great. Is this kit comparable to BMC… read more or LaRue? NO and it shouldn't be because its a budget LPK after all. I would highly recommend this kit for people who are new to the AR platform and want to build a budget starter AR-15. You won't be disappointed for $70!!!
Ar lower build miss match
Jacob F.

I didn't like the miss match of colors with a brown butt stock and a black grip. I did like the soft grip so I used my extra butt stock from a previous build, I was still at budget for the build.
