Product description

This 100% made in the United States of America AR15 parts kit comes with all of the parts required to assemble your lower receiver except for the buffer tube assembly and stock.

This kit features an all investment cast trigger group, so you don't have to worry about a MiMed hammer breaking on you. 

All the little details are hit, including an Allen Screw instead of the standard flathead, so its easier to install the grip; and fully polished trigger and hammer connection points.

We purchased these kits by the truckload as part of a massive inventory reduction from a name brand supplier. Because we bought every single one of these they had on hand, they gave us an amazing price, which we are passing on to you. Part of our agreement in the purchase is that we cannot release the name of that supplier because they do not want us to devalue their product by selling these at the price we have them at.

This is one of those deals that once they are gone they are gone. We will not be able to purchase more American Made quality parts kits at the price we got these at again.

Pro Tip: To upgrade this parts kit for an AR10, Purchase our LR308 upgrade kit:

First, let me say that I hate, hate, HATE having to leave such a low-star review of this product. I mean, I want to love it, I really do because this is an unbeatable price for a LPK. However, I have issues with the trigger group that was sent. I noticed that it was ground smooth (a plus there), and damn near polished, but the problem is apparent once I reassembled the trigger group and did a test fire. The trigger drags and grates SO much that it feels like I have a two-stage trigger installed, instead of a regular one. This is fine if I'm slow-pulling the trigger but when I attempt to fast pull, it is not smooth at all and I can feel it dragging before it breaks. I don't know if I got a bad one out of the batch or what, but unless this is intended as a two-stage trigger in the first place, this is unacceptable.

Look, that said, this is a great LPK for the price, and it might just be issues on my end with getting a bad part or two, it happens. If you're in the market for a cheap LPK, this can't be beat, just beware that you might get a funky trigger like I did.

Response from Firearms Unknown:
Please send in a support ticket and we can replace the part you are having trouble with. Sorry for the issues there.

You deafly can’t beat it for the price I got one and I am purchasing another one well worth the $29 like some other reviewer’s said it’s just as good as the more expensive one Thank you

Thank you so much for the rapid fulfillment & shipping of my order! Excellent work! I was surprised to receive my items so quickly. Also, thank you so very much for the included mini book titled ‘The Constitution Of The United States’. It’s been a while since I’ve read up to refresh my memory of what our constitutional rights actually are. I plan to sit down tonight and read through this handy free inclusion you’ve so graciously provided with my order. Thank you. If you would like to send me links to your online social media or review websites, I’d be very pleased to leave you multiple positive reviews. Great pricing, super fast fulfillment & shipping, and a very patriotic & useful free inclusion with my order... simply superb! Keep up the outstanding work guys! Feel free to utilize my above comments for marketing purposes if you’d like. You have my full permission to include my name along with my comments as well.

This parts kit is the parts kit to end all other parts kits. The only problem with this kit is that I feel stupid for buying so many other ones in the past. I’m putting this in a poverty pony lower but I feel like in order to do it justice it belongs in something a lot more Gucci. Buy with confidence, real deal here.
