AR15.site is probably the best entry level AR15 gun store out there right now. That is because their prices are competitively low and their quality is enough for anyone to build a decent AR build out of. They have a pretty decent  assortment of AR build kits for people. Pistols and rifles on a couple different platforms. Their AR-9 kits are especially low priced, but I have only bought a couple of AR pistols for my wife and I. The lowers are of great quality, and the internals are mil spec so it is a very good base point, in my opinion, for those who want to get started with building. Its been hard to find a decently priced company with the pandemic spiraling the gun industry into absolute mayhem for the past year, which is why I am surprised by how inexpensive the company actually is. . AR15.site should definitely be a first look for first time 80% lower AR-15 buyers.
