Their main focus is on AR-15 and AR-10 platforms, so you are guaranteed to get Rainier Arms expertise on each product.
Rainier Arms stripped lower receiver is beautifully crafted. Starting with the markings, the left side boasts the Rainier Arms logo, and all the licensing cleanly etched. The fire selector uses safe, fire, and safe icons instead of the lettering, which is preferred by many. The mag well is also flared a little wider than the standard bevel, making it easier for fast reloads.
On the right side, the same fire selector icons are present, as well as the multi-caliber markings and the serial number. The right side also sports the Rainier Arms brand name. In addition, the front of the mag well also has the Rainier Arms logo. As for the trigger guard, the space is left empty for your own after-market installation.

- Respected brand name.

Why it is suggested:
Built from 7075 T6 aluminium, this lower is forged rather than milled, unlike a number of other lowers on the market. Forged lowers are stronger and take a beating without issue. These flowers are also hand-finished before being anodized.
New to the market is Seekins Precision. Founded in 2005, they specialized in Computer Numerical Control machining, better known as CNC. They provide competition-grade products and are renowned for their quality products.
Although the SP223 comes as a set, our review will focus on the lower receiver rather than the upper.

PSA has many offerings for its lower receiver market. From stripped to stealth and even fully modified. One thing that is for sure is that all products are made with the same precision that guarantees lifetime use.
The PSA AR-15 stripped lower is identical to the stealth lower. The only difference lies in the markings. On the left side, you’ll have the PSA logo, and the model number etched onto the mag well. The manufacturer and the serial number are right behind the bolt release, and the selector markings are safe and fire.

- Not the best looking lower on the market.
Why it is suggested:
There are very few companies that use 6061 aluminium for their lowers, and PSA manufactures all their parts with 7074 T6 aluminium. The lower features a black hard-coat anodized finish is mil-spec and is compatible with all after-market products.
Sharps Bros brings you impressive flowers that will stand out on the range. If you’re bored of standard, traditional lowers, try the Sharps Bro Warthog; it will definitely fit your brief for a custom AR-15.

Things to consider before buying best AR-15 lower receivers:
One of the biggest mistakes I’ve seen new builders make is thinking all 80 lowers are equal. The use of polymer in the AR lower build market is rising. Polymer lowers aren’t strong enough just yet to be reliable. They break rather easily and very few works well for long periods of time. We recommend using 6061 aluminium to start because it’s nice and strong.
7075 is the strongest aluminium to start with and will last the longest. For just a few dollars more, you can have an incredibly strong 7075 80 lower receiver that will basically last forever. The price difference between polymer and 7075 aerospace aluminium is on average about ten dollars.
