Metallurgists agree that a forged piece of aluminum is stronger than cast or billet. The reason being, when the material is shaped under pressure, its ‘grain’ follows the same shape as the part. As a result, the product manufactured is stronger due to the continuous grain characteristics allowed by the forging process.

Is a billet lower better?

Billet lowers are usually substantially more money then forged lowers. The reason for this is in the manufacturing process, not the strength or quality of the end product. Remember a machined lower starts with an entire billet block larger than the end product.

Are billet receivers stronger?

Because most forged AR receivers are pretty much mil-spec, so if you want one with a unique shape you’ll probably have to go with billet construction. And the bottom line is, billet is plenty strong for an AR receiver.

Are billet lowers mil-spec?

Billet receivers are not considered to be Mil-Spec because the manufacturing process, materials and dimensions can vary from the military call-outs. Due to the added thickness and custom designs, some Mil-Spec style parts may have fitment issues.

Are Anderson lowers cast or forged?

Anderson Lowers are cheap ($42 for stripped and $120 for complete), they’re forged 7075-T6, and they’re often available.

What are AR15 lowers made of?

A forged AR15 lower is essentially a block of high grade aluminum that is super heated, and then hammered into the shape of a lower receiver. The forging process hammers the molecules of the aluminum together, thus making it incredibly strong.

Why is billet so expensive?

Speaking of cost, why are billet parts more expensive than cast? Primarily it has to do with scale. Machining one part from billet isn’t too expensive. The problem is that it doesn’t get cheaper per part to machine one hundred parts, or one thousand parts, because you can still only make one at a time.

What is forged billet?

A forged billet wheel begins as a solid piece of aluminum known as a billet. The billet aluminum is forged into a plate like form using extreme pressure and heat to form a raw forging, known as a rim center. The forgings are turned on a CNC lathe and machined on a CNC Mill to form the desired style of wheel.

Why is billet stronger than cast?

That’s because cast materials are heated and cooled more by the time they become a finished product which changes the structure of the metal itself. That’s why our billet aluminum housings are stronger than our cast aluminum housings.

Is billet better than cast?

Billet aluminum is generally considered a stronger material than cast. Billet parts are made from a single block of material that is machined down on a CNC mill. The result is a gorgeous part that can be made to match an engineer’s design with perfect precision. It also gives you perfect precision in design.

What is a forged lower?

What is the difference between a forged and a billet lower?

In conjunction, forged lowers are typically lighter (though marginally) due to their design differences and tolerances when compared to billet lowers. Forged lowers are also easy to find, as well as the most commonly sold style of lower. A finished (and anodized) 80% forged receiver.

Forged lowers are manufactured using a basic and older method of forming the rough shape of the receiver molds. Further hammering down the metal so the pieces combine really well on a molecular level. Forged lowers are comparatively a bit crude in appearance than billet receivers.

What is an 80% forged receiver?

A finished (and anodized) 80% forged receiver. As with any product, there is give and take when choosing a forged lower. Perhaps the most important, is tolerance. During the forging process, aluminum is displaced when subjected to heat and pressure. This displaced aluminum often creates imperfections in the lower, and will need to be taken off.

What is the best 80% lower on the market?

By far the most popular on the market, and winner of “Best 80% Lower” by PewPewTactical! Just like with forged lowers; billet lowers do have some draw backs. Billet lowers tend to be heavier due to the excess material left on for design or aesthetics, however the weight difference when compared to forged is minimal.
