80 Lower Spotlight: Black .308 80% Lower Billet Fire/Safe Engraved

Router Jig Extreme Multi Platform by Modulus Arms (AR-15 / AR-9 / LR-308) with Premium Black 80% Lower Billet Fire/Safe Engraved (5-pack)

Most avid shooters have an opinion regarding everything in the pew universe. Unfortunately for the average or novice, this leads to conflicting “experts” telling them what is best for them.

Here at AR-15 Lower Receivers, we too have opinions but we believe all of them are subordinate to the individual shooter making a decision about what’s right for him. Some will tell you the only way to go is 5.56 while others will swear the .308 is the second coming.

Truthfully, they are both excellent loads and it really does boil down to preference. So if you have fought your way through every gun forum to get here to the Black .308 80% Lower Billet Fire/Safe Engraved options we are not going to fight your on it. You know what you are doing and it’s an excellent choice.

So let’s take a closer look at that beautiful 80 lower specimen and let you know what you are getting here.

Welcome to the 80 Percent Lower Universe

I’m assuming most of you who found your way here know well the aspects of the 80 lower. But lest some new guy orders the product only to find out he can’t fit the trigger housing group in because it’s full of aluminum let’s cover that real fast.

An 80% lower is the lower receiver of an AR that is, wait for it, 80 percent complete. That’s right, it’s all in the name. So if you missed that and you don’t happen to have one of our quality American made jigs on you, then we suggest you just throw the 80 lower at your enemy because it is otherwise useless.

However, the 80 lower being useless is precisely the point. Until the milling process is completed on the part, the 80 lower can’t be considered a firearm by the ATF. It might as well be an oddly shaped door stop as far as they are concerned.

This means you can have them shipped right to your front door and you don’t need an FFL to do so. In fact, because the gun laws are getting more and more aggressive these days we actually recommend you buy your 80 percent lowers in bulk and just save them for a day when you need them most. So if you are new to this concept, trust when we say this is the most liberty inducing piece of aluminum on the planet right now.

The Specs of the Black .308 80% Lower

Getting back to the actual product and a few of the gritty details, this lower is engineered to fire the .308 round when complete. Many like the .308 for its knock down power and whether you are fighting the zombie apocalypse or simple sitting in a deer stand looking to give Bambi something to cry about, this round delivers. This 80 lower is manufactured from billet aluminum. You’ll also see forged aluminum 80 percent lowers, but trust us when we say you can’t go wrong either way. It just refers to the process and billet aluminum starts from a large block and is rolled into a certain shape and then cut with a CNI machine. Techy stuff, but they are all good.

It’s made from 6061 aluminum and while 7075 is a bit stronger, the 6061 holds up without exception. It has the fire/safe engravings because despite how much you know about firearm safety there is at least one yahoo on the range who doesn’t know how to keep his booger hook off the bang switch. You can get an 80 lower without the fire/safe engravings if you so choose. Finally, it comes in anodized black and is 100% milspec.

So there you have it, the beautiful and simple Black .308 80% Lower. All of our products are fully guaranteed, because let’s face it, who wouldn’t guarantee a huge hunk of aluminum. We don’t hassle on the return process and all of our products are 100% American made!  Don’t forget to check out the rest of what we have to offer at AR-15LowerReceivers.com and start living this pew life the way it was meant to be lived.
