300 Blackout has taken the AR-15 market by storm, and we’re excited to offer up tons of new barrels, 300 Blackout uppers, parts kits, and 80% lower receivers so you can build yours! But with so many different configurations available (suppressed or unsuppressed, supersonic or subsonic), is it easier to just buy a store-built rifle or pistol? We think not. Today’s we’re discussing why you should use an 80 lower receiver for your 300 Blackout build:
#1: An 80% Lower Lets You Tailor your 300 Blackout Build
See, a store-bought 300 Blackout will usually perform well in a “standard” AR-15 setup. That is, you could find a rifle designed for conventional unsuppressed shooting with a typical 16” barrel and 1:10 twist rate. But this largely excludes what 300 Blackout was meant to do: Perform at different distances with different loads.
Building your 300 Blackout with an 80% Lower means parting together your new build exactly how you want it: Pistol-length barrel with a low twist rate and pistol gas system for suppressed, close-quarters shooting, an SBR with a moderate twist rate that can handle suppressed and unsuppressed loads, or a full-length rifle with an accurate stainless barrel.
In any case, building your 300 Blackout (starting with that 80% lower) allows you to save some money by only buying the parts you need to accomplish your exact setup – and chances are, it’ll out-perform anything you can buy at the store unless you pay a premium at the counter for a purpose-built gun.
#2: Using an 80% Lower for Your 300 Blackout Saves Money
Buying a gun at the gun shop means paying local, state, and federal taxes, as well as a transfer fee and PICS check. When it’s all said and done you could end up paying far more than the advertised price. That’s not the case when you build an 80% Lower.
Building an 80% lower at home means you get to avoid all those taxes and fees. Fear not, this is not some unscrupulous thing – it is 100% legal to build a firearm at home, no paperwork required, as long as you’re building that weapon for yourself as a private citizen. The Bureau of Alcohol, Tobacco, and Firearms even spells it out quite clearly.
This means that you can order your 300 Blackout Build Kit with an 80% lower and jig, and it’ll ship straight to your front door. Once you receive your kit, you can get to building right away. Just be sure to check your local and state laws first (they may require you to submit documentation for a serial number before you build your lower).
#3: Building an 80% Lower is So Easy, Anyone Can Do It
Gunsmithing sounds like an advanced, complex, and expensive endeavor – trust us, it’s not. That’s why we’re here! Our 80% Lower and Jig Kits come with all the tools you need to machine your lower receiver at home. All you need is a basic hand router, like our Porter Cable router (a crowd favorite).
