.300 Blackout Freedom Build Kit with AR15 80% Lower

What do you do when you're looking at hunting or home defense options for your AR-15 , and you realize you need a heavier load with stopping power than the .223 or 5.56mm NATO rounds at closer to intermediate ranges?  What if the answer to that question requires a more custom job?  Simple:  you get an AR-15 chambered in .300 AAC Blackout, and you build the damned thing yourself.  Let us get you started.

The .300 AAC Blackout round (also referred to as .300BLK) is to the AR-15 what the .45acp caliber is to the handgun.  And the .300BLK cartridge is gaining popularity at wild rates.  It's a slower, heavier load, which makes it perfect for close-to-intermediate range rifle shooting.  Our .300 blackout kit is the perfect answer for anyone from beginner to certified armorer.  Mill and drill your lower receiver, install your lower parts kit, attach the .300BLK upper assembly, and you're good to go.  That's it.  All you'll have left to do is supply the mags and ammo and mount the backup sights or optic of your choice.

With your upper assembly, you get a mil-spec lower parts kit, a six-position buttstock and carbine buffer system and a quality 80% lower, everything needed to finish your at-home build! This kit is 100% legal to ship straight to your front door, no FFL transfer or paperwork needed. Nothing in this kit is considered a firearm by any state or federal law. If you're looking for the most affordable way to build a quality AR-platformed rifle with a little more punch, we've got your six.

AR-15 Rifle Kit Details (Expanded):

Upper Assembly: This upper receiver is Forged from 7075 - T6 aluminum and is hard coat anodized black for durability. Featuring M4 feed ramp cuts, these upper receivers are made in the USA.  The upper assembly comes to you pre-assembled and ready to go.  Simply mount it onto your completed lower assembly, and add the backup sights of your choice.  Since its barrel is chambered in .223 Wylde, it's made to accept both .223 and 5.56mm NATO rounds.

80% Lower Receiver: This kit comes with your choice of either a forged or a billet fire and safe-engraved black 80% lower. Alternatively, choose the "No lower" option if you already have your lower picked out.  Our lower receivers are already anodized to match the upper receiver assembly perfectly. The 80% lower is ready for you to mill the trigger pocket and drill the holes for the trigger pins and safety selector.

Please note: This AR-15 build kit requires that the builder complete the 80% lower receiver themselves, but that's the rewarding part of the experience (and the only way to build your own AR-15 without the need of an FFL transfer or serialization).
