AR-15 Pistol Kit - .300 Blackout (8.5" Barrel & 9" M-Lok Handguard)

$899.99
SKU:
300BLK-8.5-9MLOK-PK

Description

.300 AAC Blackout is somewhat a picky caliber, but one thing is for certain, it loves shorter barrels.  Also, they work well with suppressors.  Not to mention they're just a hell of a lot of fun to shoot.  That's why we're bringing you this AR pistol build kit chambered in .300BLK.

So what's in this kit?  Well for starters, you get a prebuilt upper assembly made with an 8.5-inch barrel and a 9-inch lightweight MLOK handguard.  You also get a lower parts kit that comes with a polished trigger for a little smoother performance, a Magpul MOE grip and trigger guard, and SB Tactical's SBA3 adjustable pistol brace.  Finally you will need to purchase your choice of forged lower made of 7075 T6 aluminum, billet lower made of 6061 T6 aluminum, or no lower if you've already got this part worked out for yourself.

What’s Included

This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, lower parts kit, and buffer assembly with pistol brace. It does not include the component to make a firearm: A stripped lower receiver. Pair this rifle kit with an AR-15 80% lower receiver and AR-15 80% jig to fabricate a receiver, sold separately.
