This is a complete AR15 Pistol lower reciever including the PWS Enhanced Pistol Buffer Tube, and grip.

Built from a 7075 aluminum forging for superb strength & exact dimensions, this lower receiver is perfect for building a custom AR in the traditional .223/5.56mm chambering, or a special-purpose rifle in 6.5mm, 6.8mm, 9mm, or other caliber that fits a standard AR-15 receiver. Standard .154" holes for hammer and trigger pins let you install the aftermarket trigger of your choice; .250" pivot and takedown pin holes for compatibility with a broad range of upper receivers.

The PWS MK1 Receiver is considered a firearm and MUST be transferred through an FFL Dealer (a 10% credit card and processing fee WILL be applied for order cancellations.)
