Under ATF’s 2022 frame or receiver rule, which the Supreme Court upheld in Bondi v. VanDerStok in March 2025, a receiver blank that hasn’t reached the point where it can be readily completed isn’t a firearm, so this lower ships without an FFL transfer under federal law. State and local laws vary; check our Shipping & Returns page before ordering.

Perfectly Polished for Performance

Th quality control is second to none and the finish show it: Inside you’ll find a disconnector, hammer hook, and sear that were laser-cut and polished to break as clean as glass at exactly 4.5 pounds. The trigger affords perfect reset after every pull, with no break-in required. Every roll pin presses easily, while the hammer and trigger pins glide in with little effort.
