1911 Frame

1911 Frame

We’re excited to introduce the all-new 1911 80% frame! These 80% frames are 100% legal to own and are not legally considered firearms under ATF policy or federal law. You don’t have to deal with an FFL transfer for your online purchase, you don't need to file any paperwork, submit to a needless background check, suffer a waiting period for pick-up, or pay extra taxes and fees.

First time building a 1911? Here’s an instructional guide on how to do it.

Upgraded Aluminum (No More Steel)

Each 1911 frame blank is CNC machined from mil-spec forged 7075-T6 aluminum. This is a huge improvement to the 1911’s original steel design. Each frame weighs approximately 60% less than the 1911's original frame and each is 100% compatible with all retail parts of the same caliber. The result is a frame that’s ready for better performance and easy customization. All you need to do is complete some basic machine work with hand tools at home.

Build at home, No Experience Necessary

Our frames and jigs are so easy to use, even novice builders and first-time owners can complete a frame blank at home in a single day. The entire process can take as little as 30 to 45 minutes. Our frames are proudly made in the USA by some of the country’s best gunsmiths. Frames are available in full size (5″) and Commander (4.25″) models chambered in good ole' .45 ACP or 9mm. Each frame features a mil-spec anodized black finish or raw billet finish.

Complete Build Kits Available

Want everything you need in one shipment? Grab a 1911 build kit and you’ll have every part you need to turn a box of springs, bolts and bits into a quality, top-tier 1911. One that competes with the best for pennies on the dollar. We even bundled our frames with the jig so you can get to building the second your box arrives at your front door!

AR9 80 Lowers




The all-new AR9 80% lower receiver is a proprietary design, specifically made to improve the aesthetic of your 9mm AR build while affording total compatibility with all factory and aftermarket Glock magazines! In partnership with Palmetto State Armory (PSA) we're excited to announce this new lower receiver blank works with all PSA and other 9mm AR upper receiver assemblies that accept the Hybrid G-9 9mm Bolt Carrier Group (BCG). Rather than spend more on a standard AR-15 lower and deal with a finnicky "box conversion", you can purpose-build an AR9 from the ground up.

AR9 Parts Compatibility

This AR9 80 lower works with mil-spec AR-15 lower parts kits and mil-spec buffer tubes and castle nuts. Build a PCC (pistol-caliber carbine) or AR9 pistol and enjoy a standard buttstock and pistol brace! The required 9mm Heavy Buffer -- designed to operate with blowback function and not a typical gas system -- fits inside the standard buffer and utilizes a regular AR-15 buffer spring.

This 80% lower also works with virtually all standard AR-15 jigs, too. Since it utilizes a regular LPK, the cutting and drilling steps required to fabricate this receiver blank are the same as an AR-15 80% lower. View all compatible jigs and tool kits here!

Billet (6061-T6) Aluminum Construction

These pistol receiver blanks are CNC machined from quality billet (6061-T6) aluminum. Lightweight, aesthetic, and tough as Hell, each receiver's designed to reliably handle rapid fire and the extra pressure generated by 9mm's blowback recoil and cycling functions. Coupled with the proper end mill bit and drill bits, fabricating your lower receiver for final assembly is easy and convenient. Each jig includes the required instructions.

Why Choose an 80% Lower For the AR9?

Picking an 80% lower receiver over a "retail" stripped lower affords some unique benefits and cost savings: You don't need to file and pay for a background check, nor do you need to deal with an FFL and the various transfer fees. Most AR9 receivers are not available in stores, requiring you to order and purchase online. Shipping a legal-firearm-by-definition incurs higher costs and insurance.

Legal Under Federal Law

Because an 80% frame isn't legally considered a firearm, it ships straight to your door! Along with the jig and tooling, you can get everything you need in one order and delivered promptly. The frame blank by itself is also typically less expensive than a retail frame.

State Laws May Vary

Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of 80% frames, firearm blanks, and other gun parts. Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.
