About Our Lowers:

Our Gen. 1.5 version Billet Lower represents an update mainly in DFM, or Design For Manufacture, where we went back to the Gen. 1 design and reshaped it in a manner that made the machining process more efficient. For example, the Gen.1 Lower machining process used fifteen tools through nine operations to complete, whereas the Gen 1.5 version eliminates three tools and two operations to accomplish even more. Moving from smaller tools, which take more passes and move slower than the larger tools that are used more, cuts the overall machining time as well.

These little manufacturing “tips and secrets” are things that we have learned over the past 19-20 months of machining on our own. And since we have cut our overall manufacture time by 26%, we can pass cost savings on to our customers in a lower selling price. The cost of the Raw Aluminum hasn’t really changed at all since we started.

For the Gen. 1.5 version, we also wanted to keep several of our design features (Front Finger Grooves), plus add some additional features not present on our Gen.1 Lower (Take Down Pin Recesses on each side), and try to remove a little “excess weight” where we could.

If you could compare the two you would see that the the Front Finger Grooves are moved back slightly, and there is also a cosmetic change just in front of the Trigger Guard, plus the edge break on the mag well protrusions is twice that of the other edge breaks on the rest of the Lower. We’ve also decided to offer our Logo as an option. You can also choose to have the “FIRE-SAFE” engravings omitted if you prefer.

Availability / Shipping:

Because our 80% Lowers are generally in stock in 6061 in the Raw form (or can be Bead Blasted quickly), the Raw 6061 80% Lowers can ship within 1-4 days by USPS Priority Mail. But since we have to send Raw pieces out of house to be Anodized, those can take up to 7-10 days total to ship.  7075 material may take another 5 days for shipping because we don’t stock as much of that grade of material.  Shipping is set at $7 for one Part and $12 for 2 or more Parts… and Free for Orders over $199. Your credit card will not be charged until order ships.
