The Last Of the Old Lowers
I made several versions of the finale angled lower design. Some of these even had a rib on both sides to fit slab sided uppers. Bushing pockets where also used to allow metal reinforcement.
End of an Era
The days of the easy printing angled lowers where at an end.
The First Super Lower
A Giant Leap Forward. I decided that my designs needed a make over. Starting from scratch I rethought the entire lower design and the result was the Super Lower. It included all of the older improvements such as the hose clamp, front pin plates and build in support. The big change from older lowers was the print orientation. Rather then the old forty five degree angle I opted for a ten degree print angle with the base of the mag well resting on the bed. This made supporting the lower during printing a challenge. Much refinement was necessary to minimize..Read More
Super Lower V2.5
V2.5 was a much improved version of the V2.4 AR-15 Super Lower. A flared mag well, more streamlined design and improved fit made it much better. Another important change was made with V2.5. The front take down pin was mirrored so as to match the rear take down pin.
LR-308 Lower Is Tested
After the success of the first Super Lower I decided to scale it up to an LR-308 lower. This became the first reliable 3D printable LR-308 lower.
3D Printable Stocks and Grips
One of my goals with the Super Lower is to provide a comprehensive lower package. And this should include the furniture needed to complete the rifle. Why buy a stock when you can print a much better one? That was my thought when I designed the stocks and pistol grips.
V2.6 and V2.7 Super Lower
These version came with better support and overhangs. As well as refined fit. The LR-308 Lower was also refined to match the AR-15 lowers.
V2.8
While V2.8 was a rather minor update, one important change was made. The support rib was redesigned to eliminate interference issues with the popular Bear Creek Arsenal uppers.
Gen 2 Stocks Are Released
The original stock design worked quite well. But had it’s limitations. The Gen 2 Stock System is more modular and even has the option for a TPU butt pad.
V3.0 Super AR-15 Lower
Besides the normal refinements to the fit and finish of the lower. V3.0 boasts a redesigned right side. Resembling the right side of the later forty five degree lowers, V3.0 has a much stronger neck then the older Super Lowers did. V3.0 is currently the recommend version of the Super Lower.
