8 Comments | 08/13/2022

I recently conducted a series of mechanical tests on the Taulman3D Glass Fiber Nylon. The goal was to understand how annealing effected the properties of the Nylon. I also tested how water absorption from the atmosphere effected the mechanical properties, and how soaking in oil and annealing can combat the effects of moisture. These results

Welcome back to Hoffman Tactical! Today, I’ll update you on upcoming products, and what’s been going on here at Hoffman Tactical. Obviously the big thing that has been going down is the situation surrounding the cease and desist letter I received from rare breed. I won’t say much about it here, as it’s not settled

A “Forced Reset” style trigger allows the operator of the firearm to pull the trigger faster. They are pretty cool, and completely legal. Recently I decided to design a 3D printed conversion kit that would allow a standard “Mil-Spec” trigger group to be converted to forced reset. The mode of operation is actually very simple,

You asked for it. And it has arrived. I released the V1.0 AR-9 Super Lower a few days ago. Here are the details. My goal for the project was to have a 9 MM lower that would work with Glock magazines, use as many standard AR-15 parts as possible, and feature a last round bolt

I’d like to let you know that V2.8 is out, though it’s not that exciting of a release. The primary improvement is that the support rib has been redesigned to allow the use of Bear Creak Armory slick side uppers. V2.7 had a small amount of interference between these oversized uppers and the rib, this

Commenting on the proposed ATF rule(s)

With the deadline looming only a few days away, time to comment on the two proposed rules that the ATF has published grows short. In the past comments from the public have been effective at deterring the ATF from enacting new antigun rules. And yes, that was a redundant statement. This time around the ATF

If you head over to the Downloads page you will find that V2.7 of the AR-15 Super Lower is now available. V2.7 is very similar to V2.6 with a few minor improvements. The more important ones are: The profile of the left side has been widened so that a three position selector switch can be
