AR 15 charging handles are really a dime a dozen. So when I run across something innovative, I have to try and review it. SinterCore is just the company doing that. They have introduced an ambidextrous charging handle called the "TripWire." It happens to be of the extended type with some cool features.
After receiving the TripWire, I had to look it over. The reason for this is because it does not have your standard style moving latch. Instead it has a 3D printed carbon filled nylon latch. But what makes it innovative? Well, the latch is on a hinged pin with a spring and the handle/handles do not move or pivot. So all that one has to do is pull straight back on the handle. No pulling a latch or lever to unlock it, the latch just unlocks itself. The rest of the handle is 7075-T6 aluminum and hard coat anodized with some grooves cut in for better grip.
One might wonder how reliable this design can be, I was. But as I have used the TripWire, I found it to hold shut just as well as any other charging handle. The handle does take a little more force at first to cycle the bolt. This is because you have to overcome the spring pressure holding the charging handle from moving. I also slammed my unloaded AR against the floor numerous times to see if I could get it to unlatch, I couldn't. And while doing this I could hear the bolt moving, so it passed my hold closed testing.
I really like the design of the TripWire. It is lightweight, quality machined, and even 3D printed. Plus there are very few moving parts. Sintercore also told me that if I wanted a lighter weight spring to unlatch the charging handle, they could send one out. I thought it was fine and don't want the chance of the lighter spring making it easier for the charging handle to come unlatched. If you are looking for something other than the standard AR15 charging handle, give the Tripwire a chance.
