Incredibly underweight - TRYBE Defense AR-15 Carbine Buffer & Spring Mil-Spec

This is not H1, H2, or H3. Despite it sharing the form factor, the weight is actually a carbine buffer stack. This thing weighed in at 2.8oz or so. Your gun will likely be INCREDIBLY overgassed if you run this. I had to buy this quick and cheap for someone else's standard AR and this thing was beating up cases and had crazy erratic ejection and could tell the gun was overgassed. Then I weighed this buffer and sure enough it's below even the most budget weight. I would NOT recommend you run this.
