Let’s Dive into CMMG, Inc 1/16×1/4in Pin, Roll
Roll pins. They’re the unsung heroes of firearm assembly, often overlooked until one goes missing or gets bent during a crucial build. The CMMG, Inc 1/16×1/4in Pin, Roll might seem like a tiny, insignificant component, but its reliable performance can make or break a range day. Let’s see if this small piece holds up under scrutiny.
I stumbled upon the need for this particular size roll pin during a frustrating lower receiver build. A trigger guard pin decided to launch itself into the fourth dimension, leaving me with an incomplete rifle and a rapidly dwindling supply of patience. After checking my local parts bin, I realized I needed a replacement and opted for the CMMG part.
Upon receiving the CMMG, Inc 1/16×1/4in Pin, Roll, my initial impression was positive. The finish was clean, and the pin felt sturdy, showing no signs of bending or deformation. It looked like a standard roll pin, but sometimes, it’s the little things that matter when your building.
I’ve previously used generic roll pins from assorted hardware stores, and, frankly, they’ve been a mixed bag. Some were too soft, bending easily during installation, while others were too brittle and prone to snapping. I also considered a set of roll pins from Brownells, but opted for the CMMG part for its specific size and because I have had great experience with CMMG parts over the years.
My first impression was a cautious optimism. It’s just a roll pin, after all, but I was hoping this one would perform as advertised and save me from further build-related headaches.
