American Defense Manufacturing Sig Echo 1 Base Review

Was the American Defense Manufacturing Sig Echo 1 Base the Right Choice?

The American Defense Manufacturing Sig Echo 1 Base is a quick-detach mount designed specifically for the SIG Echo 1 thermal optic. American Defense Manufacturing aims to provide a reliable and repeatable mounting solution. Its compatibility with both in-spec and out-of-spec rail systems thanks to its patented QD Auto Lock Lever system is a significant selling point.

I needed a solid mounting solution for my SIG Echo 1, one that wouldn’t lose zero after repeated removal and reattachment. I was looking for something more robust than the factory mount and trusted the American Defense Manufacturing name. The promise of a quick-detach lever and compatibility with potentially out-of-spec rails was very appealing.

Upon unboxing, the American Defense Manufacturing Sig Echo 1 Base felt solid and well-made. The hard coat anodized finish gave it a professional, durable feel. The QD lever clicked positively, and the machining appeared precise, suggesting tight tolerances.

I considered the Scalarworks LEAP/04 and the Midwest Industries QD mount for the SIG Romeo series as alternatives. I chose the American Defense Manufacturing Sig Echo 1 Base because of American Defense Manufacturing’s reputation for quality, its proven QD system, and the positive reviews regarding its ability to maintain zero. The price point was also attractive.

I was definitely excited to try it out. The initial impression was one of quality and confidence that it would solve my zeroing issues.

Real-World Testing: Putting American Defense Manufacturing Sig Echo 1 Base to the Test

First Use Experience

I tested the American Defense Manufacturing Sig Echo 1 Base at my local shooting range, mounting it on an AR-15 pistol. I spent the day zeroing the SIG Echo 1 and then removing and reattaching the optic multiple times. I wanted to simulate field conditions where the optic might need to be removed quickly.

The weather was dry and sunny, typical for a California day. The mount held zero remarkably well, even after repeated detachments. I did not notice any significant shift in point of impact.

The American Defense Manufacturing Sig Echo 1 Base was easy to use. The QD lever made installation and removal a breeze, requiring no tools. I did have to make a slight adjustment to the lever tension to ensure a snug fit on my specific rail, but this was easily done with my fingers.

Initially, I noticed a very slight loosening of the lever after about 20 detachments and reattachments. However, a quick tightening solved the problem, and it remained secure afterward.

Extended Use & Reliability

After several months of regular use, the American Defense Manufacturing Sig Echo 1 Base continues to perform admirably. It has been used on multiple AR platforms and retained its zero through several range sessions. It also survived a two-day hog hunt in Texas.

The American Defense Manufacturing Sig Echo 1 Base shows minimal signs of wear and tear. The anodized finish is holding up well, with only minor scratches from normal use. There is no evidence of corrosion.

Maintenance is simple: a quick wipe-down with a cloth after each range session keeps it clean and functioning properly. I occasionally apply a drop of oil to the QD lever mechanism.

Compared to my previous experiences with less expensive mounts, the American Defense Manufacturing Sig Echo 1 Base is a significant improvement. It offers superior repeatability and peace of mind knowing that my optic is securely mounted and will hold its zero.
