Kaw Valley Precision AR-15 Gas Block Dimpling Jig Review

First Impressions of Kaw Valley Precision AR-15 Gas Block Dimpling Jig

The Kaw Valley Precision AR-15 Gas Block Dimpling Jig promises to be a solution for every AR builder’s gas block alignment woes. No more guessing, no more struggling – just precise dimples for secure gas block installation. Kaw Valley Precision has built a reputation for quality AR parts, and this jig looked like it would fit right in.

I’ve always been a firm believer in doing things right, and gas block installation is no exception. In the past, I’ve wrestled with gas blocks, often relying on visual alignment and hoping for the best, a method that has led to frustrating malfunctions at the range. I needed a way to consistently and accurately dimple barrels for perfect gas block alignment.

My first impression upon unboxing was positive: the jig felt solid, well-machined, and the QPQ finish gave it a professional look. Its compact design suggests ease of storage and handling. Unlike some universal jigs I’ve seen, this one seems purpose-built for AR-15 barrels.

I considered a few other options, including a DIY approach with drill presses and homemade guides. However, the potential for error and the time investment made the Kaw Valley Precision jig an attractive option. I also looked at some competing jigs, but Kaw Valley Precision’s reputation for quality and the multiple spacing options swayed my decision.

My initial reaction was one of cautious optimism. I was excited to finally have a reliable method for dimpling barrels, but also a little skeptical about whether it would truly live up to its claims. I hoped it would save me time and frustration, and contribute to increased accuracy and reliability of my builds.

Real-World Testing: Putting Kaw Valley Precision AR-15 Gas Block Dimpling Jig to the Test

First Use Experience

I tested the Kaw Valley Precision AR-15 Gas Block Dimpling Jig in my home workshop, which is equipped with a sturdy bench vise. I used it on a new 16-inch barrel for a mid-length AR build. The workshop environment is generally clean and dry, but I did test the jig’s tolerance to some gun oil residue.

The jig performed well, even with a bit of oil present. The barrel fit snugly into the jig, and the set screws held it firmly in place. The different spacing options were easy to select, thanks to the clear laser markings.

The jig was intuitive to use, and a quick watch of an online video confirmed I was using the correct procedure. I did have to make sure the jig was perfectly square in the vise, and that the barrel was seated all the way in. After that, the dimples came out perfectly aligned.

After the first use, I noticed a slight wear mark on the inside of the jig, but nothing that seemed to affect its functionality. The QPQ finish held up well to the use of a drill and gun oil. I did notice I needed to get a dedicated set of drill bits.

Extended Use & Reliability

After using the Kaw Valley Precision AR-15 Gas Block Dimpling Jig on several builds over the past few months, I can confidently say it has held up well. It has become an essential tool in my workshop. The jig has seen use on barrels of different profiles and manufacturers, and the alignment remains consistent.

The only sign of wear is some minor scratching on the surface, but the jig itself remains structurally sound. I have been careful to clean the jig after each use, removing any metal shavings or oil residue. A quick wipe down with a cloth and some gun oil is all it takes.

Compared to my previous experiences of manually aligning gas blocks, the Kaw Valley Precision jig is a game-changer. I no longer have to worry about gas leaks or misalignment issues. The jig has significantly improved the speed and accuracy of my AR builds.
