This jig worked just like it was advertised. It couldn’t be easier to dimple the barrel for a gas block using this product.
Norman Holmes (verified owner) –
This is a great jig that covers all gas blocks with the different spacing between the set screw holes for your AR15. The price is fair and competitive.

For the first time dimpling… the KAW product worked very well and I was able to accomplish the task. The gas block buyer needs to know the spread of the set screws as precise measurement is not trivial

Great quality jig for dimpling the barrell so that the gas block stays firmly in place.

Repeatable results. Very well machined. Clearly marked for whatever the set screw spacing is for your particular gas block.
The flats make it easy to clamp in a vise on a drill press or mill, and it makes putting a proper dimple on the barrel a breeze.

Shipping was fast and the packaging was good. The jig is clearly marked for numerous gas port spacing specs. I was able to dimple my Daniel Defense barrel quickly and precise. The gas block set screw holes lined up perfectly. This product is definitely a must have to ensure professional results.

I used it the first day i received it , have done one Daniel Defense barrel , and one FN barrel , also used it to install an A2 sight without the pins. High quality product , does what it was designed to do.

Although I would have liked to have had a set of instructions for using the jig, I found a video on YouTube that showed the jig being used and it’s fairly straightforward. Definitely will be worth the money for each project going forward and not having to rely on a gunsmith for this type of job

Just like the .625 jig, would be great if it came with a bit. Trying to find 5/32 bit for this isn’t as easy as I thought. I would have been willing to spend a few more bucks for jig to be included at reasonable price.

Takes the doubt out of aligning and installing a gas block w/ setscrews. Great construction with many options for different size gas blocks.
Danielle Soncasie (verified owner) –
Great product and relatively quick shipping all things considered(covid). However I would have liked a tiny bit of instruction on proper drill bit size.

I ordered this on a Tuesday and received it two days later and this is with the “pandemic” craze.
Upon opening the well packaged box, I was greeted by a professional looking and well sealed bag with the dimpling jig (and two set screws) inside.
The finish is excellent and the markings are clear and concise. All of the holes are smoothly drilled and the threads on both of the set screws and the threaded holes are free of burs.
I highly recommend this jig. Thank you to KAW Valley Precision for making a simple, well made and affordable dimpling jig.

This is a high quality tool, very well packaged and lives up to the name Kaw Valley Precision. I bought the item because I bought a new barrel and it didnt come pre-dimpled. With this tool I will be confident that my gas block will be properly aligned and will not move once it has been installed. Excellent quality and great price point for a tool that can be used in the future should I choose to build another AR or change barrels once again.

I had ordered an off brand jig and wasn’t happy with it because it was completely round. Unable to clamp in the vise properly. I bought this one and it fits perfect! I was able to dimple my barrel and it worked flawlessly. Very happy with it.

I’ve used KAW Valley before and been so happy with their quality and customer service. I will always offer their products to my customers

I used this on barrel with blind faith it was made correctly…. Placed off positioned too far to the front by a little more than 1/32”. Buyer beware…. Not accurate.

It arrived a couple days before it was supposed too. That’s good, quick shipping.
The jig is great. I thought initially it was only 3 sizes but it has 6. It pretty easy to use.
The machining was a little rough. I screwed in the screws all the way through each screw hole. Some metal came out. When I used my first 5/32 drill no problems, I ended up having to use a Cobalt drill in 5/32 that was maybe a thousand of an inch bigger. I had to drill through the jig first.
I used a hand drill. I did what needed to be done but I would definitely recommend a drill press.
For $35 it is a great deal. If you are a garagesmith you will be fine.
