Most Helpful Positive Review Must have if your barrel is not dimpled
Made a mistake watching youtube and attempting dimpling without the jig. My advise - don't. You have a significant chance of ruining a barrel. if you have a sacrificial barrel - go ahead and try it without a jig. Otherwise use the jig.
Most Helpful Negative Review Paper shredder
Total piece of junk. Will destroy a barrel don't waste your money buy the one kak makes it works like a quality smithing tool should. First of all i nicked my finger on a burr so looking inside i saw a lot of burrs i pushed a paper towel thru the center and it shred the paper like shredded lettuce. ...

Seems Good

by Jim, Verified Owner from NY, United States Written on July 30, 2025
Seems like it'll work well but I have a longer gas block to cover the slots in the barrel from an A2 sight and this doesn't have the screw spacing to match (too short). Should've checked first.

Works well

by NastyNate, Verified Owner from CO, United States Written on January 22, 2025
The jig fit very well and made it really easy to dimple the barrel. I do wish it came with its own drill bit, but that’s a bit nit picky.

Absolute MUST for an AR build - don't approach your bench without it!

by Dave, Verified Owner from KY, United States Written on November 6, 2024
Other reviewers said it well, this is a must-have for building and is really easy to setup and use but there are no instructions. It is pretty straightforward on how to use but I'm sure there are videos on the internet in case you need them. Please note that one size does not fit all. Different barrels have different journal sizes so if you are building for different AR platforms (i.e., AR10 vs AR15), be prepared to buy multiple jigs. I highly recommend this tool!!!
Pros:
  • Simple & easy installation
Cons:
  • None
Best Used for:
  • AR Rifles and Pistols
Would recommend: Yes

Great product

by Jeff Y, Verified Owner from AZ, United States Written on November 2, 2024
The SLR dimpling jig is a great tool. I used it to dimple my fancy BA barrel. The jug is super easy and intuitive to use, particularly with the set screw that positions the jig exactly over the gas port. The channel screw on the opposite side perfectly positions the drill bit for making the dimple. The process took maybe two minutes. I will not dimple another barrel without the SLR jig now.
Pros:
  • easy to use
  • Intuitive
  • High Quality Machining
Cons:
  • Needs more vise flats
Best Used for:
  • Barrel dimpling
Would recommend: Yes

SLR Dimple Jig

by brooTool, Verified Owner from TX, United States Written on August 14, 2024
Worked great! I highly recommend to all who are wanting to professionally dimple and more reliably install a gas block that is not pinned to the barrel. Remember to use rocksett preferably or red locktite on the gas block set screws when installing. Also, i used a Milwaukee cobalt “hard steel drill bit” that cut my stainless steel barrel with easy and left perfect dimples.
Pros:
  • easy to use
  • well made and will last a life time
  • multiple set screw measurments
Cons:
  • None
Best Used for:
  • adjustable gas block
Would recommend: Yes

Pros:
  • Easy to use, Well made, accurate
Cons:
  • None
Would recommend: Yes

Great Jigs

by Gbenz, Verified Owner from TX, United States Written on July 21, 2024
I purchased a jig in each size available. They are great. They are spot on. The allen screw has a nice point that fits right into the gas hole in the barrel. The other allen screw on the other side is a perfect guide for the drill bit to dimple the barrel. It can be hard to see the dimple while you are drilling because of how thick the jigs are. Just take care not to drill too deep when you are only trying to dimple.
Pros:
  • Thick and good quality
  • Ease Of Use
  • Alignment was great and rock solid.
Cons:
  • Thickness
Best Used for:
  • Dimpling barrels for proper gas block alignment.
Would recommend: Yes

Awesome product

by Slapps, Verified Owner from TX, United States Written on July 17, 2024
This is my second one of these in different sizes. Works excellent. Pro tip only Dimple opposite of the gas port. That way if you ever have to change gas blocks, you don’t have a second dimple for something that may not match.
Pros:
  • Accurate
  • Very easy to use
Cons:
  • None
Would recommend: Yes
