Paper shredder - SLR Dimpling Jig Gas Block

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. I needed the tool right away so i deburred it the best i could it now would go barrel without scratching it all to . BUT WAIT thats not all it doesn't line up right your dimples will be low left of center with their cheesy screw in drill guide . So once you have dimples in the wrong spot about your only fix is dimple in another spot with a DIFFERENT TOOL or cross pin which is probably better anyway. So i should have returned it to start with and save all the trouble and money but i didn't.
