Barrel Shim Kit 5/8x24 Muzzle Brake Alignment 16 Pieces

I liked that it had several widths. With the right combination I used the least amount to clock a muzzle device.

this set was just what I needed to add an ASR muzzle device to my 300BLK and get the device clocked into the correct position.

This shim pack is well made and has enough shims to get your muzzle brake timed correctly. I miked several of them and they are dead on. Shipping was prompt and they arrived overnight

It took me like two minutes to sort these by simply weighing them. Two of each size. Since they are all the same diameter, the weight is in direct proportion to the thickness. Easy peezy. Of course, you'll need a sensitive balance to weigh them -- which you'll have if you reload. Then it took maybe one more minute to find the shim that got me to within a 1/4 turn of correct timing. With the crush washer installed I had plenty of range at almost the same 20-30 ft-lbs. Once I had it close, I used the torque wrench for the final alignment. Done. As others have said, these were a little larger than my barrel -- but not bigger than my muzzle device, so they worked fine. I docked one star for the size.

Great range of thicknesses. Consistent radial thickness, stated concentric to the bore when I used several to get the timing perfect. After thousands of rounds still nice and torqued, did not deform after final torque. Perfect solution, easy to order, can't figure out why LGS don't keep these in stock. No matter, easy peasy from Amazon in two days.

They worked good

If you're looking for an easier way to index your muzzle device so it threads on the muzzle in a particular way (say, putting an A2 flash hider on so the slots are on the top of the barrel, rather than the bottom), then using these shims are the way to go, as opposed to using a crush washer. These shims allow for closer engagement before locking down the device with a wrench, and I'm told are a better solution than a crush washer if you plan on using aftermarket silencers. Evidently, crush washers can distribute pressurized gasses unevenly, which isn't really an issue until you put a can on the other side of the muzzle. Don't go by me, but do your own research if you're interested.While I do like these better than crush washers, these aren't marked (mine weren't, anyway), so you'll need a few minutes of trial and error to get things like you'll like 'em. It took me a solid 15 minutes (don't laugh, I'm old) to find the right combo of shims to index my flash hider correctly, but once I did, I could torque it down without fear of overtorquing my crush washer and ruining it. Perfect fit for 1/2 x28 tpi muzzles. Plus, when you're done, you've got some spares. Recommended.
