Reviews & Ratings for Tiger Rock AR-10 .308 5/8inx24 Thread Steel Crush Washer — 8 reviews — Page 1

Adding a muzzle brake required timing the device using a crush washer that is 5/8"x24 on a 6max rifle barrel. This Tiger Rock washer allowed for perfect timing of the brake. 6mm Max barrels use 30cal threads for muzzle devices.

Shipping and alerts were on point. I knew where my product was every step of the way. Works as expected and was perfect for timing my linear brake. 5 stars.

I needed a crush washer. I decided to buy two because why not. I was able to time my muzzle device as anticipated. The end.

I could feel the pounds per square inch of resistance increase with every degree of rotation. It felt smooth and calculated.

Installed on a DPMS AP4 308. This fit perfectly though the outer diameter is slightly smaller than the original, looks better than the original

Caught these on sale for $1 when I bought a new Yankee Hill Extended Flash Hider for my 300Blk. Always nice to have spares on hand so I bought a few.

Worked perfect on muzzle device install on a.30 cal build, compression was smooth

Nice fit if you need one that is a little fatter this is the one.

It works fine.. no issues.... fits fine...didn't have crush it.
