Dead Air Shim Kit — 3/4×24
Three shim thicknesses let you precisely time 3/4×24 muzzle devices. Always place the thickest shim on the barrel shoulder first.
- One notch (Qty 4) — 0.004" thick, ~35° rotation (~1/10 turn)
- Two notches (Qty 5) — 0.006" thick, ~52° rotation (~1/7 turn)
- No notch (Qty 1) — 0.060" thick, ~1.44 turns
Notes
- For 3/4×24 threaded barrels/muzzle devices
- Use combinations to achieve exact timing
