✔️ 20 Piece Steel Shims 1 Inch Id Size Variation 001 To 004
This pack of twenty barrel nut spacers helps shooters get a tight center alignment when sliding in a free float handguard on modern build projects. You pop these slim rings right between the receiver extension and the lock nut to zero out side play without guessing. They handle gas impingement and piston styles chambered in 223 Remington, 5.56 NATO, 6.8 SPC, and 300 Blackout nicely. Just double check your platform first since they will not work on bigger actions like 308 Winchester.

✅ Machined from tough 304 stainless steel that resists corrosion and wear
✅ Includes five each of point zero zero one through point zero zero four inch plates
✅ Comes clearly labeled in separate sleeves for fast size matching during builds
✅ Can stack multiple plates together to reach exact gap requirements safely
💡 Why does my rifle shoot sloppy groups after changing out the free float upper assembly?
Proper front end alignment completely changes shot consistency when working with modular rifle components. You can fix wobbly point of impact drops with these handy thin metal shims.
- Matching the barrel nut hole perfectly centers the rifled tube inside the lower receiver
- Changing the gap thickness removes side load pressure that pushes lead shots off axis
- Testing different spacer combinations lets you lock in zero drift quickly on the range
- Using stacked stainless washers keeps tension even across the gas block area
