These are the length-of-pull spacers for the X-ray Chassis.
They can be used with the Whiskey-3 but will require the shooter to source different screws.
Each spacer is 3/8″.
The starting LOP for the X-ray Chassis is 12.8″ approx for the Rem 700 version and 12.9″ approx for the T3 version.
Each pack comes with the screws needed for that specific amount of spacers, i.e. a 4-pack of spacers comes with two screws which are the correct length for using 4 LOP spacers.
The 4-6 Spacer kit is for if you already have 3 spacers and need to go longer on your LOP and has 3 spacers plus the screws to mount 4, 5, or 6 spacers.
Fits: X-ray Chassis, will fit Whiskey-3 with different screws
Restrictions: Requires M4 metric screws to use with Whiskey-3
