KRG's Length-of-Pull Spacers for the X-Ray and Bravo Chassis. They can be used with the Whiskey-3 but will require the shooter to source different screws.
Each spacer is 3/8". Starting LOP for the X-Ray Chassis is 12.8" for the Remington 700 version and 12.9" for the T3 version.
This 4-6 Spacer Pack kit is to be used when you already have the 1-3 Spacer Pack that is included with the X-Ray Chassis. Each pack comes with the screws needed for that specific amount of spacers (4, 5, or 6).
