GUARDER Rubber Butt Pad for CAR15 / XM177 (M4)
GUARDER STOCK-01 rubber butt pad is a simple accessory for CAR-15 / XM177-type retractable stocks (early M4 prototypes derived from the M16), which makes shouldering the gun more comfortable and helps keep the stock in place during shooting and rapid handling. The flexible rubber provides a grippier contact surface than the stock's plastic alone and also adds approximately 20 mm to its rear. The pad measures 52 × 112 × 20 mm and weighs 60 g, making it a small and straightforward upgrade for players who find the original stock end uncomfortable. When choosing, we recommend comparing the dimensions of the rear section of your specific stock, as the CAR15 designation is used for a range of differently shaped retractable stocks and compatibility with the gun's buffer tube alone does not guarantee a matching butt pad shape.
Key Features
Flexible Rubber Construction
The rubber material creates a softer contact surface between the stock and shoulder, making the gun more comfortable to shoulder.
Reduced Shoulder Slippage
The grippy rubber surface helps reduce stock movement against clothing or tactical gear when aiming and handling the gun.
For CAR15 / XM177 (M4) Retractable Stocks
The pad is designed to fit a corresponding CAR15 / XM177 / XM4-type retractable stock. It is worth comparing its dimensions with your specific stock before ordering.
20 mm Thickness
The pad has a thickness of 20 mm, so in addition to providing a softer end, it slightly extends the rear of the stock.
Simple Stock Upgrade
The slip-on design allows you to easily modify the end of a compatible stock without altering the gun's internal parts.

Frequently Asked Questions (FAQ)
What Is the Rubber Butt Pad For?
The pad creates a softer and grippier end for the stock. It improves contact with the shoulder and helps reduce slipping when aiming or moving with the gun.
Does It Fit Every M4 Retractable Stock?
No. M4 retractable stocks come in many different shapes. The pad is designed for a corresponding CAR15 / XM177-type stock, so we recommend comparing the shape and dimensions of its rear section before purchase.
How Much Does the Pad Extend the Stock?
The pad itself is 20 mm thick. Once fitted, it therefore adds approximately this amount to the rear of the stock, although the actual change in length of pull depends on how it seats.
Is the Pad Hard or Flexible?
It is made from flexible rubber, which conforms better to the end of a compatible stock while also providing a grippier surface against the shoulder.
