Strike Industries products are designed by shooting experts for the shooting sportsman.

The SI Stock Stop is the easiest, most affordable way to convert your collapsible stock into a fixed stock. To ensure the stock cannot be adjusted to another position, all but one locking stop on the receiver extension is blocked by the tough thermoplastic polyurethane device.

Compatible with aftermarket 6-position buffer tubes or Strike’s 7-position Advanced Receiver Extension, the Stock Stop requires no modification to the buffer tube. Simply cut the device to fit. Keep the look of a collapsible stock in a fixed configuration.

Notice from the manufacturer:
“This device is made to conform to the DOJ criteria but has not been approved.  If the Stock Block is used in conjunction with other features on the CA DOJ banned features list, the host system no longer constitutes a “featureless” build.  Please consult your local laws and regulations to ensure compliance.”

Great Product

This little polymer catch/stop is awesome. Super easy to install. Requires no modification of the stock or buffer tube. Allows for standard removal procedure to swap out different stocks. Best fixed stock mod on the market.

Cut into use as stock limiter


Using this as a stock limiter to stop stock extension where I want it after collapsing it for storage or transport.
