Cross Armory CRSL Stock Lock Converter for AR-15/M4

The Cross Armory CRSL Stock Lock Converter is an essential accessory for AR-15 and M4 owners looking to meet fixed stock requirements in restrictive states like California and New York. Crafted from durable 7075-T6 aluminum with a sleek black finish, this stock lock allows you to convert your adjustable stock into a secure fixed version without permanently modifying your firearm. Its unique design permits attachment at any point on the buffer tube, offering flexibility beyond standard pin holes. Ideal for those transitioning to a featureless setup, the CRSL Stock Lock comes complete with two Allen wrenches for easy installation.
