DESCRIPTION

The Area 419 ARCALOCK 14.25" Universal Weight-Tunable Rail with 5 Weights brings next-level customisation and balance control to precision rifles. Expanding on the proven ARCALOCK system, this tunable rail has been engineered to meet the rising demand for adjustable rifle weight setups, particularly within competitive shooting disciplines. Designed to fit the vast majority of Manners PRS-series stocks, the rail provides both mechanical ARCALOCK locking and the ability to fine-tune rifle balance by adding or removing the included brass weights. At 0.400" thick and constructed from hard-anodised aluminium, the rail offers excellent rigidity, durability, and expanded space for accessory mounting. Whether you're adjusting recoil behaviour, modifying your rifle’s centre of gravity, or aiming for a more stable positional shooting platform, this universal ARCALOCK rail delivers flexible, reliable performance tailored to your shooting style.
