Universal Weight-Tunable ARCALOCK Rail


Out of stock


ARCALOCK has been a huge success since its release in July of 2018. As the rails have become more popular, we have also seen the rise in popularity of rifle weight kits. With the introduction of the Manners TCS stock in late 2019, we designed and built an ARCALOCK weight system, and are ready to make it available to the general public. This is the 14.25″ Universal ARCALOCK Rail!

WHAT WILL IT FIT – Lots of things. We anticipate this will fit about 98% of Manners PRS1, PRS1, T2A, T2A GAP, T4A, T4A TEAM and T5A stocks. If you’re not sure if it will fit your rifle, you can use the hole spacing print AVAILABLE HERE and some basic common sense to figure it out. We made this as universal as possible, while still retaining weight tuning capability. These kits will come with t-nut hardware to add attachment points if your factory-installed attachment points do not line up with our mounting slots.

WEIGHT – The bare rail weighs just over 6oz. With all 5 included weights in the rail, the weight ends up at about 23.6oz. Each weight weighs 3.5oz.

THICKNESS – These rails are .400″ thick. For reference, our standard 14″, 12″ and 10″ Universal ARCALOCK rails are .270″ thick.

FINISH – Rails will be black hardcoat anodized, and the weights will remain raw brass.
