JL Billet's ARCA Mlok Adapter - Available in 3", 8", 9" & 10"
Made from Aircraft grade aluminum and hard anodized, the JL Billet Arca style rail attachment is more versatile and secure than a traditional Picatinny rail or Harris bipod mount. Arca rails are compatible with a wider range of accessories, including Arca-Swiss style tripods, bipods, and mounts. They are also more secure, thanks to the Arca-Swiss quick-release system. This system allows you to quickly and easily attach and detach accessories without having to re-zero your scope.
Advantages of using an Arca style rail attachment on your builds:
More versatile: Arca rails can be used with a wider range of accessories than Picatinny rails. This is because Arca rails have a dovetail profile, which is more compatible with Arca-Swiss style accessories.
More secure: Arca rails use the Arca-Swiss quick-release system, which is more secure than traditional Picatinny rail mounts. This system uses a lever to lock the accessory in place, which prevents it from coming loose during recoil.
Quicker to attach and detach: The Arca-Swiss quick-release system makes it quick and easy to attach and detach accessories. This is a major advantage for long-range shooters who need to quickly change their setup between shots.
