Ripcord Industries LDR.P 13" Rail

The "P" stands for "Precision Focussed". The incorporated Arca Rail feature provides a solid interface with Arca-Swiss Quick Release Mounts without the need for any additional accessory or adapter. The LDR.P models have a full-length Arca feature along the 6 o'clock poriton of the rail equipped with Really Right Stuff's RRS-Lock indexing points. This allows end users the ability to utilize tripods and bipods that are directly compatible with Arca. And yes, there are also MLOK slots along the bottom of these rails.

The material for the body of our rail is Aerospace Grade 6061-T6 Aluminum and was chosen for its strength-to-weight ratio, and for its better ductility compared to 7075-T6 used for other rails on the market. This material gives our rail the ability to tolerate high stress, in the event it were applied suddenly, without cracking.     

The LDR.C, LDR.A, & LDR.P all utilize T27, Alloy Steel bolts and a beefy Locking Plate. The Torx drive heads of our bolts reduce the chances of stripping during installation or removal for maintenance. Our mounting bolts sport a fine thread pitch, preferred for use in firearms components as they are less likely to come loose when heat and vibration are present.   

Each length of the LDR Series rail extends as close to the muzzle as it can while leaving just enough space for most commonly used suppressors to be mounted. This allows end users to maintain their normal support hand grip even when mounting various accessories (i.e. lasers, pressure pads, weapon-mounted lights, etc).
