Precision Rifle Recoil plates are designed to fit the Ruger Precision Rifle (RPR) and RPR MAGNUM. The Recoil Plate is made from 6061 aluminum with built in cant adjustment. The LSP-Recoil Plate +0 is the same dimension as the recoil pad #10534 which places the pad on the shoulder at a similar location as the the original. The bolt pattern is specific to the Limbsaver Trap/Skeet -Small - recoil pad #10534 - which needs to be purchased separately. This pad was intentionally selected for its relatively thin side walls thus eliminating the need for grinding. This pad is softer and wider and is good for bench shooting or whatever you currently do. The other taller Recoil Plates (+1 and +2) raise the pad for prone shooting. Included are two bolts that will be inserted into the recoil pad for mounting. Note - The stock recoil pad will not mount to this recoil plate without modification. The recoil plate fits RPR's and RPR Magnum's only. Installation instructions are included with purchase. Tools required are: 9/64 Allen wrench (.140) 5/32 Allen wrench (.156) 1/8 Allen wrench (.125)
