Patent ID: 7992337

Claim:
A method of mounting recoil dampening apparatus on a rifle including a stock comprising the steps of (a) providing an adaptor ( 24 ) to be mounted on the rifle after the stock is removed, said adaptor having a cylinder bore therein (b) providing a recoil dampening unit including (i) a shoulder butt ( 21 ) (ii) a slidably displaceable member with a first end to be slidably and rotatably mounted on said adaptor such that said first end is mounted within said cylindrical bore of said adaptor, and a second end ( 67 ), (iii) apparatus to adjust the length of said unit, and (iv) apparatus to permit said slidably dispaceable member and the rifle to recoil and move toward and relative to said butt when the rifle is discharged and including a base ( 20 ), a stop ( 39 ) with contact surface ( 38 ), a housing ( 19 ) mounted in said base ( 20 ) and including a hollow bore extending therethrough, said second end ( 67 ) slidably extending into said hollow bore, at least one resilient member ( 32 ) in said hollow bore inside said housing and including a primary end contacting said contact surface ( 38 ), and a secondary end ( 68 ) directly contacting said second end ( 67 ) of said slidably displaceable member such that said slidably displaceable member compresses said resilient member ( 32 ) against said contact surface ( 38 )during the recoil of the rifle, said first end and said adaptor shaped and dimensioned to (v) permit the cant of said unit to be rotationally slidably adjusted to at least a first selected cant, and a second selected cant less than ninety degrees from said first selected cant, (vi) mount said unit on the rifle at at least a first selected slope, and a second selected slope different from said first slope with respect to the rifle to facilitate positioning of the shoulder butt against a user's shoulder; (c) removing the stock from the rifle; (d) mounting said adaptor on the rifle; (e) inserting said first end of said slidably displaceable member in said adaptor to mount said unit at one of said first and second selected slopes; (f) rotationally adjusting the cant of said unit to one of said first and second selected cants; (g) adjusting the length of said unit; and, (h) fixedly securing said first end on said adaptor.
