  • Publication number: 20120222342
    Abstract: A pistol grip recoil assembly for a firearm includes a rigid grip body formed with rest structure thereon and connected to a firearm. A substantially elastomeric, resilient and deformable grip insert is received in the grip body and forms a shock absorbing, cushioning backstrap engageable with the palm of a user's hand for minimizing recoil caused by discharge of the firearm. The grip body and grip insert are slidably engaged together by means of a dovetail arrangement and secured together thereafter by a means of a fastening structure.

  • Patent number: 8215046
    Abstract: A mounting arrangement for use with a shotgun or rifle to selectively position accessories along the barrel of the rifle. The mounting arrangement includes a forend and a series of mounting rails that receive the desired accessories. The forend includes a series of locator rails equally positioned around the outer circumference and spaced from each other at approximately 45°. The spacing of the locator rails allows a user to selectively attach an accessory in a larger number of desired locations around the outer circumference of the forend. Each of the mounting rails and locator rails engage each other in a dovetail configuration to prevent the radial separation of the mounting rail from the locator rail.
