A stock for a small arms weapon which may include a proximal end surface and a distal end surface, the distal end surface including a first opening extending toward the proximal end surface. The stock further may include a multi-lobe chamber connected to the first opening. The multi-lobe chamber may include a primary lobe for housing a receiver extension. The primary lobe may include a track for supporting a bottom surface of a receiver extension. The primary lobe further may include a first side lobe adjacent to the first wall, and a second side lobe adjacent to the second wall. A first insert may be disposed in the first side lobe and a second insert may be disposed in the second side lobe for isolating movement between the stock and a receiver extension disposed in the track.

1. A stock for a small arms weapon comprising: a first member having a longitudinal axis which comprises a proximal end surface,a distal end surface which comprises a first opening extending toward the proximal end surface,a multi-lobe chamber connected to the first opening which comprises a primary lobe for housing a receiver extension which comprises a track for supporting a bottom surface of a receiver extension,a first wall for supporting a first side surface of a receiver extension, anda second wall for supporting a second side surface of a receiver extension,a first side lobe adjacent to the first wall, anda second side lobe adjacent to the second wall;a first insert disposed in the first side lobe for isolating movement between the first side of the stock and a receiver extension disposed in the track which comprises a first side leaf member which comprises a first side base, anda first side resilient cantilever extending from the base such that the first side resilient cantilever deforms under pressure applied by a receiver extension disposed in the track opposite the first side leaf member to isolate movement between the first side of the stock and the receiver extension;a second insert disposed in the second side lobe for isolating movement between the second side of the stock and a receiver extension disposed in the track. 2. The stock of claim 1, wherein the first insert comprises three first side leaf members. 3. The stock of claim 2, wherein the second insert comprises a second side leaf member which comprises a second side base, anda second side resilient cantilever extending from the second side base such that the second side resilient cantilever deforms under pressure applied by a receiver extension disposed in the track opposite the second side leaf member to isolate movement between the second side of the stock and the receiver extension. 4. The stock of claim 1, further comprising a connecting member joining the first insert and the second insert to form a integral shim and damper in the multi-lobe chamber such that the integral shim and damper supports a receiver extension disposed in the track and prevents and isolates movement between the stock and a receiver extension connected to the stock. 5. The stock of claim 4, wherein the first member further comprises an exterior surface and a portion of the connecting member forms a part of the exterior surface. 6. The stock of claim 1, wherein the proximal end surface further comprises a fastener attachment site. 7. The stock of claim 6, further comprising a back plate secured to the proximal end surface. 8. The stock of claim 7, wherein the proximal end surface comprises a second opening connected to the multi-lobe chamber. 9. The stock of claim 8, wherein the back plate covers the second opening. 10. The stock of claim 1, further comprising a a second member connected to the first member which comprises a third end adjacent to the proximal end, anda fourth end spaced from the distal end. 11. The stock of claim 10, wherein the second member further comprises an interior compartment that is configured and dimensioned to house a cylindrical capsule. 12. The stock of claim 11, wherein the cylindrical capsule comprises a tubular member and a cap. 13. The stock of claim 12, wherein the cap further comprises a plug for sealing the tubular member. 14. The stock of claim 13, wherein the cap further comprises a cantilevered block and the tubular member further comprises a projection such that the cap may be rotated with respect to the tubular member to interlock the projection and the cantilevered block. 15. The stock of claim 14, wherein the capsule further comprises a rail and the interior compartment further comprises a channel and a catch in the channel such that the rail of the capsule and the catch cooperate to lock the capsule in the interior compartment. 16. The stock of claim 10, further comprising: a third member connected to the first and second members which comprises, a fifth end connected to the distal end of the first member, anda sixth end connected to the fourth end of the second member. 17. The stock of claim 16, further comprising a web disposed between the first member and the third member. 18. The stock of claim 17, further comprising a spring loaded locking pin disposed in the web such that the locking pin is configured and dimensioned to interlock with a receiver extension disposed in the track to fix the stock to the receiver extension. 19. A method for assembling a small arms weapon stock having a vibration isolator comprising: providing a stock for a small arms weapon which comprises, a first member having a longitudinal axis which comprises a proximal end surface,a distal end surface which comprises a first opening extending toward the proximal end surface, anda multi-lobe chamber connected to the first opening which comprises a primary lobe for housing a receiver extension which comprises a track for supporting a bottom surface of a receiver extension, a first wall for supporting a first side surface of a receiver extension, and a second wall for supporting a second side surface of a receiver extension,a first side lobe adjacent to the first wall, anda second side lobe adjacent to the second wall;passing a vibration isolator into the first side lobe and the second side lobe from the proximal end of the stock for supporting a receiver extension disposed in the track and isolating movement between the stock and a receiver extension disposed in the track; andsecuring a back plate to the proximal end surface to enclose the vibration isolator in the stock.
