  Standard Power - Rifle Length - Buffer Spring + XP 5-Coil Bolt Extractor Spring The Green spring is for use in A1 / A2 fixed stock rifle length buffer tubes with rifle length buffers. It is also extremely popular in intermediate depth (7.75 “ deep) VLTOR A5 buffer tubes with 4” A5 buffers. The spring design loads of the Green spring are those of a BRAND NEW mil-spec buffer spring. While the Green spring is primarily for use with lesser calibers such as .223, 5.56. 6.8 SPC, 6.5 Grendel, 7.62 X 39, etc. in A2 rifle length tubes, it may sometimes be appropriate for use in long BBL (20”+) rifle length gas BBL’s in heavier calibers such as .308 and 6.5 CM, .260 Rem, etc.. (May not be effective for unsuppressed 7.62 X 51) In the latter scenario, an H2 or H3 carbine buffer has been used successfully in rifle length tubes with the Green spring. Over gassed heavier caliber guns with rifle length tubes may be addressed with our Red or Orange carbine springs and standard length 3.25” carbine buffers along with a spacer to yield the appropriate tube depth for the longer BCG’s. Color Coded GREEN.   AR-15 Standard Power Buffer Spring GREEN - Rifle Length Features: Standard Power Rifle Length Buffer Spring Compatible to AR-15 with rifle lenght gas system and rifle length buffers Possibly compatible to AR-10 (20”+ barrel) normal gassed guns with rifle lenght gas system in conjunction with H2 or H3 carbine buffer (May not be effective for unsuppressed 7.62 X 51) NOTE: Overgassed AR-10 guns with rifle length tubes may be addressed with our Red or Orange carbine springs and standard length 3.25” carbine buffers along with a spacer!

   JPSilent Captured Spring Buffer Retainer Pin and Spring While you can use a standard buffer retainer pin and spring with your Silent Captured Spring, installation and removal is difficult to say the least. Until now, that's left the only option of storing the SCS loose. Fortunately, we have a solution. This new buffer retainer pin design allows for easy installation and removal of the Silent Captured Spring while ensuring unerring retention. Your SCS will never drop unexpectedly out of your lower again. Plus, this design works equally well with a standard AR buffer and spring. It's a little thing, but what a difference it makes. Compatibility: Like a standard buffer retainer pin, this design is not compatible with Variable Mass Operating System (VMOS™) carriers. This buffer retainer pin is designed to work only with conventional buffer tubes and not those with a slotted lip feature designed to extend around the buffer retainer pin. The slotted feature may prevent this buffer retainer pin from fully presenting and will not retain the SCS. When running a Silent Captured Spring in this type of buffer tube, we recommend against use of buffer retainer pin. This buffer retainer is designed for use with the JP Silent Captured Spring and will not retain a standard buffer assembly as well as a Mil-spec buffer retainer.  MADE IN THE USA
