UPDATE ON ETERNAL PARTS

-anyone planning on replacing your current comm. spec. butt-stock from the TK-KJW M4 please read the following before proceeding!

DO NOT REMOVE THE BRASS BUFFER TUBE! if you are going to remove or change the factory butt-stock AND are replacing it with a Magpul PTS UBR/PRS
the Magpul UBR & PRS come with a buffer tube replacement, DO NOT USE THIS FOR YOUR KJW M4! THE THREADS ARE TOO WIDE AND THE TUBE ITSELF IS 3MICRONS TOO BIG
to properly change the factory stock to a Magpul PTS UBR or PRS; simply remove the reciever extension (prt#50) and reciver end plate (prt#51)...KEEP EVERYTHING ELSE THE WAY IT IS! after removing said parts, assemble the UBR/PRS minus the replacement buffer, slide the assembly over the factory buffer and tighten the tension screws...then voila! you have successfully added a Magpul PTS product to your KJW M4...

the reason for this tutorial is to keep you (the kjw m4 owner) from snapping your clear lower to shrapnel, whence trying to remove the factory buffer.
