Spring and Kynshot RB5007 NOT included.
This is to machine the carrier that YOU provide (or if purchasing an upper from me) to remove approximately 1.9 ounces of weight off the carrier.
Also machine the key in half for ‘Extended Stroke’ intended to be used with the JRC buffer tube and Kynshot RB5007. The single bolt is then re-staked.
There is a possibility that the key could slam into the lower so a spacer is required which is provided.
I typically have about a one week turnaround to do these as they are done on demand. I will let you know if I anticipate it will be a longer wait.
