yes, but as you have so clearly stated (not in your OP or thread title, but in a later post) you are looking for AFTERMARKET ADD ON KITS. The bolt is not an after market add on kit.
If you already have a front wired gun, or can switch a rear wired gun to front wiring, you could use the modify aftermarket add on AEG recoil kit.
Hopefully that was clear enough...
