The upgrade will replace the most complex part of the bolt. That being the ring that is the locking lugs, cocking ramp(s) and bolt handle.
If you have a V -3 bolt that is has not been modified in any way, it may just plug and play. But if the thickness of the new piece and your existing piece isn't exactly the same then the new piece will have to be modified to maintain headspace.
If they are the same, anyone that can disassemble a Turbo bolt will be able to install the parts.
If you send just your bolt to Anthony, he will do the mod for you. Price is $600.00. plus shipping.
