Is it absolutely nesesary to switch out your bolt with a new one after a barrel change? If so, bolt only or do i need a completely new BCG to go with the new barrel.
I will be changing out the 16" middy barrel my BCM came with stock, for a 18.5" Ultramatch SPR unit. Just asking. Thanks J |

Quoted: By the way, the BCG along with the bolt have less than 500 rounds through. Just so you know. J Barely broken in. Look at the backs of the lugs, if all are shiny, the bolt is broken in. That is the reason for the caution, every bolt/barrel extension will eventually "wear in" with SLIGHT increase in headspace (on the order of 0.0005"), then headspace will remain constant. Swapping bolts will cause this wear in to progress. One swap? Not usually an issue. |

Quoted:
How you install the barrel will be a larger factor than a slightly used bolt (500 rounds might as well be new). If you want get a new bolt and allow both to wear as one. That's what i was figuring. Would you explain how could i bust up the accuracy of my rifle on the barrel install process? This is my first install i don't want to be fiddling with it after it's bolted on. Thanks J |
