Happy new year all !
I'm in the process of trading my upper but the guy wants to keep his bolt. How bad is it for reliability to run non-matching bolt on a used upper ? Thanks |
| Bolts are replaceable items and a rifle that gets a lot of use should have the bolt swapped out at around 10,000 to 12,000 rounds. With that a person should check the head space before firing. Interchanging the bolts, bolt carriers, and weapons may result in incorrect headspace. |
