Im pretty new to the AR15 carbine, and Im wondering about the strength of bolts. The reason I ask is because, for example, when looking at TangoDown vertical grips, they show how a backup bolt can fit in there. Same with some stocks Ive seen. So are AR15 bolts so fragile it would be wise to carry a whole new bolt with you? While I have my rifle for general fun, home defense and SHTF, I am asking in general for all users - all the way from the plinker to the Marine Corps/special forces types. Is this something the Marines really need? Is this something I really need? (The carbine Im using a bushmaster M4 if it matters) Does anyone have any idea what the MTBF (mean time between failure) is for these bolts? |

So long as you get a bolt from a quality source you -shouldn't- ever have a problem with it. But it's one of those parts that takes teh rifle completely out of the fight if it fails. And it doesn't have to be the bolt actually breaking, it could be something small like a small brass shaving from a case getting stuck in the ejector. Swapping out the bolt is a lot faster than trying to troubleshoot the problem in the field. In speaking of breakages and spare parts, you should keep the other parts too. Cam pins and cotter pins are small enough to drop and lose when cleaning the rifle. Firing pins are very durable but they can still crack, chip, or erode. |
