Advice on drilling into a bolt carrier

[1168]

I asked what exactly he was drilling and he never responded, so not exactly knocking anything. There is absolutely zero reason to drill into a carrier. Zero. The only possible reason would be if a fastener broke off and had to be drilled out. There’s no need to encourage and educate someone on how to compromise the integrity of a critical firearm component by doing doing something ignorant.

You said “zero”, twice, but then gave a reason.
There are two other possibilities. Trying to make a sidecharger, and experimenting with reduced mass using existing parts. I think both are bad ideas, but I have attempted one of them. Unsuccessfully.

This isn’t a particularly dangerous endeavor, just not a beneficial one.

One well known reason to drill holes in a carrier is to pin a weight in place. Like adding weight to some of the odd calibers to slow down bolt speed. It's done more often than you might think.
