M14/M1A bolt question

[Rekraps]

Anyone know what the small hole in the bolt underside, about in the middle is there for?

Good question! I've posted it over on the M14 forums and will post the answer here if we get one.

The consensus is that it's simply a hole for giving the firing pin a little squirt of lubricating oil.

That's what I thought but then it's a free floating pin so no lubricant should be necessary. Maybe it is either a pressure release hole to prevent any gas pressure buildup.... we'll see.

Gas relief hole.

.Gas relief holes were added to later M1 carbine bolts as well.
