@edd217 It allows you to seal the bolt forward if it is fouled and doesn't close properly, which would lead to a failure to fire.

Very informative, and very well executed, but one solid piece of advice from gunsmith to gunsmith when installing a roll pin with a guide punch, just get the pin started, try not to continue hammering it in with that punch, I've seen a few of my counter parts chip off the ends, and bust those punches pretty bad, i suppose it is a double edge sword tho, either that or you mushroom head the pin, and using a plastic hammer only tears up the end of the hammer.

@edd217 if you put in a new mag and release the bolt, but it doesnt go all the way forward because the round is a little stiff, you push on the forward assist to force it into place.

I can't wait to see them all. I'm familiar with the build process, but really want to see it done your way, Gavin.
