Parts Applied

Applied the bolt upgrade and repair kit to Willard's "modern" AR-10.

New extractor and "spring".  The spring is actually a rubber mushroom.

New ejector and spring.

New firing pin.

New cam pin.

New firing pin retainer.

New gas rings.

Checked the gas-key, tight.

Checked the alignment of the gas tube against the key.  Good.

Bolt got cleaned incidentally while I was doing all this part swapping.

Hopefully this cures its ills.

It worked fine for a couple hundred rounds in the .308 comparo we did, ain't been right since.
