If you want mil spec buy the colt.

Anything else will probably work just fine.

Never had one break or move. Should I be worried?

Not true.

The McMaster-Carr tubular slotted spring pins linked twice in this thread are made to MS16562, which is the governing military specification.

Never had one break or move. Should I be worried?

No.

Damage Industries has all US made parts.

Wait! Has anyone figured out if milspec grip screws are flathead slotted or Allen? I have both at home.

Flathead

This begs a thread suggestion... how many parts that are AR milspec can be ordered just from McMaster-Carr and trim down the kit costs? (Then again, that might be more of a "Can it be done vs SHOULD it" because of the proprietary parts like detents etc...)

Roll pins and gas block screws. Maybe they grip screw. That would be about it.
