Final corrections as best I know...
Stag barrels are parkerized under the FSB.
While stag barrels use taper pins, they are installed backwards and tight as hell. (this is neither a + or a - in my book)

There are limited runs of M4 feedramped Bushmaster uppers, particularly for the Texas DPS.
The dealer that sold these made a bunch of extras and I see them through my shop occaisionally.
I have NEVER seen a Rock River barrel that used taper pins.
This does not mean that the particular model in the chart does not use them, I've just never seen one through my shop.
It would be very odd indeed to use taper pins only on one particular model and then use straight pins on every other model.
Man, I thought I had already corrected all three of those!
Guess I'll have to fix 'em tomorrow.
Didn't someone mention that a LMT could be had for around $1000 in a different thread? I could be mistaken though.
