Smith&Wesson has the black incert in their extractor spring also they have the #60 size O-ring. If the bolt is stamped with MP it's Mfg. by LMT Lewis Machine&Tool.

Damn, after looking at the chart, now
I find out that none of my Bushies have
a lifetime warranty!

Looks as though Colt has all the bases
covered and is the front runner, if I
interpret the 'X' properly.

Another item of interest according to the
chart: chrome lined vs. chrome/moly lined.
I do not see the latter listed at all but most
of the manufacturers make the claim.

Thanks for posting this.

I knew there was a reason why people liked those Colts so much.

Sure thing.

I wouldn't hesitate at all to rock out with a STAG though.

Charts like this are stupid.

It's funny how some people see charts like this made up by one guy on the internet and all of a sudden it's an authority on AR15's...

Some of the stuff listed on that chart are straight up wrong and/or misleading too, although most of it is seemingly technically correct...

Some of the things listed mean something (like MPI'ed bolts, chrome lined barrels, etc...)... but...

A lot of the things listed on that chart mean absolutely nothing.

Seriously, does it matter if my AR is parked under the FSB? no.

Do the FSB pins need to be tapered? no.

Does it matter if I have M4 feedramps on my semi auto? no.

Do I need dual heat shields? no.

Is a 1/7 twist the optimal twist? Not to most.

Some will argue that high pressure testing will actually cause undo stress on the parts being tested...

Another thing to understand is that in some cases, not being milsepc can actually be better. One instance for example is that of LMT barrels, which are overbored. It's not milspec, but it makes for a much more accurate chrome lined barrel (better than Colt). Why isn't that on the chart?

Anyways, I could go on and on...

Just a simple list for conversation. Its not intended to be a bible. Sure, an AR doest have to be mil-spec, or have M4 feed ramps to be reliable. There is a difference between quality and crap though. Yes a colt is nice, but I wouldn't hesitate at all to defend myself with a STAG.

You know the phrase "properly staked gas key" gets you all hot and bothered.

So, where does my 9mm AR fit in? Oh yeah... I don't care.

Sorry. I guess ARs mean different things to different people. I guess for some, part of the fun is being as mil-spec as possible. Others, like myself, just like to shoot and have fun. Weeeee!
