    As far as the M16 goes the M16A3 is exactly the same as the M16A2 except its select fire mode is full auto instead of 3-round burst. No other difference, and neither is a flat top - the M16A4 has that distinction, it has the top rail for removable carry handle/sights/etc.

    That terminology should have been used for commercial AR-15s but instead A3 and A4 both are used for flat tops. And A1 and A2 for receivers with integrated carry handles. Today most people want the flexibility of the flat top.

    Q, respectable knowledge of the cool stuff.

    I want a civilian A1 or a XM177. Two of the coolest ever built.

    Yeah, and some of the manufacturers are starting to take the forward assist off the flat tops.

    yes and no. I go back and forth. When it comes down to it I would rather have one and not need it.

    I dunno, but I almost always use my FA. I let my wife and friends shoot my ARs and its really comes in handy when taking a peek in the chamber to see if there's a live round in there. I dunno about you guyz but I always do a chamber check when someone hands me a rifle (if the bcg out of battery)

    Due to a few of the catastrophic failures I have seen that have been attributed to the forward assist, I would rather not have the temptation in front of me. Yes I know the odds are low it would happen, but the cost of a round verses the damage that could happen made my decision an easy one. Better to eject the round altogether.

    I use it for chamber checks as well. It's kinda like having a comfort blanket.

    I understand and feel the same way. I almost always eject the round if there is a problem.

    I know we have gotten off topic with discussing the F/A. My fault entirely. If someone is upset about it, I apologize.
