?? – I wouldn’t have thought the A1 would have the shell deflector lug.

Also, I believe there are some differences (that escape me at the moment) between the AR-15 and M16 versions of at least the A-3 designation.

Maybe I'm just making things too complicated!

Yes you are...

SGB got it correct

So, then an A4 upper is a flattop M4 Upper....right??

The differance between the A3 and A4, is the A3 has a 3 round burst and the A4 is full-auto.

Dont forget that some of the earliest "A1" mods had NO fwd assist (which is useless I find).
The next time I need the fwd assist on my SP-1 CAR will be the first time. I hear of them being needed but I never have and though I may not shoot as much as a lot of guys I have put close to 5k thru this one I think. Not a burp.

The M-16 has no forward assist, the M-16A1 has a forward assist. The former is the airforce rifle, they did not see a need for the forward assist, and the army would not take it with out one.

AND..., i'll add this:

if you never used your forward assist..., you ain't shootin an AR-15 !!!!!

i guess it's just a habbit, but i ALWAYS push on mine after releasing the open action on a live round

Yup..........just like uncle taught me

And i'll add, Don't ever use the FA. unless you want a disabled weapon. Get rid of any round that fails to chamber never cram it in. If you want to quietly chamber a Rd. your thumb makes a better cartridge assist. I speak from experience Dont Push a BAD Rd. in the Chamber

I agree 100% with Armson-oeg the fwd. asst. is all but useless for his stated reasons.

huh,, I wonder what im shooting then? Seems the rifle I shoot has never needed any kind of fwd asst. The only jam its ever had was when I didnt seat a mag all the way and a fwd assist would have been of no use.
Just aout curiosity if fwd assist is so necessary why is there no other rifle in world that has it? I dont think there is but I could be wrong.
I guess I opened the can of worms on the old fwd assist thing.
