Original issue M16's had too many jams and failure to chamber a round. There were other problems as well.

The original M16 was a real Jamomatic. The A1 had a forward assist to help close the breech, a chrome plated barrel and a bigger 30 round magazine. It helped but the gun is still not as reliable as the M1 Garand, M1 Carbine, M14 or AK designs.

The Weapon was not properly field tested.
The Army messed around with the powder used to change the Ballistics.
The Star chamber wasn't chromed plated which with the humidity plagued it with rounds being stuck in the chamber.
It had no forward assist.
Proper cleaning kits weren't issued.
A rumor went around it was self cleaning.
The A1 addressed lots of these issues and was a fine Rifle I actually prefer the A2 and A4 personally.

just updates on the flash suppressor to prevent it from catching on twigs and branchs
crome plated chamber and fulled lined bores, made them easier to clean and several other issues that were noticed in the field were corrected

I used both. In addition to @Daniels comments. The feed from magazine to chamber was glitchy. Double feeds was not uncommon. And the ejector port would stovepipe a shell pretty regularly. And we could never load 30 rounds in the magazine. 29 was the max. If you loaded 30 you'd get a double feed or jam. And the spray and pray on full auto was a waste.

The A1 corrected some deficiencies in the original, most notably adding a forward assist and chrome plated chamber.
Note, the Air Force continued to use the original M16 (with some improvements, but still no forward assist) until the early-mid 2000s, when they switched directly to the A2 (and by switch, I mean replacing the uppers, swapping out the inner workings of the trigger mechanism to fire burst instead of full auto, and stamping A2 and BURST on the lowers). The Air Force also went straight to the M4 for cops and Battlefield Airmen.
