There was no perfect transition from the A1 to the A2. The new rifles were fielded to units in waves over months, not a 100% exchange on one single day. Reserve and National Guard units had the older rifles longer. Armorers had a mixture of replacement parts. Yes, there were A1 buttstocks with and without trap doors issued and in service at the same time as well as different grips. All the triangle hanguards I ever saw were made of fiberglass. As the finish on the fiberglass was abraded and worn off the fiberglass sheets created a mottled appearance.
