Is this an a1 a2 a3 or a4 style upper?

Expert Answer
A
Answered by Ethan C., Gear Expert, from IL, United States, on June 21, 2018

This does not technically fall into any of the A-series designations, rather it is a unique upper receiver design from Guntec. It will still fit all standard AR-15 parts.
