I'm not going to debate about what defines a dmr in Airsoft. What I will say is you can make pretty much any gun shoot very accurately by fixing the air seal and assembling a quality barrel group. Accuracy in Airsoft if pretty mich three things: fps consistency, barrel quality, hop up quality.
Certain polymers. The ones used on a Glock and firearms and industrial products are superior to polymer in consumer stuff. Most plastic stuff are molded from ABS.
