So, I'm thinking about building an M16 (or M4) DMR. I'd like to start with a reasonably priced base gun that has decent out of the box performance, and modify it in stages. Ultimately, I plan to heavily modify it, tbb, spring, motor, R hop, anything necessary to perform well and reliably. JG has an M16A4 which is about $170. My brother in law has a JG G36C and he's satisfied with its performance. So far, it's been reliable, and performs decently. I think Echo1 has an SPR and M16, as well as its Red Star CSR Dragunov. Anybody have any advice as to what I should start with?
