Specna Arms / Rock River Arms Licensed CORE Series M4 AEG (Model: M4 Archer / 2-Tone Black and Tan)

"runs pretty good but had a few issues, i had an issue with one of the battery wires coming loose, as well as it not always firing when in semi auto. had to get the wiring resoldered and now i gotta bring it back in to check the trigger

"I may have gotten a lemon but this gun was very sub par. Very poor qc on the externals, horrible airseal. The shimming was alright and the aoe was nice and the price point is good, but I'd say save the money and get something a bit higher end
