I am trying to put together a DSG out of a lancer tactical and was wondering if anyone had any ideas/suggestions to improve it. Parts: Rocket/SHS DSG GATE Aster Aztech Apache tappet-less cylinder head (airsoft version) 30/35k motor (suggestions?) 300~350 fps spring with spring guide. Aiming for 30-40 rps @ 300-350ish fps. Trying to build it using as many stock parts as possible (minus those mentioned above) without have poor quality. If you have any suggestions for other parts, please let me know! Thanks!
