Welcome to Black Mamba engineering, I manufacture airsoft components, build custom parts, modify existing parts, designing new one off parts.
Many Items be manufacted, from simple thread adpaters i.e M16cw to M14ccw, Silencers of any length & diameter & style, flash hiders, fore grips, tripods, outer barrel & barrel spacers(L96), inner barrel mods.
Custom parts are more my area, ris's fitment, machined out slides or grooves, machining slots/holes for torches, made to fit stock adapters. Pretty much the ideas can be endless with airsoft but time & price will always be a factor.
Ill add more adaptive parts as i go along, I can do servicing such as upgrading barrel, wiring, springs, motors, mofset fitment and replacing parts.
