WTT/TS M4 for KWA M16

http://i.imgur.com/CXysc.jpg this is my M4, originally A&K (DPMS re-brand) but is far from stock anymore so cant really call it that anymore (body is original)...ive priced all the parts at around $550 but would part with it for $400 or trade, would NOT include PEQ15: looking for a KWA or equivalent M16, would love one with front rails but not a necessity obviously

hit me with any questions
