Currently, I've fitted a used PRIME GBB upper into an INOKATSU GBB lower, the job has done and now dismental the upper and lower for acid de-blueing and found out the INOKATSU GBB lower are exactly made inaccordanced with Mil-spec standard, an existing layer of hard oxide anodised to receive final layers of anodised blueing (after acid cleaning), because of that hard layer I've to spend extra for sand-blasting for both upper and lower receivers to achieve uniform surface texture to match the colour for re-anodizing, and the re-blue of the outer barrel and fittings as well. Only these small steps took additional 2K, but the final outcome should be good. This gun definitely look original INO M4 and definitely for indoor only. The second INO GBB M4 will fit another new PRIME upper and this time will play those so-called private security or personal defence weapons whatsoever style......
My next project is to build the most (actually reasonable) robust WE GBB for outdoor game. Seem it has the CO2 mags, the proposed PRIME body will be available in due course, and will custom machining a one-piece 6061 steel barrel (maybe aluminium barrel instead), will try to black dye the copper sleeve and as many imported gadgets as possible. Got the MK18 DD rails, ergo grip, magpul trigger guard, Troy BUS ....... hope will have time to finish it.
