Can not find a rt. side charging bolt carrier that suits me, that is not on this Galactic flu back order. I have built several but this is one I plan to pass down. Thinking about filling in the dust cover cut, grinding the sides down to eliminate forward assist cuts, flatten the rt side and maybe do the rails, etc. Afterwards send it to heat treat, do the spec. work, grinding, polishing and send it to get NiB Xed put it together and give it a shot! Cost one leftover carrier, heat treat and NiBx around 225, labor I work cheap at a friends shop. I know that this sounds crazy but one hell of a hobby ain't it. Any thoughts at all?
