I just got in my second m53 kit and noticed very quickly that where it was torch cut is at least a full inch further forward than my last one. The BRP stampings I used last time don't reach this far forward. I could fabricate an extension piece but I would much prefer not to. I could also buy one of the crushed midsections and bend the part I need back into shape. I do remember some time over the past year or two seeing someone selling a receiver extension that makes up the difference however I cannot remember who sold them. Dose anyone here know where I might find one?
My kit is from Sargesmilitarysurplus, the fact that it came with a barrel was very appealing as well as some of the features are slightly different from my last one. Also I couldn't find many places that had any.
