I built a Mini30 into a M1a with the help of Accuracy Systems] Attachment 228988Attachment 228992and remilitarized a 1930 vintage 1903 Springfield sporter with a 21 inch bbl by making the stock fit the short barrel. The Mini was a real challenge to get the mini action to fit in a M14 stock. Lots of jbweld and a couple of walnut blocks. My first rattle can paint job too. The ‘03 was just a stock refinishing and shortening of the stock and handguard which is actually 2 handguards. The high hump end is shortened and cut while the slender part is from another guard and was shortened at the rear. The lower band hides the seam. My current build is going to be a Mini .300 blkout/Garand T20.
