MasterPiece Arms is out with an add-on folding stock for their 9mm, .45ACP and 5.7mm carbines. While the press release doesn’t specify, it folds to the left and appears to allow the rifle to fire while the stock is folded. While we’d love to slap one on one of their guns to see for ourselves, TTAG’s on MasterPiece’s no-fly list. If you own an MPA gun and decide to give the folder a go, ping us at firstname.lastname@example.org and give us the full 411 . . .
