The stocks of early models were susceptible to cracking, sometimes attributed to the shape of the receiver; later models, such as the dovetail scope variant, appeared to solve this problem. The pump grip of all models is susceptible to cracking, the wood between the magazine and barrel being especially thin, this rarely detected unless the rifle is disassembled.
Although the rifle was never commercially imported into the United States, many have made their way there by way of returning service members, small lots, and other various means.
