WOLF A1 upper, T91 clone. They import these from Taiwan, it was something they got to celebrate making a deal with them for getting M193 ammo to import. I've put somewhere around 250-300 rounds through it. It is a poor man's HK416 or good start to a T91 clone., 400 Trades offers welcome. . Prefer to meet in Harriman, Rockwood, Wartburg, or Kingston.

Optic sold, so just the upper
