They're genuine US military receivers, hand fitted and headspaced with military bolts by a gunsmith for perfect fit, refinished to exact military specs, and paired with a hand-shaped stock. They're the pinnacle of a 1903A4.
They're so damn correct that we asked them to build us some of the USMC 1903s with the long Unertl scopes and they said no, because they didn't have any receivers on hand with the correct serial number range to have been actual USMC sniper 1903s. The hand-shaped stocks to exact original milspec is so precise that they have the correct inspector stamp for the serial number of the receiver, matching the original production inspection stamps from seventy+ years ago.
That is how much attention to detail they have.
The last ones we had in were $1599
