The gun appears to be an Arisaka rifle, likely a Type 99 model. The etching on the stock is not standard. Likely a customization. It also appears to have a scope attached, and a standard shoulder strap.
The bolt definitely looks more like an Arisaka than an M1903. And the brass clip & silver-colored bullets say "7.7x58mm Type 99" to me. Either that or Turkish 8mm Mauser ammo, but that's definitely not a Mauser bolt either.
The metal extending that far back from the trigger guard is definitely an Arisaka feature. The two piece stock required it. I'm saying sporterized Arisaka.
