The rifle is worth roughly half of what it would if there was no scope. Like ART says, I'd guess $375.00 to $450.00 as a shooter. Zero collector value. I really don't get the idea of scoping any carbine. Never mind an M1 Carbine.
Gunparts wants $17.75 for a 5 round mag(made out of 15 rounders and were never issued by any military). New original 15 rounders are $39.95. $19.95 with surface rust. $49.95 for a BNIB, still in the wrap Irwin Petersen mag. $29.95 for 'used' minor surface rust, Parkerized 15's.
$24.95 for a newly made 30 rounder. $39.95 for an AYP marked 30 with "minor wear". $34.95 for a "used, fair condition" 30. Look in poor condition to me.
"...original USGI bayonet..." Condition matters a bunch. Gunparts lists "damaged Issue bayonets at $59.99 with no scabbard. Very good to excellent Dutch M4's run $95.75 with no scabbard. $100 with a scabbard.
Ammo will depend on who made it.
Spelling and grammar count!
