I do not recommend it
You can easily buy a .22 cal rifle made by Marlin for the same money

These different upper reciever groups and bolts
are 1/2 the price of a complete rifle.
I would put the money in a match grade .223 Rem cal rifle.
Niether are vary accurrate
You can buy a different style rifle
in these calibers for less money that the upper reciever
group. They offer no real advantage.
