223/5.56 field case 10rds

10rd capacity screw top ammo case. Case Index's off the shoulder keeping the bullet out of contact with the case.

Take some spares on a hunt or to the range.

Print the cap separately. The print profile has a slower speed and finer layer height to insure better threads. 

Extra profile that includes a TPU insert to glue to the inside of the cap to silence things a bit.
