ACR 5.56 Barrels - 18.5" and 16"

Hello. Have two ACR barrels for sale - stored in oil since purchase:

1. 18.5" Dlask - ACR barrel. Told was less than 100 rounds. No hardware. $500
2. 16" B MP marked - ACR barrel. Gas block (no regulator), locking ring and spacer attached. Unknown round count. $500

Shipping is extra if purchased individually. If you buy both, I will cover shipping. 

Trade wise, interested in M1903 Springfields (any variant; as long serial above heat treat threshold for older 03 models); or Rem 700 police models.

PAL will be verified for all purchases.  

Thanks for looking.
