HK USC - Buffer, Barrel Pin, Ejector Lever, Stock Block

Hello. Have brand new HK USC parts (imported from USA):

1. Ejector lever
2. Recoil Buffer
3. Barrel Pin
4. Stock Block - for ACR stock conversion

$225 shipped for the lot.

Trade wise, I’m interested in M1903 Springfields - any model (as long as serial above heat treat threshold for older 03 models); and REM 700 police models.
