V3 HPA Adapter "base" for use with WE-TECH M4 (or M4 compatible) and the Builder Tool.

This is the base only: use the Black Variable Adapter Builder Tool. This does include the HPA fittings.

Note: This is made-to-order. Estimated fulfillment is 2 weeks minimum, but could ship earlier.

Note 2: Version 3 uses a different mounting system compared to older versions.
