NSCW Crane Division extractor upgraded with Viton® O-ring, 5 coil spring, and plunger
HTP/MPI Tested:
HTP/MPI test, our material is checked prior to machining by our supplier of 9310
Q:
Can this bolt be used in a piston ar (as is)?
Asked by:
Neilbd
- 7/3/2020
A:
We use these bolts in our piston and direct impingement builds. As long as your piston rifle uses a mil-spec bolt assembly you should be good to go.
Answer provided by:
Administrator (7/3/2020)
A:
Yes, we use them in our piston rifles. The bolts are mil-spec dimensionally and should be able to be used in any AR-15 upper unless a piston upper utilizes a proprietary bolt assembly.
