Great Quality Bolt. by Douglas, Verified Owner, June 29, 2024
Cryptic is known for their great quality. I paired this with a Geissele RE bolt carrier. Fits perfectly, checked it thoroughly with my micrometer & calipers. Also their firing pin protrusion was within spec. Will definitely be getting more.
