The SOLGW Precision SPR V2 barrel solves the suppressor zero shift problem with an 18″ design optimized to maintain zero when adding or removing cans. This barrel works well for precision shooters needing 6mm ARC ballistics with suppressor capability, hunters wanting extra velocity from the 18″ length, and anyone building an SPR where zero consistency matters. The polygonal rifling with 3-groove bore improves accuracy while the rifle-length gas system keeps cycling smooth and soft – bringing SPR-level precision to 6mm ARC builds with proven SOLGW quality.
Note: Requires 6mm ARC bolt.
