Performance Characteristics
The SPR contour excels at cold bore accuracy—that critical first shot that determines your point of impact. Gas port sizing reflects real-world precision shooting demands, accounting for popular bullet weights and suppressor use. This attention to detail means your rifle will cycle reliably whether you're running standard ammunition or subsonic loads through a suppressor.
The 18-inch length strikes an excellent balance for DMR (Designated Marksman Rifle) and SPR builds, providing velocity and sight radius without excessive weight or length. This is a barrel built for shooters who demand precision without compromise.
