Grand Power Stribog SP10A3 & SP45A3 Locking Block – 35° Degree (10mm / .45 ACP)

Tailored for the larger caliber Stribog SP10A3 and SP45A3 platforms, this 35-degree locking block works with both 10mm and .45 ACP models. It reduces bolt velocity for a softer, more controlled shooting experience-especially beneficial when running suppressed or with highter-pressure loads. Perfect for tuning your Stribog to strike the right balance between smooth cycling and reliable function.

Features:

• Provides smoother and more secure engagement of the charging handle, especially under the higher recoil forces of big bore calibers.
• Maintains structural integrity during extended firing sessions, including suppressor use—won’t warp or degrade under heat.
• Prevents accidental handle movement, improving safety and reliability during operation.
• No gunsmithing required—easy to install and compatible with all factory and HB Industries charging handles.
• Ideal for tactical or suppressed setups where stealth is important.
