Armaspec Stealth Spring - Big Bore

Smooth Cycling & Recoil Reduction with the Armaspec Stealth Spring - Big Bore

The Armaspec Stealth Spring - Big Bore (ARMASPECARM253-BB) is a single-stage, drop-in multi-stage capture spring system engineered as a direct replacement for standard AR-15 buffer assemblies. Specially tuned for big bore calibers, this system smooths out action cycling while dramatically reducing felt recoil and operational noise.

Key Features & Specifications:

• Drop-In Replacement: Installs effortlessly into your standard buffer tube without special tools—simply swap out your factory buffer and spring.
• Recoil & Sound Reduction: Significantly reduces felt recoil while preventing the buffer spring from rubbing against the inner wall of the buffer tube, eliminating annoying "twang" noises.
• Constant Tension Design: The buffer mass is engineered to remain under constant spring tension against the bolt carrier group (BCG), promoting smoother cycling and lockup.
• Quiet Metal-Free Contact: Features a durable rubber O-ring on the head of the buffer mass that prevents metal-on-metal contact upon impact.
• Big Bore Optimized: Specifically weighted to manage the increased bolt velocity and cycling demands of large-caliber AR builds.

Upgrade your firearm setup with quiet, smooth, and consistent performance using the Armaspec Stealth Spring Big Bore assembly.
