Product Summary
The Kaw Valley Precision Extra Power Recoil Spring is designed specifically for AR-15 pistol caliber carbines chambered in 9mm, .40 S&W, .45 ACP, and 10mm. Constructed from durable 17-4 stainless steel, this medium-weight spring provides increased pre-load to help keep blowback systems closed longer. This increased dwell time protects internal lower components from damage, which is especially critical when using a suppressor. It is an essential upgrade for shooters looking to reduce felt recoil and quiet their action in carbine-length setups.
