Heavy 45ACP carbine buffer and XP Wolff spring.
8.5 Ounce weight and longer body dampens recoil significantly for a more comfortable shooting experience and protects from breaking your bolt catch.
Designed specifically for SBR's and suppressed 45ACP AR-platform rifles the 45 Heavy buffer is made with extra Tungsten to delay the rearward movement of the bolt and dampen recoil resulting in a smoother action. Can also be used with 9mm AR's if you need an extra-heavy buffer similar to the 9mm Q-buffer.
303 Stainless steel body, works well with suppressed rifles also.
