Spike's Tactical ST-T1 Buffer 3.0 oz
The Spike's Tactical ST-T1 Buffer is high quality AR15 carbine buffer filled with tungsten powder instead of solid weights. Buffer body is aluminum with an attractive and durable black finish. This buffer is standard weight of 3.0 oz. as opposed to a heavier H series buffer weight. Due to it's light weight and quiet operation, it makes a great option for .300 BLK guns running subsonic ammo since they tend to cycle very softly. A good option for any AR that cycles too softly to use a heavier buffer or a hydraulic buffer. The recommended combination for .300 BLK with subsonics is to use this buffer with the Sprinco Yellow Reduced Power buffer spring.
