The new upgrade bolt from TechT will help make your TM-7 or TM-15 more air efficient, achieve higher rates of fire and reduce the amount of Kick. TechT achieves these aspects by simply reducing the weight of the bolt and changing the material to Delrin. The stock bolt weighs about 16.5grams while TechT's bolt weighs about 6.5grams, this is more then half of the original weight! With the reduce in weight, there is less mass moving which in turn reduces the amount of recoil, less air and being extremely light weight will help increase the amount of speed the bolt can cycle. By reducing the weight of the bolt, TechT has made a great upgrade for your BT TM markers when you need a higher rate of fire, less recoil and more shots per tank.
- Weighs less then half of the original bolt at 6.5grams
- Delrin material used on the bolt which is a self lubricating material that will last longer
