ACP Top Cocking Spyder New Xtra Low Blow Delrin Bolt

Newer style top cocking bolt pin goes through bolt into striker.

The bolt is constructed entirely of delrin so it is extremely light-weight. The new design of the "Low Blow" bolt requires o-rings for best performance. The o-rings must be lubricated with a light film of oil or grease. This bolt helps to impart a slight back-spin on the ball which will improve accuracy, flatten trajectory, and improve range.


- Imparts a slight back-spin on ball
- Improves accuracy/flattens trajectory
- Dual O-rings reduce blow-back/ball hop
- Increases maximum achievable rate of fire
- Reduces weight/softens recoil
