More air efficient
no orings (compared to the efficient 05 ego bolt)
Nothing as of yet.
I put this bad boy into my etek, shooting with stock settings, and compared to the stock bolt i saw a velocity increase of 27 fps...With stock i was shooting 293 +- 6 and with hs shooting 320 +-3. The bolt has less kick due to the fact its both smaller and lighter than the stock, and lowers the noise of the marker its self. With no orings the bolt never has to be lubed, and preforms very well. It is a good solid upgrade.
Very very pleased with it, works as it is said to, no problems yet...
The front of the bolt looks like only the bottom half is open to allow airflow but teh real purpose is to give the ball a slight backspin which is supposed to improve trajectory.......similar concept to a Tippmann Flatline barrel but with not as much distance and backspin
The shots look like it's floating similar to the Flatline.
