Alright, so I get my new Ion from UFD 3 days ago. Man was I hyped. I installed all the accesories that are listed in my setup that are made by UFD, and they seem/work like any other high end marker accesorry. Except for this bolt. This thing seemed like it would be amazing, too. Light, nice annodizing, dual tail O-rings. Do not be fooled. After I installed, lubed, and adjusted my input pressure/dwell to the bolt, I went to sleep for the night. Next day, I dry fire it about 9 times, I see the front of the bolt fly right out of the breech. That's right, the thing is so poorly designed that it snapped RIGHT in half. After I removed it from the breech, I noticed that the tail O-rings were completely torn up. Yet another design flaw. Man, they really f***ed up on this one.I used this bolt for a total of about 10 minutes, maybe fired the gun 20 times with it. And now I'm calling the people I bought it from (Ultimate Paintball) and getting my money back. Supposedly there's a one year warrenty on this thing, and man, thats a good thing. I would honestly never even consider this buying this bolt. Other UFD accesories (Body, Trigger, Feedneck, On/off) are awesome, this thing is just crap, simply put.
Don't waste your time with this product, it is simply poorly designed.
