[Superman]

I purchased this product when my original plastic power tube cracked (my fault not Tippmanns).

It is a great product. It is super durable and the bolt has a teflon ring that really slicks up the action and makes it move FAST. I actually had to cut down the stock spring to get it to shoot under 300 fps after I installed it. I noticed a slight increase in my shots per tank too.

I probably would not have bought it if my power tube didn't break, but I'm glad I did.
