20 oz PMI CO2 Tank
Doesn't swell like Delrin
Cocking rod seems flimsy
I didn't notice much difference in the noise
This is a very nice aftermarket bolt, and I'm glad I got it for my Rodeo. I had to turn down the velocity of the stock setting because the bolt sends all the air directly to the ball. With lesser quality "house paint" it blows em to bits in the barrel. Once I corrected the velocity it shoots like a dream. I bought this on ebay for $20 plus shipping and it did take awhile. It's worth it if you don't need it right away. They say they are working on it though. The light weight of the bolt and the direct airflow is more efficient in gas consumption to so you'll get more shots per tank. All in all it's a very nice bolt. Good job Spudnuk'l...
Get it if you are think about upgrading your bolt. It's better than those other Delrin bolts because they will swell if you get paint on them. The you'll have an 80 dollar piece of junk. At the price you pay for Spudnuk'l bolts, you can't go wrong with this one. Get it! Gets a 9 only for the cocking rod but you can buy one that's threaded to take a cocker rod.
