Can be a little tough to cock, but who cares...
I received the bolt through the mail in a padded brown envelope...the first thing I did was tear it open and dig out my gun. Let me tell you, there is some real meaning to "tigershark bolt." This thing looks awesome...and it fits the gun like a glove.
I didn't get the chance to field test it for a few days, but it was definitely worth the wait. This bolt not only reduced the weight of my gun, but it cut down on blowback and sound. With the stock bolt, my Spyder Xtra was extremely loud with a sort of "pinging" sound accompanying every shot. Not true with this bolt - it is a perfect fit for the gun.
On top of all that, this bolt has better airflow than the stock bolt since it lacks a venturi, and it DOESN'T chop balls. I shot approx. 1000 balls and didn't chop a single ball.
APM Products was extremely easy to deal with. I ordered through their website and received prompt email receipts and the product shipped the next day. It took a couple extra days to receive but that's because they are located in Canada. Great company.
I haven't tried any other aftermarket bolts, but I see no reason to after getting this one. This bolt only costs $15 plus $3 shipping and it works perfectly...if you're looking for an inexpensive but highly effective upgrade get this bolt.
