I just recently purchased a 2.0 and saw that ANS gear has Stinger Bolt - Modded w/spring, Fully Adjustable Bolt Guide, Low Pressure Firing Can on sale. Is there any noticeable difference in these compared to the 2.0 core?

keep the internals stock.. the only thing I liked from NDZ was their trigger. Beats the critical trigger because it still uses the stock adjustment screws and has the same trigger pull feel as stock

I purchased a bolt from Chris at Pootypaintball.com. I did notice a difference on air efficiency and consistency on my 2.0. Unfortunately, without a reg pressure tester, I can't say exactly how much from stock. He does have test videos on his website though.
