I am very pleased with my barrel. I have a spyder compact 2000 with most everything upgraded, in fact the barrel was the last thing I replaced and the difference was night and day. Much less noise than stock, and superb shot gruopings.
I was worried when my fav. paint PMI, seemed to small for the barrel. But distance, accuracy, and trajectory were top notch.
Weaknesses:
Its not cheap by any means, It so shiney Im afriad to get it dirty and baby it a lttle too much.
Conclusion:
Awsome looks, Spyder owners drool and ask questions. It might cost a little much, but looks so cool it gives me pride and confidence.
