Sitti and Boomstick (can't compare with a kit though)
System X NME LE
Pure Energy 68/3000
Empire Reloader B
Great kit for both front and back players
Stock NME barrel is the same as .691 in kit. Just different colors...
I recently purchased 4 kits to sell to my fellow NME and other cocker threaded shooters. I decided to take one out to the field and test it out. I found that the 14" tip, after adjusting velocity, gave me that extra "umph" to get my shot across the field. I was throwing ropes w/ Xball bronze, not busting a ball, and hitting my target with ease. I found that the stock barrel of the NME is identical to the .691 tip of the kit. One advantage is that 14" tip. The stock tip is only 12". Only problem with my review is that I did not try any other bore sized paintballs. I have a newfound love for Xball and I find that this barrel kit with the longer barrel throws accruate ropes.
If you would like that extra length and accruate shot across the field, I would def recommend this barrel kit.
The recommended price is $130 but you can get them for around $90+shipping and I have them for $85 shipped :)
