I've heard that this barrel isn't actually all that bad. The machining is really nice, and even though it's not as tight as you might like, you get good accuracy at range. I've heard of people using the stock TM VSR barrel, which I believe is 6.08, and having very good results. I would recommend buying this set up, and upgrading the barrel later, if you are strapped for cash.

Yeah, very well put. Basically sums up the different types of barrel materials. +1 (Nice poem in your sig, too!)

The Precision unit is very good in that it's cheap, and comes with a nice "starter" barrel, that gives you some time to get some cash for a nicer barrel. I would recommend it over the PDI. However, the PDI is nice in that the buckings cost $10, as opposed to $20 (Firefly or Nineball).

I *think* the PDI chamber takes, exclusively, the W-hold bucking by PDI. No experience with it, but I'm pretty sure it only works with this bucking, made by PDI. However, this hop assembly does take AEG barrels.

Both very similar. PDI is a little more adjustable, because it has two arms, but they're both good. I'd say VSR hop because of the cheaper price.
