TDS MP5-
 

Anyone know how well TDS makes their guns and what they can compare to?
I may buy an MP5 made by TDS for a good price, but I need an idea on the quality and efficiency of the gun, and the upgrade potiential...

TSD makes (or rebrands) anything from cheap clearsoft shit to full metal guns, I believe. So it's really a wide area of quality.

The advice, like anything else; never buy crap.
How can you know what is good? Go see what folks use at games. Crap guns dont tend to even show up at games for a lot of good reasons.
