From reviews, and me looking at their guns and all, it looks to me as if they might be okay, but they are for sure more of a begginer brand. Any begginer willing to pay a little more can get a good starter gun that works fine.
its a name brand which = good
Yes, they are the airsoft division of HK, a weapons manufacturing company.
Kwa is a good top quality brand. Most of their guns are in the $200 to about $380 range.
Echo1 is a very world renowned airsoft company and is very esteemed. They manufacture some of the nicest airsoft guns in the world.
Springs in airsoft are never "modded" they are upgraded. An overall good brand for springs is guarder. Their springs usually run from $15 to $35 dollars. Madbull makes decent AEG springs for the money if you sniper takes an AEG spring (like the A&K SVD).
Yes, it is AEG proline which means it is a fully automatic electronic competition level airsoft.

G&G is a very reliable and good airsoft gun brand. In my opinion i think the G&G raider m4 series is good for anyone beginning airsoft or just wants more firepower.

G&P tends to simply re-brand A&K merchandise. the two are more or less the exact same (like Echo 1 and JG)

The best airsoft MP7 is the WELL brand MP7.
